Description

The CIa-VaI Model 100-01 Hytrol Valve is a main valve for CIa-VaI Automatic Control Valves. It is a hydraulically operated, diaphragm-actuated, globe or angle pattern valve.

This valve consists of three major components; body, diaphragm assembly, and cover. The diaphragm assembly is the only moving part. The diaphragm assembly uses a diaphragm of nylon fabric bonded with synthetic rubber. A synthetic rubber disc, contained on three and one half sides by a disc retainer and disc guide, forms a seal with the valve seat when pressure is applied above the diaphragm. The diaphragm assembly forms a sealed chamber in the upper portion of the valve, separating operating pressure from line pressure.

Installation

1. Before valve is installed, pipe lines should be flushed of all chips, scale and foreign matter.

2. It is recommended that either gate or block valves be installed on both ends of the 100-01 Hytrol Valve to facilitate isoIating the valve for preventive maintenance and repairs.

3. Place the valve in the line with flow through the valve in the direction indicated on the inlet nameplate. (See “Flow Direction” Section)

4. Allow sufficient room around valve to make adjustments and for disassembly.

5. CIa-VaI 100-01 Hytrol Valves operate with maximum effic iency when mounted in horizontal piping with the cover UP, however, other positions are acceptable. Due to size and weight of the cover and internal components of 8 inch and larger valves,

installation with the cover UP is advisable. This makes internal parts readily accessible for periodic inspection.

6. Caution must be taken in the installation of this valve to insure that galvanic and/or electrolytic action does not take place. The proper use of dielectric fittings and gaskets are required in all systems using dissimilar metals.

7. If a pilot control system is installed on the 100-01 Hytrol Valve, use care to prevent damage. If it is necessary to remove fittings or components, be sure they are kept clean and replaced exactly as they were.

8. After the valve is installed and the system is first pressurized, vent air from the cover chamber and pilot system tubing by loosening fittings at all high points.

Tight Closing Operation

When pressure from the valve inlet (or an equivalent independent operating pressure) is applied to the diaphragm chamber the valve closes drip-tight.

Full Open Operation

When pressure in diaphragm chamber is relieved to a zone of lower pressure (usually atmosphere) the line pressure (5 psi Min.) at the valve inlet opens the valve.

Modulating Action

Valve modulates when diaphragm pressure is held at an intermediate point between inlet and discharge pressure. With the use of a Cla-Val. "modulating control," which reacts to line pressure changes, the pressure above the diaphragm is varied, allowing the valve to throttle and compensate for the change.

Flow Direction

The flow through the 100-01 Hytrol Valve can be in one of two directions. When flow is “up-and-over the seat,” it is in “normal” flow and the valve will fail in the open position. When flow is “overthe seat-and down,” it is in “reverse” flow and the valve will fail in the closed position. There are no permanent flow arrow markings.

The valve must be installed according to nameplate data.

Troubleshooting

The following troubleshooting information deals strictly with the Model 100-01 Hytrol Valve. This assumes that all other components of the pilot control system have been checked out and are in proper working condition. (See appropriate sections in Technical Manual for complete valve).

Three Checks

The 100-01 Hytrol Valve has only one moving part (the diaphragm and disc assembly). So, there are only three major types of problems to be considered.

First: Valve is stuck - that is, the diaphragm assembly is not free to move through a full stroke either from open to close or vice versa.

Second: Valve is free to move and can’t close because of a worn out diaphragm.

Third: Valve leaks even though it is free to move and the diaphragm isn’t leaking.

Closed isolation valves in control system, or in main line.

Lack of cover chamber pressure.

Diaphragm damaged. (See Diaphragm Check.)

Diaphragm assembly inoperative. Corrosion or excessive scale build up on valve stem. (See Freedom of Movement Check)

Mechanical obstruction. Object lodged in valve. (See Freedom of Movement Check)

Worn disc. (See Tight Sealing Check)

Badly scored seat. (See Tight Sealing Check)

Closed upstream and/or downstream isolation valves in main line.

Insufficient line pressure.

Diaphragm assembly inoperative. Corrosion or excessive buildup on valve stem. (See Freedom of Movement Check)

Diaphragm damaged. (For valves in "reverse flow" only)

After checking out probable causes and remedies, the following three checks can be used to diagnose the nature of the problem before maintenance is started. They must be done in the order shown.

Open Isolation valves.

Check upstream pressure, pilot system, strainer, tubing, valves, or needle valves for obstruction.

Replace diaphragm.

Clean and polish stem. Inspect and replace any damaged or badly eroded part.

Remove obstruction.

Replace disc.

Replace seat.

Open isolation valves.

Check upstream pressure. (Minimum 5 psi flowing line pressure differential.)

Clean and polish stem. Inspect and replace any damaged or badly eroded part.

Replace diaphragm.

