BASIC MAIN VALVE

Most CLA-VAL valves consist of a main valve and pilot control system. The basic main valve is called a Hytrol Valve.

When no pressure is in the valve, the spring and the weight of the diaphragm assembly hold the valve closed.

With the cover chamber vented to atmosphere, the valve will open from line pressure under the disc.

If inlet pressure is connected into the cover chamber, the valve closes tightly. In this example, the 400 pound difference is the force which pushes the disc against the seat and causes the valve to seal drip-tight.

NON-MODULATING CONTROLS

A simple control which either opens the valve wide or closes it tightly is a three-way valve. The type of operation this control gives is called “non-modulating” because the valve cannot pause in a partially open position.

To open...

Control is turned to exhaust cover chamber pressure.

Ordinary three-way valves usually are not satisfactory because they require so much force to operate. An easy-turning control which can be operated in a variety of ways is usually used. Several examples of controls and their operation are shown at right.

With a solenoid

Once the control is turned to either position, operating fluid flow into or out of the cover chamber until the valve is open or closed. For example...

To close...

Control is turned to apply pressure to cover chamber.

Page 8

MODULATING CONTROLS

The Cla-Val Automatic Control Valve modulates if the cover pressure is held between the inlet and outlet pressure. To achieve modulating operation, a slightly different type of control system is utilized.

Valve Open

When the throttling control opens to a point where more pressure is relieved from the cover chamber than the restriction can supply, cover pressure is reduced and the valve opens.

Valve Throttling

The main valve modulates to any degree of opening in response to changes in the throttling control. At an equilibrium point, the main valve opening and closing forces hold the valve in balance. This balance holds the valve partially open, but immediately responds and readjusts its position to compensate for any change in the controlled condition.

Valve Closed

When the modulating control closes sufficiently to direct a great enough pressure into the cover chamber to overcome opening forces of line pressure, the main valve closes.

AUTOMATIC CONTROLS

The following examples illustrate several different types of operation utilizing automatic controls.

Pressure Reduction

Outlet pressure on control diaphragm causes the main valve to hold a steady outlet pressure.

Pressure Relief

Inlet pressure on control diaphragm causes the main valve to hold a steady inlet pressure.

Liquid Level Controller

Slight changes in flow through the float control causes main valve to counteract changes in reservoir level so liquid level is held constant.

Rate of Flow Controller

Limits the maximum flow rate by changes to the main valve counteract any slight changes in differential pressure across an orifice plate located in the main line.

pressure reduction

• Diagonal disc guide slots direct flow away from surfaces.

Which way should fluid flow through a CLA-VAL Valve?

Just as with any globe valve, the usual way is “under–the–disc” as shown.

The main exception to the “under-the-disc” rule of thumb is the check valve.

“Under-the-Disc”

What purpose does the

internal spring in the Hytrol valve serve?

To provide enough force to close the valve when

no difference exists between inlet, cover and outlet pressures. When the inlet pressure is greater than outlet pressure (even by a small amount) the hydraulic forces, -- NOT THE SPRING hold the valve tightly closed.

Can the opening and closing speed of a CLA-VAL Valve be controlled?

Yes. It is a matter of controlling the rate at which operating fluid flows into or out of the cover chamber.

Here is a typical valve equipped with both opening and closing speed controls. A simple needle valve can be used for these controls.

Normal so valve closes against the pressure

Can pressure other than line pressure be used to operate CLA-VAL Valves?

Yes. Frequently, when line fluid is too dirty or otherwise unsuitable, a separate source of pressure is desired. Clean water, air (with some limitations), or oil

are suitable. The important point is to make sure the operating pressure is equal or greater than inlet pressure AT ALL TIMES.

What should be done if line pressure is very low? (Below 10 psi)

Usually a separate source of operating pressure is required. A spring to open

the valve may be necessary. Consult the factory for recommendations.

(Sizes 3/8"-36")

Hytrol Valve

• Drip-Tight, Positive Seating

• Service Without Removal From Line

• Threaded, Flanged or Grooved Ends

• Globe or Angle Pattern

• 100% Factory Tested

The Cla-Val Model 100-01 Hytrol Valve is a hydraulically operated, diaphragm actuated, globe or angle pattern valve. It consists of three major components: body, diaphragm assembly, and cover. The diaphragm assembly is the only moving part.

The diaphragm assembly is guided top and bottom by a precision machined stem. It utilizes a non-wicking diaphragm of nylon fabric bonded with synthetic rubber. A resilient synthetic rubber disc retained on three and one half sides by a disc retainer forms a drip-tight seal with the renewable seat when pressure is applied above the diaphragm.

The Model 100-01 is the basic valve used in nearly all Cla-Val Automatic Control Valves. It is the valve of choice for system applications requiring remote control, pressure regulation, solenoid operation, rate of flow control, liquid level control or check valve operation. The rugged simplicity of design and packless construction assure a long life of dependable, trouble-free operation. It is available in various materials and in a full range of sizes, with either threaded, flanged or grooved ends. Its applications are unlimited.

Principle of Operation

On-Off Control

Full Open Operation

When pressure in the is relieved to a zone of lower pressure, the line pressure at the valve inlet opens the valve, allowing full flow.

cover chamber

On-Off Control

Tight Closing Operation

When pressure from the valve inlet is applied to the cover chamber, the valve closes drip-tight.

Modulating

Control

Modulating Action

The valve holds any intermediate position when operating pressures are equal above and below the diaphragm. A Cla-Val “Modulating” Pilot Control will allow the valve to automatically compensate for line pressure changes.

Cla-Val Control Valves operate with maximum efficiency when mounted in horizontal piping with the main valve cover UP, however, other positions are acceptable. Due to component size and weight of 8 inch and larger valves, installation with cover UP is advisable. We recommend isolation valves be installed on inlet and outlet for maintenance. Adequate space above and around the valve for service personnel should be considered essential. A regular maintenance program should be established based on the specific application data. However, we recommend a thorough inspection be done at least once a year. Consult factory for specific recommendations.

MODEL

(Full Internal Port)

Powertrol Valve

• Drip-Tight, Positive Seating

• Service Without Removal From Line

• Threaded or Flanged Ends

• Globe or Angle Pattern

• Every Valve Factory Tested

The Cla-Val Model 100-02 is a hydraulically operated, diaphragm actuated, globe, or angle pattern valve. It consists of four major components: body, intermediate chamber, diaphragm assembly, and cover. The diaphragm assembly is the only moving part.

The diaphragm assembly which is guided top and center by a precision machined stem, utilizes a non-wicking diaphragm of nylon fabric bonded with synthetic rubber. The diaphragm forms a seal between the cover chamber and intermediate chamber. A synthetic rubber disc retained on three and one half sides forms a drip-tight seal with the renewable seat when pressure is applied above the diaphragm. As pressure above the diaphragm is relieved and pressure is applied below the diaphragm, the valve opens wide for full flow. The rate of closing or opening can be controlled by modulating flow into or out of the diaphragm chambers.

The Model 100-02 is recommended where independent operating pressure is desired. Available in various materials and in a full range of sizes, with either threaded or flanged ends, its applications are many and varied.

Principle of Operation

Four-Way Control

Full Open Operation

When operating pressure below the diaphragm is applied and operating, pressure is relieved from the cover chamber and, the valve is held open, allowing full flow.

Four-Way Control

Tight Closing Operation

When pressure below the diaphragm is relieved and operating pressure is applied to the cover chamber, the valve closes drip-tight.

Four-Way Control with Lock

Modulating Action

The valve holds any intermediate position when operating pressure is equal above and below the diaphragm. A Cla-Val four-way pilot control with "lock" position can maintain this balance by stopping flow in the pilot control system.

MODEL

Powercheck Valve

• Built-in Automatic Check Valve

• Globe or Angle Pattern

• Drip-Tight, Positive Seating

• Threaded or Flanged Ends

• Packless Construction

The Cla-Val Model 100-03 Powercheck Valve is a hydraulically operated diaphragm valve with a built-in check feature to prevent return flow. Available in globe or angle pattern, it consists of four major components: body, intermediate chamber, diaphragm assembly, and cover. The diaphragm assembly is the only moving part.

The diaphragm assembly is guided top and center by a precision machined stem and utilizes a non-wicking diaphragm of nylon fabric bonded with synthetic rubber. A synthetic rubber disc retained on three and one half sides forms a driptight seal with the renewable seat when pressure is applied above the diaphragm. When pressure above the diaphragm is relieved, the valve opens wide. The rate of closing or opening can be controlled by modulating flow into or out of the diaphragm chambers.

When a pressure reversal occurs, the valve will immediately close, preventing reverse flow thru the valve. The split stem will allow the disc retainer assembly to check closed regardless of the position of the diaphragm.

Principle of Operation

Four-Way Control

Full Open Operation

When operating pressure below the diaphragm is applied and pressure is relieved from the cover chamber, the valve is held open allowing full flow.

Note: For optimum operation of built-in check feature, installation with stem vertically up is recommended.

Tight Closing Operation

When pressure below the diaphragm is relieved and operating pressure is applied to the cover chamber, the valve closes drip-tight.

Four-Way Control

When a static condition or pressure reversal occurs, the split stem

design allows the valve to instantly check closed. Return flow is prevented regardless of the diaphragm's position.

MODEL

600 Series

Hytrol Valve

• Reduced Cavitation Design

• Drip-Tight, Positive Seating Action

• Service Without Removal From Line

• Globe or Angle Pattern

• Every Valve Factory Tested

The Cla-Val Model 100-20 Hytrol Valve is a hydraulically operated, diaphragm actuated, globe or angle pattern valve. It consists of three major components: body, diaphragm assembly and cover. The diaphragm assembly is the only moving part.

The diaphragm assembly is guided top and bottom by a precision machined stem which utilizes a non-wicking diaphragm of nylon fabric bonded with synthetic rubber. A resilient synthetic rubber disc, retained on three and one-half sides by a disc retainer, forms a drip-tight seal with the renewable seat when pressure is applied above the diaphragm.

The reduced cavitation characteristics of the 100-20 Hytrol Valve is the basis for the Cla-Val 600 Series. The rugged simplicity of design and packless construction assure a long life of dependable, trouble-free operation. It's smooth flow passages and fully guided disc and diaphragm assembly assure optimum control when used in piping systems requiring remote control, pressure regulation, solenoid operation, rate of flow control or check valve operation.

Available in various materials and in a wide range of sizes. It's applications are unlimited.

Principle of Operation

On-Off Control

Full Open Operation

When pressure in the is relieved to a zone of lower pressure, the line pressure at the valve inlet opens the valve, allowing full flow.

cover chamber

On-Off Control

Tight Closing Operation

When pressure from the valve inlet is applied to the cover chamber, the valve closes drip-tight.

Modulating

Control

Modulating Action

The valve holds any intermediate position when operating pressure is equal above and below the diaphragm. Using a Cla-Val “Modulating” Control will allow the valve to automatically compensate for line pressure changes.

Service and Installation

Cla-Val Control Valves operate with maximum efficiency when mounted in horizontal piping with the main valve cover UP, however, other positions are acceptable. Due to component size and weight of 10 inch and larger valves, installation with cover UP is advisable. We recommend isolation valves be installed on inlet and outlet for maintenance. Adequate space above and around the valve for service personnel should be considered essential. A regular maintenance program should be established based on the specific application data. However, we recommend a thorough inspection be done at least once a year. Consult factory for specific recommendations.

MODEL

• Compact Design, Proven Reliable

• High Pressure Rating Availability

• Easy Installation and Maintenance

The Cla-Val Model 100-42 Roll Seal valve is a hydraulically operated valve used to control liquid flow by means of a flexible control element: the liner. The basic valve consists of only two parts: a one piece, investment cast body and an elastomeric liner. The valve body is constructed with internal ribs and slots forming a grillwork which surrounds the liner to provide support. A normally closed type valve is formed by the installed liner which covers the grillwork and seats against the raised seating surface in the valve body. Upstream pressure actuates the valve to produce valve opening by rolling the liner off the seating surface and the slotted grillwork. The valve is actuated by upstream pressure as the loading pressure (pressure supplied to the control chamber) is varied by an external pilot control system. A typical pilot control system used to operate the Model 100-42 valve consists of a restriction and a suitable pilot connected to the valve.