Fails to Close

Fails to Open

CAUTION: Care should be taken when doing the troubleshooting checks on the 100-01 Hytrol Valve. These checks do require the valve to open fully. This will either allow a high flow rate through the valve, or the downstream pressure will quickly increase to the inlet pressure. In some cases, this can be very harmful. Where this is the case, and there are no block valves in the system to protect the downstream piping, it should be realized that the valve cannot be serviced under pressure. Steps should be taken to remedy this situation before proceeding any further.

SYMPTOM PROBABLE CAUSE REMEDY

Recommended Tools

1. Three pressure gauges with ranges suitable to the installation to be put at Hytrol inlet, outlet and cover connections.

2. Cla-Val Model X101 Valve Position Indicator. This provides visual indication of valve position without disassembly of valve.

3. Other items are: suitable hand tools such as screwdrivers, wrenches, etc. soft jawed (brass or aluminum) vise, 400 grit wet or dry sandpaper and water for cleaning.

All trouble shooting is possible without removing the valve from the line or removing the cover. It is highly recommended to permanently install a Model X101 Valve Position Indicator and three gauges in unused Hytrol inlet, outlet and cover connections.

Diaphragm Check (#1 )

1. Shut off pressure to the Hytrol Valve by slowly closing upstream and downstream isolation valves. SEE CAUTION.

2. Disconnect or close all pilot control lines to the valve cover and

leave only one fitting in highest point of cover open to atmosphere.

3.With the cover vented to atmosphere, slowly open upstream isolation valve to allow some pressure into the Hytrol Valve body. Observe the open cover tapping for signs of continuous flow. It is not necessary to fully open isolating valve. Volume in cover chamber capacity chart will be displaced as valve moves to open position. Allow sufficient time for diaphragm assembly to shift positions. If there is no continuous flow, you can be quite certain the diaphragm is sound and the diaphragm assembly is tight. If the fluid appears to flow continuously this is a good reason to believe the diaphragm is either damaged or it is loose on the stem. In either case, this is sufficient cause to remove the valve cover and investigate the leakage. (See “Maintenance” Section for procedure.)

Freedom of Movement Check (#2)

4. Determining the Hytrol Valve’s freedom of movement can be

done by one of two methods.

5. For most valves it can be done after completing Diaphragm Check (Steps 1, 2, and 3). SEE CAUTION. At the end of step 3 the valve should be fully open.

6. If the valve has a Cla-Val X101 Position Indicator, observe the indicator to see that the valve opens wide. Mark the point of maximum opening.

7. Re-connect enough of the control system to permit the application of inlet pressure to the cover. Open pilot system cock so pressure flows from the inlet into the cover.

8. While pressure is building up in the cover, the valve should close smoothly. There is a hesitation in every Hytrol Valve closure, which can be mistaken for a mechanical bind. The stem will appear to stop moving very briefly before going to the closed position. This slight pause is caused by the diaphragm flexing at a particular point in the valve’s travel and is not caused by a mechanical bind.

9. When closed, a mark should be made on the X101 Valve position indicator corresponding to the “closed” position. The distance between the two marks should be approximately the stem travel shown in chart.

10. If the stroke is different than that shown in stem travel chart this is a good reason to believe something is mechanically restricting the stroke of the valve at one end of its travel. If the flow does not stop through the valve when in the indicated “closed” position, the obstruction probably is between the disc and the seat. If the flow does stop, then the obstruction is more likely in the cover. In either case, the cover must be removed, and the obstruction located and removed. The stem should also be checked for scale buildup. (See “Maintenance, section for procedure.)

11. For valves 6” and smaller, the Hytrol Valve’s freedom of movement check can also be done after all pressure is removed from the valve. SEE CAUTION. After closing inlet and outlet isolation valves and bleeding pressure from the valve, check that the cover chamber and the body are temporarily vented to atmosphere. Insert fabricated tool into threaded hole in top of valve stem, and lift the diaphragm assembly manually. Note any roughness. The diaphragm assembly should move smoothly throughout entire valve stroke. The tool is fabricated from rod that is threaded on one end to fit valve stem and has a “T” bar handle of some kind on the other end for easy gripping. (See chart in Step 4 of “Disassembly” Section.)

12. Place marks on this diaphragm assembly lifting tool when the valve is closed and when manually positioned open. The distance between the two marks should be approximately the stem travel shown in stem travel chart. If the stroke is different than that shown, there is a good reason to believe something is mechanically restricting the stroke of the valve. The cover must be removed, and the obstruction located and removed. The stem should also be checked for scale build-up. (See “Maintenance” Section for procedure.)

Tight Sealing Check (#3)

13. Test for seat leakage after completing checks #1 & #2 (Steps

1 to 12). SEE CAUTION. Close the isolation valve downstream of the Hytrol Valve. Apply inlet pressure to the cover of the valve, wait until it closes. Install a pressure gauge between the two closed valves using one of the two ports in the outlet side of the Hytrol. Watch the pressure gauge. If the pressure begins to climb, then either the downstream isolation valve is permitting pressure to creep back, or the Hytrol is allowing pressure to go through it. Usually the pressure at the Hytrol inlet will be higher than on the isolation valve discharge, so if the pressure goes up to the inlet pressure, you can be sure the Hytrol is leaking. Install another gauge downstream of isolating valve. If the pressure between the valves only goes up to the pressure on the isolation valve discharge, the Hytrol Valve is holding tight, and it was just the isolation valve leaking.

Maintenance

Preventative Maintenance

The Cla-Val Co. Model 100-01 Hytrol Valve requires no lubrication or packing and a minimum of maintenance. However, a periodic inspection schedule should be established to determine how the operating conditions of the system are affecting the valve. The effect of these actions must be determined by inspection.

Disassembly

Inspection or maintenance can be accomplished without removing the valve from the line. Repair kits with new diaphragm and disc are recommended to be on hand before work begins.

WARNING: Maintenance personnel can be injured and equipment damaged if disassembly is attempted with pressure in the valve. SEE

CAUTION.

1. Close upstream and downstream isolation valves and independ- ent operating pressure when used to shut off all pressure to the

valve.

2. Loosen tube fittings in the pilot system to remove pressure from valve body and cover chamber. After pressure has been released from the valve, use care to remove the controls and tubing. Note and sketch position of tubing and controls for re-assembly. The schematic in front of the Technical Manual can be used as a guide when reassembling pilot system.

3. Remove cover nuts and remove cover. If the valve has been in service for any length of time, chances are the cover will have to be loosened by driving upward along the edge of the cover with a dull cold chisel.

On 6” and smaller valves block and tackle or a power hoist can be used to lift valve cover by inserting proper size eye bolt in place of the center cover plug. on 8” and larger valves there are 4 holes (5/8” — 11 size) where jacking screws and/or eye bolts may be inserted for lifting purposes. Pull cover straight up to keep from damaging the integral seat bearing and stem.

4. Remove the diaphragm and disc assembly from the valve body. With smaller valves this can be accomplished by hand by pulling

straight up on the stem so as not to damage the seat bearing.

On large valves, an eye bolt of proper size can be installed in the stem and the diaphragm assembly can be then lifted with a block and tackle or power hoist. Take care not to damage the stem or bearings. The valve won't work if these are damaged.

5. The next item to remove is the stem nut. Examine the stem threads above the nut for signs of mineral deposits or corrosion. If the threads are not clean, use a wire brush to remove as much of the residue as possible. Attach a good fitting wrench to the nut and give it a sharp “rap” rather than a steady pull. Usually several blows are sufficient to loosen the nut for further removal. On the smaller valves, the entire diaphragm assembly can be held by the stem in a vise equipped with soft brass jaws before removing the stem nut.

The use of a pipe wrench or a vise without soft brass jaws scars the fine finish on the stem. No amount of careful dressing can restore the stem to its original condition. Damage to the finish of the stem can cause the stem to bind in the bearings and the valve will not open or close.

6. After the stem nut has been removed, the diaphragm assembly breaks down into its component parts. Removal of the disc from the disc retainer can be a problem if the valve has been in service for a long time. Using two screwdrivers inserted along the outside edge of the disc usually will accomplish its removal. Care should be taken to preserve the spacer washers in water, particularly if no new ones are available for re-assembly.

7. The only part left in the valve body is the seat which ordinarily does not require removal. Careful cleaning and polishing of inside and outside surfaces with 400 wet/dry sandpaper will usually restore the seat’s sharp edge. If, however, it is badly worn and replacement is necessary, it can be easily removed.

Seats in valve sizes 1 1/4” through 6” are threaded into the valve body. They can be removed with accessory X109 Seat Removing Tool available from the factory. On 8” and larger valves, the seat is held in place by flat head machine screws. Use a tight-fitting, long shank screwdriver to prevent damage to seat screws. If upon removal of the screws the seat cannot be lifted out, it will be necessary to use a piece of angle or channel iron with a hole drilled in the center. Place it across the body so a long stud can be inserted through the center hole in the seat and the hole in the angle iron. By tightening the nut a uniform upward force is exerted on the seat for removal.

NOTE: Do not lift up on the end of the angle iron as this may force the integral bearing out of alignment, causing the stem to bind.

Lime Deposits

One of the easiest ways to remove lime deposits from the valve stem or other metal parts is to dip them in a 5-percent muriatic acid solution just long enough for the deposit to dissolve. This will remove most of the common types of deposits. CAUTlON: USE EXTREME CARE WHEN HANDLING ACID. Rinse parts in water before handling. If the deposit is not removed by acid, then a fine grit (400) wet or dry sandpaper can be used with water.