Principle of Operation

Model 100-42 Valve

in Closed Position

Upstream pressure is introduced to the control chamber (the chamber formed behind the liner) of the Cla-Val Model 100-42 Roll Seal valve through the control piping and restrictor. When the pilot is closed, full inlet pressure is supplied to the control chamber, thus balancing the force developed by inlet pressure acting on the upstream face on the liner. Under these conditions, the liner remains in the fully closed position. Since the operating pressure in the control chamber is greater than the outlet pressure, an additional closing force is developed across the liner, pressing the liner against the surrounding slotted grillwork area and seating surface.

PILOT CONTROL VALVE

RESTRICTOR

SEATING AREA

INLET

CONTROL CHAMBER

Model 100-42 Valve

in Partially Open Position

As loading pressure is lowered slightly below inlet pressure, the central portion of the liner is forced to invert and come to rest against the tip of the control chamber cavity. Reducing the loading pressure further (but still higher than outlet pressure) causes the liner to drape over the cone shaped portion of the control chamber cavity. This action causes the outer section of the liner to roll off the seating surface and a portion of the grillwork to partially open the valve.

Model 100-42 Valve

in Fully Open Position

The valve is fully opened when loading pressure is sufficiently reduced to allow the liner to roll back completely and expose the full slot area. Restoring loading pressure reverses the liner rolling action to return the liner to the fully closed position.

316SS Hytrol Valve

• All 316 Stainless Steel

• Reduced Cavitation Design

• Drip-Tight, Positive Sealing Action

• Service Without Removal From Line

• Every Valve Factory Tested

• Three-Year Warranty

The Cla-Val Model 100-44 Hytrol 316SS Valve is a hydraulically operated, diaphragm actuated, globe pattern valve with all 316 Stainless Steel metal parts. Specially designed 316 Stainless Steel removable slip-on flanges provide 150 or 300 ANSI class flange connections that meet ANSI and ISO standards. This valve is ideal for control valve applications where fluid compatibility is often a problem. The standard Electropolish finish on the 316 Stainless Steel parts offers extreme corrosion resistance to many industrial fluids such as seawater, high alkyl or high acid concentrations or other aggressive or corrosive fluids.

The Model 100-44 Hytrol consists of these major components: body, flanges, diaphragm assembly and cover. The diaphragm assembly is the only moving part and is guided top and bottom by a precision-machined stem. A non-wicking diaphragm of nylon fabric reinforced, synthetic rubber creates the control chamber for the valve. A resilient, synthetic rubber disc forms a drip-tight seal, with the renewable seat, when pressure is applied to the control chamber. The rugged simplicity of design and packless construction assures a long life of dependable, trouble-free operation. Smooth flow passages and fully guided diaphragm assembly assure optimum control, when used in piping systems requiring remote control, pressure regulation, solenoid operation, rate of flow control or check valve operation.

Principle of Operation

On-Off Control

Full Open Operation

When pressure in the ber is relieved to a zone of lower pressure, the line pressure at the valve inlet opens the valve, allowing full flow.

Anti-Cavitation Main Valve

KO Anti-Cavitation Trim

Cla-Val’s KO anti-cavitation trim represents a dramatic departure from the standard approaches usually employed to fight cavitation in valves that are required to undergo extreme pressure differentials and high velocity flow conditions.

Constructed of 316 Stainless Steel, the seat and disc guide feature dual interlocked sleeves containing cast radial slots that deflect internal flow to impinge upon itself, harmlessly dissipating potential noise and cavitation damage. The cast radial slots create a larger flow path than is possible with the standard drilled holes typically employed by other anticavitation valves currently available in the market place. The uniquely designed radial slots in the seat and disc guides also lessen the possibility of fouling if small particles are present in the water.

Cla-Val KO Anti-Cavitation Valve Principals of Operation

First Stage Pressure Reduction

• Flow enters through seat slots and reduces pressure

Second Stage Pressure Reduction

• Flow impinges upon itself within the seat and disc guide assembly to dissipate cavitation and further reduce pressure

Third Stage Pressure Reduction

• Flow exits through disc guide for final pressure reduction

• Diagonal disc guide slots direct flow away from surfaces

The dark shaded portion of the chart illustrates the region where cavitation damage may occur. The lighter shaded portion is where significant cavitation noise and vibration may occur. Operating conditions inside the dark shaded area is permissible for infrequent periods of short duration. The guide is for modulating service valves. For on/off valves, consult factory.

The chart is based on cavitation index (sigma) values as defined by Utah State University Water Research Laboratory.

The dark shaded portion is below of 0.5 and the lighter shaded area is below of 0.8. The chart is to be used for typical valve operating conditions below 40% open at standard water temperature and elevation below 1000 feet.

More accurate cavitation conditions are determined from the Cla-CAV analysis program including static and dynamic inlet and outlet pressures, flow range, elevation, water temperature, and service conditions. If operation is inside the shaded areas, the Cla-CAV analysis can be used to determine whether added backpressure from an orifice plate, a second valve in series, or adding KO Anti-Cavitation trim (see 100-01KO data sheet). is necessary.

CAVITATION GUIDE

CLA-CAV DETAILED ANALYSIS CHART

For a more detailed cavitation analysis or if operation will be outside of the above chart, request a Cla-CAV computer analysis. Cla-CAV can evaluate what options best solve any potential cavitation problem. In the example shown, a 6 inch 100-01 modulating service valve requires an orifice plate downstream to prevent damaging cavitation. For wider flow range service, either an extra valve in series or the addition of KO Anti-Cavitation trim to the valve may be necessary (see 100-01KO data sheet). Consult factory for a free analysis for wide open or modulating service valves.

Pressure Relief & Pressure Sustaining Valve

• Accurate Pressure Control

• Optional Check Feature

• Fast Opening to Maintain Line Pressure

• Slow Closing to Prevents Surges

• Completely Automatic Operation

The Cla-Val Model 50-01/650-01 Pressure Relief Valve is a hydraulically operated, pilot-controlled, modulating valve designed to maintain constant upstream pressure within close limits. This valve can be used for pressure relief, pressure sustaining, back pressure, or unloading functions in a by-pass system.

In operation, the valve is actuated by line pressure through a pilot control system, opening fast to maintain steady line pressure but closing gradually to prevent surges. Operation is completely automatic and pressure settings may be easily changed.

If a check feature is added, and a pressure reversal occurs, the downstream pressure is admitted into the main valve cover chamber, closing the valve to prevent return flow.