Reassembly

1. Reassembly is the reverse of the disassembly procedure. If a

new disc has been installed, it may require a different number of spacer washers to obtain the right amount of “grip” on the disc. When the diaphragm assembly has been tightened to a point where the diaphragm cannot be twisted, the disc should be compressed very slightly by the disc guide. Excessive compression should be avoided. Use just enough spacer washers to hold the disc firmly without noticeable compression.

2. MAKE SURE THE STEM NUT IS VERY TIGHT. Attach a good fitting wrench to the nut and give it a sharp “rap” rather than a steady pull. Usually several blows are sufficient to tighten the stem nut for final tightening. Failure to do so could allow the diaphragm to pull loose and tear when subjected to pressure.

Test Procedure After Valve Assembly

There are a few simple tests which can be made in the field to make sure the Hytrol Valve has been assembled properly. Do these before installing pilot system and returning valve to service. These are similar to the three troubleshooting tests.

1. Check the diaphragm assembly for freedom of movement after all pressure is removed from the valve. SEE CAUTlON. Insert fabricated tool into threaded hole in top of valve stem, and lift the diaphragm assembly manually. Note any roughness, sticking or grabbing. The diaphragm assembly should move smoothly throughout entire valve stroke. The tool is fabricated from rod that is threaded on one end to fit valve stem (See chart in Step 4 of “Disassembly” section.) and has a “T” Bar handle of some kind on the other end for easy gripping.

Place marks on this diaphragm assembly lifting tool when the valve is closed and when manually positioned open. The distance between the two marks should be approximately the stem travel shown in stem travel chart. (See “Freedom of Movement Check” section.) If the stroke is different than that shown, there is a good reason to believe something is mechanically restricting the stroke of the valve. The cover must be removed, the obstruction located and removed. (See “Maintenance” Section for procedure.)

Inspection of Parts

After the valve has been disassembled, each part should be examined carefully for signs of wear, corrosion, or any other abnormal condition. Usually, it is a good idea to replace the rubber parts (diaphragm and disc) unless they are free of signs of wear. These are available in a repair kit. Any other parts which appear doubtful should be replaced. WHEN ORDERlNG PARTS, BE SURE TO GIVE COMPLETE NAMEPLATE DATA, ITEM NUMBER AND DESCRlPTlON.

NOTE: If a new disc isn’t available, the existing disc can be turned over, exposing the unused surface for contact with the seat. The disc should be replaced as soon as practical.

3. Carefully install the diaphragm assembly by lowering the stem through the seat bearing. Take care not to damage the stem or bearing. Line up the diaphragm holes with the stud or bolt holes on the body. on larger valves with studs, it may be necessary to hold the diaphragm assembly up part way while putting the diaphragm over the studs.

4. Put spring in place and replace cover. Make sure diaphragm is Iying smooth under the cover.

5. Tighten cover nuts firmly using a cross-over pattern until all nuts are tight.

6. Test Hytrol Valve before re-installing pilot valve system.

Due to the weight of the diaphragm assembly this procedure is not possible on valves 8” and larger. on these valves, the same determination can be made by carefully introducing a low pressure-less than five psi) into the valve body with the cover vented. SEE CAUTION. Looking in cover center hole see the diaphragm assembly lift easily without hesitation, and then settle back easily when the pressure is removed.

2. To check the valve for drip-tight closure, a line should be connected from the inlet to the cover, and pressure applied at the inlet of the valve. If properly assembled, the valve should hold tight with as low as ten PSI at the inlet. See “Tight Sealing Check” section.)

3. With the line connected from the inlet to the cover, apply full working pressure to the inlet. Check all around the cover for any leaks. Re-tighten cover nuts if necessary to stop leaks past the diaphragm.

4. Remove pressure, then re-install the pilot system and tubing exactly as it was prior to removal. Bleed air from all high

points.

5. Follow steps under “Start-Up and Adjustment” Section in

Technical Manual for returning complete valve back to service

Description 100-01 Hytrol Valve

The CIa-VaI Model 100-01 Hytrol Valve is a main valve for

CIa-VaI Automatic Control Valves. It is a hydraulically operated,

diaphragm-actuated, globe or angle pattern valve.

This valve consists of three major components; body, diaphragm

assembly, and cover. The diaphragm assembly is the only

moving part. The diaphragm assembly uses a diaphragm of nylon

fabric bonded with synthetic rubber. A synthetic rubber disc,

contained on three and one half sides by a disc retainer and disc

guide, forms a seal with the valve seat when pressure is applied

above the diaphragm. The diaphragm assembly forms a sealed

chamber in the upper portion of the valve, separating operating

pressure from line pressure.

Description 100-20 600 Series Hytrol Valve

The CIa-VaI Model 100-20 Hytrol Valve (600 Series main valve)

have only one part -the body- that is different from standard 100

Series Cla-Val main valve parts. The remaining parts of the 600

series main valve are standard Cla-Val main valve parts. All serv-

ice and maintenance information for the standard 100 Series

main valves also apply to the 600 series main valves.

The most important thing to remember when ordering main

valve repair kits and replacement parts, except for the body, all

other parts are going to be for a smaller size main valve. Cla-

Val identifies main valve parts with the flange size of the stan-

dard 100 Series main valve. Refer to the "Main Valve Sizes”

100-01 Hytrol Main Valve Assembly

UNDERSTANDING THE 600 SERIES VALVES

In 1987, Cla-Val introduced the Model 100-20 Hytrol as the basic main valve for the 600 Series of automatic control valves. To identify all new valves using the 100-20 Hytrol, an existing catalog number is modified. Making a 600 Series catalog number is simply done by using a "6" in front of the two digit catalog numbers or replacing the "2" with a "6" in three digit catalog numbers. Current schematics reflect both catalog numbers together separated by a slash ( i.e. - 90-01/690-01, 58-02/658-02, 21001/610-01, etc). Since these two valves 'share' the same catalog number and schematic, they provide the same function in a system. The only difference between the two valves is the relative capacity of the two main valve series.

The 100-01 Hytrol is the basic main valve for Cla-Val automatic control valves. This valve is the current version of the Clayton Hytrol valve design originated in 1936. The 100-01 Hytrol is designed as a full flow area valve. This means that the inlet, seat and outlet openings are the same size. Thus, the pressure drop is kept to a minimum for this globe style design.

The 100-20 Hytrol valve has all of the basic features and advantages of the original 100-01 Hytrol. Only one part has been changed - the body. It is designed with different size inlet, seat and outlet openings. The 100-20 Hytrol has inlet and outlet flanges one valve size larger than the seat opening size. This results in what is sometimes called a ''reduced port' main valve. For example, a 4" 100-20 valve has a 3" seat. Note: valve size is always determined by the flange size. The following chart compares the 100-01 and the 100-20 main valves.

MODEL

INSTALLATION / OPERATION / MAINTENANCE

SERVICE AND MAINTENANCE OF 600 SERIES VALVES

The 600 series main valves have only one part -the body- that is different from standard 100 Series Cla-Val main valve parts. The remaining parts of the 600 series main valve are standard ClaVal main valve parts. All service and maintenance information for the standard 100 Series main valves in this manual also apply to the 600 series main valves.

The most important thing to remember when ordering main valve repair kits and replacement parts, except for the body, all other parts are going to be for a smaller size main valve. Cla-Val identifies main valve parts with the flange size of the standard 100 Series main valve. Refer to the "Main Valve Sizes Comparison" chart. For example, if you are servicing a 6" 100-20 Hytrol and needed a repair kit, you would order a repair kit for a 4" 100-01 Hytrol. This kit is also suitable for a 6" 100-20 Hytrol. Complete Technical Manuals include a repair kit data sheet N-RK that shows this relationship.

When you order repair parts, it is a good idea to include valve nameplate data (size, catalog number, and part number) and description of the parts desired. Do this to be sure parts will fit the valve you are working on and not be too big for it. Pilot controls and repair kits maintenance information remain the same for 100 or 600 Series valves.

Cla-Val Main Valves

Catalog Number

The 100-20 Hytrol is available only in ductile iron, 150 and 300 pressure class, and Bronze trim standard. Available extra cost main valve options include stainless steel trim, epoxy coating, Dura-Kleen stem, Delrin sleeved stem, and high temperature rubber parts.

DESCRIPTION

Bulletin 8210’s are 2-way, normally closed internal pilot operated solenoid valves. Valve bodies and bonnets are of brass construction. Standard valves have a General Purpose, NEMA Type 1 Solenoid Enclosure. Bulletin 8211’s are the same as Bulletin 8210’s except the solenoids are equipped with an enclosure which is designed to meet NEMA Type 4, Watertight, NEMA Type 7 (C or D) Hazardous Locations - Class 1, Group C or D and NEMA Type 9 (E, For G) Hazardous Locations - Class 2, Groups E, F or G. The Explosion-Proof/Watertight Solenoid Enclosures are shown on separate sheets of installation and Maintenance Instructions, Form Numbers V-5380 and V-5391.

OPERATION

Normally Closed: Valve is closed when solenoid is de-energized and opens when solenoid is energized.

MANUAL OPERATOR

(Optional) Valves with Suffix ‘MO’ in the catalog number are provided with a manual operator which allows manual operation when desired or during an interruption of electrical power. To operate valve manually, push in knurled cap and rotate clockwise 180° Disengage manual operator by rotating knurled cap counterclockwise 180° before operating electrically.