This fast opening, slow closing relief valve provides system protection against high pressure surges on pump start up and pump shut down by dissipating the excess pressure to a safe location.

Pressure Sustaining Service

When installed in a line between an upper zone and a lower area of heavy demand, the valve acts to maintain desired upstream pressure to prevent "robbing" of the upper zone. Water in excess of pressure setting is allowed to flow to an area of heavy demand, control is smooth, and pressure regulation is positive.

The Cla-Val Model 52-03/652-03 Surge Anticipator Valve is indispensable for protecting pumps, pumping equipment and all applicable pipelines from dangerous pressure surges caused by rapid changes of flow velocity within a pipeline.

When pumping systems are started and stopped gradually, harmful surges do not occur. Should a power failure take place, however the abrupt stopping of the pump can cause dangerous surges in the system which could result in severe equipment damage.

Power failure to a pump will usually result in a down surge in pressure, followed by an up surge in pressure. The surge control valve opens on the initial low pressure wave, diverting the returning high pressure wave from

The Cla-Val Model 58-01/658-01 valve performs two separate functions. It maintains a constant back pressure by discharging excess pressure downstream and when the solenoid is activated the valve closes drip-tight.

In operation, the valve is actuated by hydraulic line pressure through the pilot control system. When inlet pressure is greater than the control setting, the valve opens. When inlet pressure is equal to the control setting, the pilot modulates the valve, maintaining the preselected back pressure. When inlet pressure is less than the control setting, the pilot system closes the valve drip tight. Changing the pressure setting simply involves turning an adjusting screw on the pilot control.

The solenoid control is available in energize to open or de-energize to open models.

Pressure Relief, Sustaining & Back Pressure Valve

Description

The Cla-Val Model 750-01 is a hydraulically operated pilot actuated automatic control valve for pressure sustaining, relief and/or back pressure service. The main valve consists of only two parts, a stainless steel body and an elastomeric liner or control element.

The main valve will open when inlet pressure begins to exceed a preset pressure and will allow enough flow to maintain that inlet pressure. In pressure sustaining service, Model 750-01 will conserve pressure in an upper system during periods of high demand in a system below. In pressure relief service, the Model 750-01 will modulate to exhaust line pressure to keep it below a set point maximum. On a pump bypass system, the valve will allow flow back to the pump suction when pump discharge pressure exceeds the set point.

Cla-Val Model 750-01 will control from no flow to full open flow without any chattering or slamming under low flow conditions. For this reason, on by-pass, relief, and pressure sustaining service, there is never a

The Cla-Val Model 250-01/605-01 Differential Pressure Relief Valve is a hydraulically operated, pilot-controlled, modulating valve. It is designed to maintain a constant pressure differential between any two pressure points in a system where the closing of the valve directly causes the differential pressure to increase. The valve tends to open on an increase in differential pressure and close on a decrease in differential pressure.

In operation, the valve is actuated by line pressure through a pilot control system sensing from two points across which a differential is to be maintained. Operation is completely automatic and pressure settings may be easily changed.

Pressure Reducing Valve with

Low Flow By-Pass

• Modulating Control

• Maintains Constant Outlet Pressure Over a

Wide Range of Flows

• Durable Construction

• Convenient and Space Saving

The Cla-Val Model 90-48/690-48 Pressure Reducing Valve with Low Flow By-Pass automatically reduces a higher inlet pressure to a steady lower downstream pressure, regardless of changing flow rate. The low flow by-pass capability is achieved by using the ClaVal Model CRD-40 Direct Acting Pressure Reducing Valve as an integral part of the main valve. By doing this, space is saved and installation and maintenance become much easier.

The pressure reducing valve is hydraulically operated and controlled by a Cla-Val CRD pilot control, which senses pressure at the main valve outlet. An increase in outlet pressure forces the CRD pilot control to close and a decrease in outlet pressure opens the control. This causes the main valve cover pressure to vary, modulating the main valve, thereby, maintaining constant outlet pressure.

*The optional closing speed control on this valve should

Typical Applications

This valve has the flexibility to be installed in a distribution system where the demand varies over a wide range. This frequently occurs in industrial, residential, educational, high-rise buildings and other applications. Another important feature of the valve is its space efficient configuration, allowing easy installation and maintenance.

The Model CRD-40 low flow pressure reducing by-pass is preset to a higher pressure than the CRD pilot control. The CRD-40 responds to pressure changes at the main valve outlet. When the CRD closes, the Model CRD-40 remains open, allowing low flow to by-pass the main valve. The CRD-40 closes when the flow decreases and the downstream pressure reaches its set-point .

The Cla-Val Model 90-48/690-48 is not a substitute for a low flow bypass valve in all cases. This valve is commonly used in building where 1-15 gpm low flows are common in off peak usage. The bypass on this valve is limited to the body tapping size on the main valve.

The Cla-Val Model 92-01/692-01 Combination Pressure Reducing and Pressure Sustaining Valve automatically performs two independent functions. It maintains a constant downstream pressure, regardless of fluctuating demand and sustains the upstream pressure to a pre-determined minimum.

The pressure reducing control responds to slight variations in downstream pressure and immediately repositions the main valve to maintain the desired downstream pressure. The pressure sustaining control is normally held open by the upstream pressure, but modulates should the pressure drop to the control set point. This, in turn, modulates the main valve to sustain the desired upstream pressure.

Typical Application

Should the downstream pressure suddenly increase above the setting of the pressure reducing control due to on-off operation of two or more downstream systems, the Surge Control tracks rapidly enough to prevent high pressure surges from entering any of the downstream systems, when any one of the downstream systems is rapidly closed off. The typical combination pressure reducing and surge control valve station uses Model 94-01BY/694-01BY to control surges in downstream piping as remote control valves change from one downstream zone to another. Surge Control is set approximately 10 psi above Pressure Reducing Control to prevent high pressure surge entering other downstream zones.

The Cla-Val Model 990 Pressure Reducing Valve automatically reduces a higher inlet pressure to a steady lower downstream pressure with our unique balanced design. This valve is an accurate regulator capable of holding downstream pressure to a predetermined amount, regardless of upstream pressure fluctuations.

Periodic maintenance consist of regular cleaning of internal strainer that is accessed by removing bottom plug. There are no user serviceable components.

Typical Applications

High rise buildings use 990 Pressure Reducing Valves

in various water systems (potable water, boiler feed air conditioning, etc.) to control pressure fluctuations between floors.

Industrial plants use 990 Pressure Reducing Valves between a high pressure supply system and equipment requiring lower pressure. Typically 990 Pressure Reducing Valves are used at supply connections for water heaters, boiler feed water or other process water systems.

Municipal water systems use 990 Pressure Reducing Valves at service connections in a high pressure distribution zone.

Depending on flow requirements, 990's may be installed in parallel. One 990 provides desired outlet pressure while the second 990 handles low flow conditions. If necessary, additional 990s can be added for more flow capacity. The 990 is also ideal for a low flow bypass around a larger Cla-Val 90 Series Pressure Reducing Valve.

Pressure Reducing Valve

Description

The Cla-Val Model 790-01 is a hydraulically operated, pilot actuated automatic control valve for pressure reducing service. The main valve consists of only two parts: a stainless steel body, and an elastomeric liner or control element.

Pressure reducing valves are used to lower pipeline pressure to a predetermined set point. Cla-Val Model 790-01 automatically controls downstream pressure, from no flow to full open flow, without regard to changes in inlet pressure. Outlet pressure control is smooth and precise since the friction and hysteresis of the valve and pilot is negligible.

Because the valve will not chatter or slam under low flow conditions, it is not necessary to parallel Cla-Val Model 790-01 with a second smaller size control valve to obtain accurate pressure control at low flow rates. In any size, Cla-Val Model 790-01 will control pressure right down to shutoff.

The Cla-Val Model 98-06/698-06 Pressure Management Control Valve is a pressure reducing valve that allows for two downstream set points. A high pressure set point is selected for high flow demand and a low pressure set point is selected for low flow demand. This dual set point arrangement allows for reduction in water loss by not over pressurizing the system during times of low demand, while providing adequate pressure during high or fire demand. The design is 100% hydraulic and in addition to the dual pressure set points the transition point at which the pressure changes based on the flow is adjustable as well. The patent pending design of the valve allows for smooth transition from one

Pressure Reducing Valve with Two Stage - Solenoid Selected Pressure

• Two Adjustable Setpoints

• Sensitive and Accurate Pressure Control

• Ideal For Use with SCADA System

• Low Power Required

• Low Maintenance Cost

The Cla-Val Model 90-11 Two-Stage Pressure Reducing Control valve allows selection between two different pressure-reducing set points. It has one pilot set at a higher pressure setting; a second pilot set at a lower pressure setting and a solenoid control to select the active pilot control for the main valve. The valve smoothly changes setpoint and will control pressure regardless of inlet pressure fluctuations or downstream demand changes. Set point switching is achieved by energizing the solenoid control for the desired time that the low pressure is needed. The two set points are easily changed in the field.

This valve is suitable for many pressure control applications where downstream conditions change sufficiently to require a lowered pressure during part of the time. A variety of electronic controls can be use with the 90-11 ranging from a simple battery powered timer to extensive SCADA systems. In leakage abatement applications, the 90-11 offers simplified two-pressure control of a distribution zone. For times of high demand, the higher pressure control is used and for times of low demand, the lower pressure control is selected.

The Cla-Val Model 124-01/624-01 Float Valve is a non-modulating valve that accurately controls the liquid level in tanks. This valve is designed to open fully when the liquid level reaches a pre-set low point and close drip-tight when the level reaches a preset high point.

This is a hydraulically operated, diaphragm valve with the pilot control and float mechanism mounted on the cover of the main valve. The float positions the pilot control to close the valve when the float contacts the upper stop. The high and low liquid levels are adjusted by positioning the stop collars on the float rod. The difference between high and low levels can be adjusted to as little as one inch, or to as much as eighteen inches.

Level settings can be as much as eleven and one half feet below the valve. The float mechanism may be located remotely from the main valve. See the technical data sheet on Model CF1-C1 Float Control for additional information.

The Cla-Val Model 129-01/629-01 Float Valve maintains a relatively constant level in storage tanks and reservoirs by admitting flow into the tank in direct proportion to the flow out of the tank. It is a hydraulically operated, pilot controlled, diaphragm valve. The rotary disc type float operated pilot control is installed at the high liquid level in the reservoir and is connected via tubing or pipe to the main valve. As the liquid level changes, the float control proportionally opens or closes the main valve, keeping the liquid level nearly constant. If the check feature option "D" is added and a pressure reversal occurs, the downstream pressure is admitted into the main valve cover chamber and the valve closes to prevent return flow.

The Cla-Val Model 428-01/628-01 Float Valve modulates to maintain a constant liquid level in a storage tank by compensating for variations in supply or demand. It can be installed to control the flow into or out of the tank by either closing on a rising level or opening on a rising level. This valve is a hydraulically operated, pilot controlled diaphragm valve.

The pilot control system consists of an integral variable orifice in the main valve cover and a remotely mounted float control. A slight change in liquid level moves the float control. This action varies the pressure in the valve cover, causing the main valve to seek a new position. The integral variable orifice automatically regulates the flow into the cover chamber until the valve reaches a position that is in direct relation to the position of the float control.

The Cla-Val Model 210-09/610-09 Combination Altitude and Back Pressure Valve controls the high water level in reservoirs without the need for floats or other devices. The valve modulates to maintain upstream pressure within close limits to prevent over drawing system supply while filling reservoir. When the shut-off point of the hydraulic pilot control is reached, the valve closes smoothly without surges. This valve is designed for one-way flow only.

The 210-09/610-09 Valve is hydraulically-operated and pilot-controlled for optimum automatic level and pressure control. The level pilot control operates on a differential in forces between spring load and reservoir head level. When force of spring is overcome by force of reservoir head, the pilot shifts and closes main valve. Desired high water level is set by adjusting spring force. The level pilot control measures the reservoir head through a customer supplied separate sensing line* connected directly to reservoir. The pressure sustaining pilot control senses upstream system pressure and modulates the main valve more open on a rise in pressure to maintain a minimum inlet pressure when filling reservoir.

The valve can also be furnished with auxiliary controls to meet the need for additional functions, such as: rate of flow control, pressure reduction, solenoid override, etc. If the check feature option is added and a pressure reversal occurs, reservoir pressure is admitted into main valve cover chamber and valve closes to prevent return flow.