MANUAL OPERATOR LOCATION

(Refer to Figures 1 and 3) Manual operator (when shipped from factory) will be located over the valve outlet. Manual operator may be relocated at 90° increments by rotating valve bonnet. Remove bonnet screws (4) and rotate valve bonnet with solenoid to desired position. Replace bonnet screws (4) and torque in a crisscross manner to 110 ± 10 inch pounds. If valve is installed in the system and is operational, proceed in the following manner:

WARNING:

Depressurize valve and turn off electrical

power supply.

1. Remove retaining cap or clip and slip the entire solenoid enclosure off the solenoid base sub-assembly.

CAUTION:

When metal retaining clip

disengages, it will spring upwards.

2. Remove bonnet screws (4) and rotate valve bonnet to desired position.

3. Replace bonnet screws (4) and torque in a crisscross manner to 110 ± 10 inch pounds. Replace solenoid enclosure and retaining clip or cap.

INSTALLATION

Check nameplate for correct catalog number, pressure, voltage and service.

TEMPERATURE LIMITATIONS

For maximum valve ambient and fluid temperatures, refer to chart. The temperature limitations listed are for UL applications. For non-UL applications, higher ambient and fluid temperature limitations are available. Consult factory, Check catalog number on nameplate to determine maximum temperatures.

POSITIONING/MOUNTING

This valve is designed to perform properly when mounted in any position. However, for optimum life and performance, the solenoid should be mounted vertical and upright so as to reduce the possibility of foreign matter accumulating in the core tube area. For mounting bracket (optional feature) dimensions, refer to Figure 2.

PIPING

Connect piping to valve according to markings on valve body. Apply pipe compound sparingly to male pipe threads only; if applied to valve threads, it may enter the valve and cause operational difficulty. Pipe strain should be avoided by proper support and alignment of piping. When tightening the pipe, do not use valve as a lever, Wrenches applied to valve body or piping are to be located as close as possible to connection point.

IMPORTANT:

For the protection of the solenoid valve, install a strainer or filter suitable for the service involved in the inlet side as close to the valve as possible. Periodic cleaning Is required depending on the service conditions. See Bulletins 8600, 8601 and 8602 for strainers.

WIRING

Wiring must comply with Local and National Electrical Codes. Housings for all solenoids are provided with connections for 1/2 inch conduit. The general purpose solenoid enclosure may be rotated to facilitate wiring by removing the retaining cap or clip.

CAUTION:

When metal retaining clip disengages, it will spring upwards. Rotate to desired position. Replace retaining cap or clip before operating.

NOTE:

Alternating Current (A-C) and Direct Current (D-C) solenoids are built differently. To convert from one to the other, It Is necessary to change the complete solenoid including the solenoid base sub-assembly and core assembly.

SOLENOID TEMPERATURE

Standard catalog valves are supplied with coils designed for continuous duty service. When the solenoid is energized for a long period, the solenoid enclosure becomes hot and can be touched with the hand only for an instant. This is a safe operating temperature. Any excessive heating will be indicated by the smoke and odor of burning coil insulation.

MAINTENANCE

WARNING:

Turn off electrical power supply and depressurize valve before making repairs. It Is not necessary to remove the valve from the pipe line for repairs.

CLEANING

A periodic cleaning of all solenoid valves is desirable. The time between cleanings will vary, depending on media and service conditions. In general, if the voltage to the coil is correct, sluggish valve operation, excessive leakage or noise will indicate that cleaning is required.

PREVENTIVE MAINTENANCE

1. Keep the medium flowing through the valve as free from dirt and foreign material as possible.

2. While in service, operate the valve at least once a month to insure proper opening and closing.

3. Periodic inspection (depending on media and service conditions) of internal valve parts for damage or excessive wear is recommended. Thoroughly clean all parts, Replace any parts that are worn or damaged.

The X46 Flow Clean strainer operates on a velocity principle utilizing the circular "air foil" section to make it self cleaning. Impingement of particles is on the "leading edge" only. The low pressure area on the downstream side of the screen prevents foreign particles from clogging the screen. There is also a scouring action, due to eddy currents, which keeps most of the screen area clean.

INSPECTION

Inspect internal and external threads for damage or evidence of cross-threading. Check inner and outer screens for clogging, embedded foreign particles, breaks, cracks, corrosion, fatigue, and other signs of damage.

CLEANING

After inspection, cleaning of the X46 can begin. Water service usually will produce mineral or lime deposits on metal parts in contact with water. These deposits can be cleaned by dipping X46 in a 5-percent muriatic acid solution just long enough for deposit to dissolve. This will remove most of the common types of deposits. Caution: use extreme care when handling acid. If the deposit is not removed by acid, then a fine grit (400) wet or dry sandpaper can be used with water. Rinse parts in water before handling. An appropriate solvent can clean parts used in fueling service. Dry with compressed air or a clean, lint-free cloth. Protect from damage and dust until reassembled.