• Accurate and Repeatable Level Control

• Easy Interface With Remote Control Systems

• Drip Tight Positive Shut Off

• Reliable Hydraulic Operation

• Easily Adjustable Control

The Cla-Val Model 210-17/610-17 Altitude Valve controls the high water level in reservoirs with out the need for floats or other devices. It is a non-throttling valve that remains fully open until the solenoid is activated or the shut-off point of the hydraulic pilot control is reached. The valve closes at high water level and opens for return flow when the pressure at the valve inlet is less than reservoir pressure.

This valve is hydraulically-operated and pilot-controlled. The level pilot control operates on the differential in forces between a spring load and reservoir head level. When force of the spring is overcome by the force of reservoir head, the pilot shifts and closes main valve. Desired high water level is set by adjusting the spring force. The pilot control measures the reservoir head through a customer supplied separate sensing line* connected directly to the reservoir. A three-way solenoid control and a high-capacity three-way pilot control valve provide override shutoff of valve from a remote location, such as a SCADA control system. It is furnished either normally open (de-energize solenoid to open) or normally closed (energize solenoid to open).

The valve can also be furnished with auxiliary controls to meet the need for additional functions, such as: pressure sustaining, rate of flow control, pressure reduction, etc.

Improved Filter Backwashing

Advanced Cla-Val Electronic Backwash Valves with metering capability

All water treatment plant filters must be regularly backwashed to clear away impurities left by raw water and to ensure optimum filtration results. Conventional systems, utilizing a combination of devices, often succumb to the ravages of cavitation caused by high system pressure and pose space challenges because of the long runs of piping required between components to guarantee proper function.

Cla-Val electronic metering valves equipped with KO anti-cavitation trim can handle the pressure and can perform the backwashing function without external metering or control components, greatly reducing space requirements and installation/maintenance costs.

This multi-functional control valve cost effectively meets the following operational requirements:

• Low-rate wash • High-rate wash

• Remote valve closure • Flow metering and totalizing

• Hydraulic pressure override • Can interface with SCADA systems

In addition to being available on new valves, any existing, installed Cla-Val Pressure Reducing Valve can be field retrofitted with the Model 133 electronic control and metering kit to perform backwashing at peak efficiency.

How It Works

The Cla-Val Model 138-01/638-01 Electronic Actuated Positioning Control Valve regulates flow or pressure or other system parameter by changing valve position from full open to shut-off. Exact valve position for large-scale waterworks or industrial applications is achieved with CPC pilot control that consists of electronic actuator and hydraulic pilot sub-assembly. The CPC controls valve position by limiting valve opening using hydraulically-assisted technology. The pilot sub-assembly has two calibrated orifices that are positioned proportional to valve position to vary main valve control chamber operating pressure. The CPC actuator creates slight changes in orifice position and in turn operating pressure hydraulically changes valve position. The pilot sub-assembly requires very little torque and is virtually frictionless for long service life. The actuator features high repeatable-accuracy brush-less motor technology and low energy consumption. Precision, no-contact hall-effect internal position sensor assures accuracy and durability. The CPC has factory pre-configured parameters of full valve stroke, preset rotation speed, and default setting on loss of set point. Actuator parameters can be changed using free downloadable software and special USB cable. Valve fully-closed position is assured by signaling solenoid to lock control pressure in main valve operating chamber when valve is very close to seat (adjustable). Operating on 24 VDC and with customer supplied battery backup, the 138-01/63801 valve can eliminate downtime due to power failures.

The Cla-Val CPC Electronic Actuated Positioning Control regulates flow through Cla-Val Main Valves by changing valve position from full open to shut-off. The CPC consists of electronic actuator and hydraulic pilot sub-assembly. The CPC controls valve position by hydraulically limiting valve opening with hydraulically-assisted pilot modulating main valve. The pilot sub-assembly has two calibrated orifices that are positioned proportional to valve position to vary Cla-Val basic valve control chamber operating pressure. The CPC actuator creates slight changes in orifice position and in turn operating pressure hydraulically changes valve position. The pilot sub-assembly requires very little torque and is virtually frictionless for long service life. The actuator features high repeatable-accuracy brush-less motor technology and low energy consumption. Precision, no-contact hall-effect internal position sensor assures durability. The CPC is factory preconfigured to full stroke, preset rotation speed, and default setting on loss of set point. Actuator parameters can be changed using free downloadable software and special USB cable. Valve fully-closed position is assured by signaling solenoid to lock control pressure in main valve operating chamber when valve is very close to seat (adjustable). Operating on 24 VDC and with customer supplied battery backup, the CPC can eliminate downtime due to power failures.

Typical Applications

Note: When retrofitting an existing valve, high capacity cover bearing must be installed. This requires removing the valve cover. Consult factory for details.

The CPC Electronic Actuated Positioning Control is used with 138 Series Electronic Actuated Control Valves in high rise building chill water circulating system applications. Building SCADA control systems often use multiple circulating system parameters to control valve position for optimizing water circulating system. Also, 138 Series valves are used in large water transmission systems where several system parameters must be controlled by one valve. SCADA system monitors various water distribution system parameters, such as downstream pressure, upstream pressure, tank level, time of day, flow rates in several zones, etc., and then remotely changes 138 Series valve position to meet several system requirements as all parameters continue changing.

Cla-Val 138 Series valves can have optional 133VF Flow Metering System installed for flow rate moni- toring. Consult factory for details.

Installed

• System accurately measures flow rate

• No external meter is required

• For new installations and retrofitting

• Completely self-contained, requiring

12 to 24 VDC power

• Simple integration

The Cla-Val 133VF Flow Metering System is an effective means of obtaining real-time flow data from a Cla-Val control valve regardless of valve function and without an external flow device. Now all Cla-Val control valves in a water distribution system can be economically integrated into SCADA control or pressure and flow management strategies.

The 133VF System is completely self-contained and when factory installed on new Cla-Val automatic control valves or field installed on existing valves, accurately measures flow rate and transmits it as a 4 - 20 mA analog signal. It can be used on virtually all valve sizes from two through twenty-four inch and is typically used at pressure reducing, back pressure, flow limiting, and level control valve stations.