REPLACEMENT

If there is any sign of damage, or if there is the slightest doubt that the Model X46 Flow Clean Strainer may not afford completely satisfactory operation, replace it. Use Inspection steps as a guide. Neither inner screen, outer screen, nor housing is furnished as a replacement part. Replace Model X46 Flow Clean Strainer as a complete unit.

When ordering replacement Flow-Clean Strainers, it is important to determine pipe size of the tapped hole into which the strainer will be inserted (refer to column A or F), and the size of the external connection (refer to column B or G).

When Ordering, Please Specify:

Flow Control

MODEL

N-CV (R-3/2011)

DESCRIPTION

The Cla-Val Model CV Flow Control is a simply-designed, spring-loaded check valve. Rate of flow is full flow in one direction and restricted in other direction. Flow is adjustable in the restricted direction. It is intended for use in conjunction with a pilot control system on a Cla-Val Automatic Control Valve.

OPERATION

The CV Flow Control permits full flow from port A to B, and restricted flow in the reverse direction. Flow from port A to B lifts the disc from seat, permitting full flow. Flow in the reverse direction seats the disc, causing fluid to pass through the clearance between the stem and the disc. This clearance can be increased, thereby increasing the restricted flow, by screwing the stem out, or counter-clockwise. Turning the stem in, or clockwise reduces the clearance between the stem and the disc, thereby reducing the restricted flow.’

INSTALLATION

Install the CV Flow Control as shown in the valve schematic All connections must be tight to prevent leakage.

DISASSEMBLY

Follow the sequence of the item numbers assigned to the parts in the cross sectional illustration for recommended order of disassembly.

Use a scriber, or similar sharp-pointed tool to remove O-ring from the stem.

INSPECTION

Inspect all threads for damage or evidence of cross- threading. Check mating surface of seat and valve disc for excessive scoring or embedded foreign particles. Check spring for visible distortion, cracks and breaks. Inspect all parts for damage, corrosion and cleanliness.

CLEANING

After disassembly and inspection, cleaning of the parts can begin. Water service usually will produce mineral or lime deposits on metal parts in contact with water. These deposits can be cleaned by dipping the parts in a 5-percent muriatic acid solution just long enough for deposits to dissolve. This will remove most of the common types of deposits. Caution: use extreme care when handling acid. If the deposit is not removed by acid, then a fine grit (400) wet or dry sandpaper can be used with water. Rinse parts in water before handling. An appropriate solvent can clean parts used in fueling service. Dry with compressed air or a clean, lint-free cloth. Protect from damage and dust until reassembled.

REPAIR AND REPLACEMENT

Minor nicks and scratches may be polished out using a fine grade of emery or crocus cloth; replace parts if scratches cannot be removed.

Replace O-ring packing and gasket each time CV Flow Control is overhauled.

Replace all parts which are defective. Replace any parts which create the slightest doubt that they will not afford completely satisfactory operation. Use Inspection steps as a guide.

REASSEMBLY

Reassembly is the reverse of disassembly; no special tools are required.

TEST PROCEDURE

No testing of the flow Control is required prior to reassembly to the pilot control system on Cla-Val Main Valve.

WIRING

Loosen jam nut holding transmitter and bracket to adapter when connecting transmitter to field wiring. Tighten jam nut after connections and adjustments are made.

Use good field wiring practices for low voltage DC analog instrumentation wiring (suggest minimum of 18-gauge multistrand wire). Avoid potential ground loops. Calibration of transmitter should be done with a temporary hookup of test equipment before final wiring connections are made.

Units with NEMA 6, IP-68 enclosures have permanently attached 8' shielded cable leads. Use Red wire for positive and Black wire for negative.

Units before Feb. 2000 have NEMA 6 enclosure with MS3102E14S-6PAmphenol plug and socket for attaching leads. Use "A" contact for positive and "B" contact for negative.

For best noise immunity, use twisted pair shielded cable to connect field wiring to the transmitter. The shield of the cable should be open at the transducer and grounded at the other end. Units with permanently attached cable are supplied with shield open inside transmitter.

CALIBRATION

1. When properly adjusted, the transmitter will have the valve closed position within 0% to 30% of total transmitter range and the valve open position within 80% to 100% of total transmitter range. At valve closed position the transmitter will have a 4 mA output and at fully open position the transmitter will have a 20 mA output.

IMPORTANT CAUTION

: The transmitter wire rope mechanism is

spring loaded to retract and can be damaged by a sudden release

of the wire rope. Use care to insure that it is returned to the transmitter very slowly during start up and operation. This damage may not be covered by warranty.