The system features the “heart” of the 133-01 Flow Metering Control Valve technology and adapts it for single-valve flow monitoring-only applications. The 133VF System major components are an X117D valve position transmitter, a differential or inlet and outlet pressure transmitters and a 131VF flow calculating module. All components are 24 VDC powered and weather protected to IP-68 submersible rating. The 131VF module, with standard DIN rail mounting, contains powerful mini-computer technology for calculating valve flow based on inputs from the sensors and using the appropriate flow curve for a particular Cla-Val valve. For increased accuracy the 131VF module uses third-party certified flow curves tested for this particular metering application. Valve differential pressure measurement can be located either at the valve inlet and outlet bosses or on pipe adjacent to the valve providing installation versatility in all applications and operating conditions.

For applications requiring flow measurement and remote set point control, see 133-01 Metering Valve catalog data sheet.

The Cla-Val Model 340-02/3640-02 Electronic Actuated Rate of Flow Control Valve combines the precise control of field proven Cla-Val hydraulic pilots and simple remote valve control. The Model 340-02/3640-02 valve controls flow by limiting flow to a preselected maximum rate (within a four to one ratio), regardless of changing line pressure. It is a hydraulically operated, pilot controlled, diaphragm actuated control valve. The valve uses a CDHS-33 actuated pilot control, consisting of a hydraulic pilot and integral controller that accepts a remote setpoint command input and makes set-point adjustments to the pilot. The recommended control method is simple remote set point change from an RTU (Remote Telemetry Unit) to the CDHS-33 where the 4-20 mA command signal is ranged to specific flow range of orifice plate and hydraulic pilot control components. Very accurate control can be achieved when span does not exceed 4:1 turndown. Since the CDHS-33 is pre-ranged to full spring range, some on-site calibration may be necessary when this control method is used. Free downloadable software is available from Cla-Val website for this purpose. The CDHS-33 can also accommodate control systems where the RTU compares flow rate transmitter signal to the remote set point command signal. The RTU adjusts the CDHS-33 with 4-20 mA command signal containing an adequate deadband to prevent actuator dithering after the two signals agree. Internal continuous electronic monitoring of actuator position results in virtually instantaneous position change with no backlash or dithering when control signal is changed. In the event of a power or control input failure, the CDHS-33 pilot remains in hydraulic control virtually assuring system stability under changing conditions. If check feature (“D”) is added, and pressure reversal occurs, the valve closes to prevent return flow.

Typical Applications

The valve is designed to be used with supervisor control systems (SCADA), having an isolated remote analog set-point output and a process variable flow transmitter input. It is also an effective solution for lowering costs associated with “confined space” requirements by eliminating the need for entry into valve structure for set-point adjustments and system information. Additional pilot controls, hydraulic and/or electronic, can be easily added to perform multiple control functions to fit exact system requirements.

The Cla-Val Model CDHS-33 Electronic Actuated Differential Pressure Pilot Control provides remote set-point adjustment and accurate differential pressure control for rate of flow control on Cla-Val 340 Series Control Valves. Remote set-point command signals can be from any SCADA-type control system using analog 4-20 mA signal or by contact closure for cc/ccw rotation. A precision orifice plate installed with valve creates differential pressure used for rate of flow control by the CDHS-33. Operating on 12 to 24 VDC and consuming very little power, it is an ideal control system for remote valve sites that may even be solar powered. Existing manually-set Cla-Val 40 Series Rate-of-Flow control valves can be retrofitted with CDHS-33 to add remote set-point control. Verification of differential pressure and corresponding flow rate may be sent to SCADA system from customer supplied differential pressure sensor attached to orifice plate.

The CDHS-33 consists of a hydraulic pilot and integral controller that accepts a 4-20 mA remote set-point and positions the pilot to maintain a maximum pressure differential at orifice plate and corresponding flow rate within preset limits. Pressure differential settings are linear between these settings. Special USB connector cable and free downloadable software can be used to change built-in electronic range limits for differential pressure and corresponding flow rate. Continuous internal monitoring of actuator position results in smooth transitions between pilot set-points with no backlash or dithering. When power or control input fail, the CDHS-33 pilot remains in automatic hydraulic control assuring system stability under all conditions.

Typical Applications

The CDHS-33 Is installed on Cla-Val 340 Series valves that maintain flow rate and require this flow to be changed from a remote location. It is also an effective solution for lowering costs associated with "confined space" requirements by eliminating the need for entry in valve structure for set-point adjustment. Additional pilot controls, hydraulic and/or electronic, are also available to perform multiple functions to fit exact system requirements.

The Cla-Val Model 350-02/3650-02 Electronic Actuated Pressure Sustaining Control Valve combines precise control of field proven Cla-Val hydraulic pilots and simple, remote valve control. The Model 35002/3650-02 is a hydraulically operated, pilot controlled, modulating valve designed to maintain constant upstream pressure within close limits. This valve can be used for pressure sustaining, back pressure or unloading functions in a by-pass system. The valve uses a CRL-33 pilot control, consisting of a hydraulic pilot and integral controller, that accepts a remote set-point command input and makes set-point adjustments to the pilot.

The recommended control method is simple remote set point change from an RTU (Remote Telemetry Unit) to the CRL-33 where the 4-20 mA command signal is ranged to specific pressure range. Very accurate control can be achieved when span does not exceed 100 psi. Since the CRL-33 is pre-ranged to the full spring range, some on-site calibration may be necessary when this control method is used. Free downloadable software is available from the Cla-Val website for this purpose. The CRL-33 can also accommodate control systems where the RTU compares pressure transmitter signal to the remote set point command signal. The RTU adjusts the CRL-33 with 4-20 mA command signal containing an adequate deadband to prevent actuator dithering after the two signals agree.

Internal continuous electronic monitoring of actuator position results in virtually instantaneous position change with no backlash or dithering when control signal is changed. In the event of a power or control input failure, the CRL-33 pilot remains in hydraulic control virtually assuring system stability under changing conditions. If check feature ("D") is added, and pressure reversal occurs, the valve closes to prevent return flow.

Product Dimensions Data:

For the 350-02 Main Valve (100-01) dimensions, see pages 17. For the 3560-02 Main Valve (100-20) dimensions, see pages 29.

Typical Applications

The valve is designed to be used with supervisory control systems (SCADA), having remote analog set-point output and process variable upstream pressure input. It is also an effective solution for lowering costs associated with “confined space” requirements by eliminating need for entry into valve structure for setpoint adjustment. Additional pilot controls, hydraulic and/or electronic, can be easily added to perform multiple control functions to fit exact system requirements.

Operating on 12 to 24 VDC and consuming very little power, it is an ideal control system for remote valve sites that may even be solar powered. Existing manually-set Cla-Val 50 Series Pressure Sustaining control valves can be retrofitted with CRL-33 to add remote set-point control of minimum inlet pressure. Verification of inlet pressure may be sent to SCADA system from customer supplied pressure sensor attached upstream of valve.

The CRL-33 consists of a hydraulic pilot and integral controller that accepts a 4-20 mA remote set-point and positions the pilot to maintain a minimum pressure at valve inlet within preset limits. Pressure settings are linear between these settings. Pressure settings are calibrated to the specific spring range of the control. Special USB connector cable and free downloadable software can be used to change this range if needed. Continuous internal monitoring of actuator position results in smooth transitions between pilot set-points with no backlash or dithering. Should power or control input fail, the CRL-33 pilot remains in automatic hydraulic control assuring system stability under all conditions.

Typical Applications

The CRL-33 is installed on Cla-Val 350 Series valves that maintain minimum upstream pressure by relieving excess pressure to lower zone and require this pressure setting to be changed from a remote location. It is also an effective solution for lowering costs associated with "confined space" requirements by eliminating the need for entry in valve structure for set point adjustment. Flow information can also be provided from the main valve, see E-133VF.

The Cla-Val Model 60-08/660-08 Pump Control Valve is a pilotoperated valve designed for installation on the discharge of booster pumps to eliminate pipeline surges caused by the starting and stopping of the pump.

The pump starts against a closed valve. When the pump is started, the solenoid control is energized and the valve begins to open slowly, gradually increasing line pressure to full pumping head. When the pump is signaled to shut-off, the solenoid control is de-energized and the valve begins to close slowly, gradually reducing flow while the pump continues to run. When the valve is closed, a limit switch assembly, which serves as an electrical interlock between the valve and the pump, releases the pump starter and the pump stops.

Should a power failure occur, a built-in, lift-type check valve closes the moment flow stops, preventing reverse flow regardless of solenoid or diaphragm assembly position.

The Cla-Val Model 60-32/660-32 Combination Pump Control and Back Pressure Valve is a pilot-operated control valve designed for booster pump discharge installation to eliminate pipeline surges caused by starting and stopping of pump and to provide adjustable back pressure on pump while it is running. The valve features a modified globe-design with diaphragm-actuation, and hydraulic operation for smooth, reliable automatic operation during pump starting and stopping. A built-in lift-type check feature automatically closes valve on electric power failure or any time pressure reversal occurs to protect pump from back spinning.

In operation, when pump is off, the pump control valve is closed by downstream system pressure. When pump is started, the solenoid control is energized and valve opens slowly to gradually increase pump flow and line pressure to desired back pressure setting for pumping conditions. When pump is signaled to shutoff, the solenoid control is de-energized and the valve begins to slowly close, gradually reducing flow while pump continues to run. When valve is closed, the included limit switch assembly turns off pump. Adjustable flow controls are included to easily regulate valve opening and closing speed to prevent surges. Using Cla-Val wiring diagram (see page 4) ensures safe electrical interlock control of pump and valve.

• Solenoid Control Can Be Operated Manually

• Proven Reliable Design

The Cla-Val Model 61-02/661-02 Deep Well Pump Control Valve is designed to protect pipelines from surges caused by the starting and stopping of deep well pumps. This is a hydraulically operated diaphragm valve which is controlled by a solenoid pilot valve. Separate adjustable flow control valves in the pilot system regulate the opening and closing rates. A limit switch on the valve stem serves as an electrical interlock between the valve and the pump motor.

The operation of the valve is completely automatic and controlled by the solenoid valve. With the pump off, the valve is wide open. When the pump is started, the solenoid is energized and the valve begins to close slowly, discharging air and the initial rush of sand and water from the pump column to atmosphere. As the valve closes the pump output is gradually diverted into the main line, preventing the development of a starting surge.

For the 61-02 Main Valve (100-02) dimensions, see pages 21. For the 661-02 Main Valve (100-21) dimensions, www.cla-val.com

Typical Installation

Install Model 61-02/661-02 valve as shown. Use a minimum of 1/2" tubing to connect operating pressure connection of the valve to the system side of check valve. Flexible conduit should be used for electrical connections to the solenoid control and the limit switch assembly. A Model 52-02/652-03 Surge Anticipator is recommended for power failure and surge protection.

When it is time to shut-off the pump, the solenoid is de-energized. The pump continues to run while the pump control valve opens slowly, diverting pump output to atmosphere. As pump pressure gradually decreases, the main line check valve closes slowly, preventing shock or slam during the pump stopping cycle. When the pump control valve is wide open, the limit switch assembly releases the pump starter and the pump stops.

Check Valve

• Simple Proven Design

• No-Slam Operation

• Drip-Tight Shut-Off

• No Packing Glands or Stuffing Boxes

• Easy to Install & Maintain

The Cla-Val Model 81-01/681-01 Check Valve is a hydraulically operated No-Slam Check Valve. This valve opens when the pressure at the inlet exceeds the discharge pressure. A gradual rate of opening prevents sudden opening surges. When a pressure reversal occurs the higher downstream pressure is applied to the cover chamber through the control tube lines, and the valve closes drip tight.

This valve is ideally suited for use where a positive shutoff is required. The rubber disc assures tight sealing even if the fluid contains grit or other small-size particles. The simple packless design insures reliable operation and freedom from leaks.

Note: The effectiveness of this valve is related to pipeline velocity. We recommend a maximum flow based on pipeline velocity of 6 feet per second. If pipeline velocities exceed 6 feet per second, consideration should be given to adding a Cla-Val Model 50-01 Pressure Relief Valve or a Cla-Val Model 52 Series Surge Control Valve to the system.

Inlet Outlet

Typical Applications

Smaller sizes of this valve are used in pilot control systems in Cla-Val Automatic Control valves. This valve can also be used in any piping system where one-way flow is desired.

Install on the discharge of booster pumps to prevent return flow into tank when pump is off. Relief valve as shown is good practice to minimize surges when pump stops.

For valve sizes larger than 3", use Model 81-02.