2. You will need the following tools to calibrate and align the X117D: A.) A small flat blade screwdriver (.105 Max. width x .023” max. thickness) with non-metallic handle to fit the span and null potentiometer B.) A 4-20 mA calibration/tester or multiamp-tester/meter or some means of measuring the 4-20 mA transmitter output C.) Hand tools to adjust and tighten X117D assembly during calibration

3. Preliminary mechanical settings. (Refer to Drawing No. 200000)

Be sure that the valve is in the fully closed position. See Technical Manual for the main valve for information on this. Check that line isolation or block valves are closed.

Adjust Nut Coupler (9) up or down on stem until gap between wire rope end and transmitter housing is according to table (below). The Hex Coupler (10) is used to tighten nut coupler to stem. A minimum gap is required, see Reference Table. (Refer to Drawing No. 200000)

Long threaded end of Hex Coupler (10) has two hex nuts (11) for adjusting position of end of wire rope directly over the opening in the top of the transmitter. Use one hex nut on each side of the wire rope end. Wire rope should go vertically up and down without noticeable angle from vertical.

4. Temporarily connect calibration equipment (milliamp meter and

power supply or portable instrumentation tester) to transmitter wiring. Calculate total loop resistance to determine minimum load resistor. See OPERATION

section. Remove two calibration cover

screws found on housing end.

Valve Position Transmitter

X117D

DESCRIPTION

The Cla-Val Model X117D Valve Position Transmitter is designed to provide analog signal (4 - 20 mA, 2 wire) output of valve position for Cla-Val Main Valves. A stem extension is fitted to the main valve stem with the position transmitter mechanically linked to it. The valve stem is mechanically linked to the electronics for an output signal that is in direct proportion to valve position. Provisions are made for bleeding air from valve cover through a small bleed screw and washer located on adapter.

INSTALLATION

Normally, the X117D is supplied mounted on the Cla-Val main valve. If X117D has not been installed at factory, then install stem, adapter, mounting bracket with transmitter (in that order) as shown on drawing No. 200000.

MODEL

INSTALLATION / OPERATION / MAINTENANCE

OPERATION

The signal from the position sensing linkage mechanism is converted to a two-wire 4 to 20 mA current output appearing at the output terminals. The excitation voltage ranges from 12 to 35 Volts DC. The minimum supply voltage is a function of total loop resistance. It may be calculated using the formula:

V(min) = (0.02 x Load Resistance) + 12 VDC

N-X117D (R-3/2011)

Refer to calibration equipment and adjust transmitter potentiometer marked “NULL” until the meter reads 4 mA. A clockwise turn increases output. Use care in adjusting the potentiometer while turning the screwdriver.

5. For the most accurate calibration it is necessary to open valve fully. CAUTION: This will either allow a high flow rate through the valve, or the downstream pressure will quickly increase to the inlet pressure. In some cases, this can be very harmful. Where this is the case, and there are no block valves in the system to protect the downstream piping, it should be realized that steps should be taken to remedy this situation before proceeding further. Normally, block valves are to be used to protect downstream piping while the valve is in the open position. Close downstream block valve. Vent cover chamber to atmosphere. Slightly open inlet block valve. Allow valve to open while fluid is vented from cover chamber. When flow stops valve is in the fully open position. Note: continuous leakage from cover chamber could mean additional troubleshooting of the main valve or pilot system must be done.

6. With valve in fully open position, inspect position of wire rope and nut coupler. (See Step 3). Adjust if necessary.

Refer to calibration equipment (see Step 4) and adjust potentiometer marked “SPAN” until the meter reads 20 mA. A clockwise turn increases output. Use care in adjusting the potentiometer while turning the screwdriver.

7. There is some interplay between:

1.) the “span” and “null” settings,

2.) the 4 to 20 mA signal and,

3.) the actual valve open and closed positions. Repeat steps 4-6 above. Cycle valve from open to closed positions and check settings as necessary to achieve desired valve position signal accuracy.

8. Remove all calibration equipment and attach permanent wiring. Recheck wiring and output signals at remote location. See Wiring section. Reinstall two cover screws on housing. Recheck and tighten all fasteners. Bleed air from main valve cover through small bleed screw and washer located on one wrench flat of adapter.

MAINTENANCE

The X117D is constructed of durable materials which normally requiring no lubrication or periodic maintenance. The two ‘O’ rings (2) (p/n 00951E) in the adapter (5) that seal against the stainless steel actuating stem (1) will need replacement if signs of leakage at the stem occur.

The Cla-Val 131VC-1 Electronic Control System is designed to achieve unprecedented valve control accuracy and stability. Ideal for remote valve control, the 131VC-1 Electronic Control System provides the interface between SCADA system computers and hydraulic control valves sites.

Electronic Control of Hydraulic Valves

The 131VC-1 Electronic Control System is designed to work in conjunction with Cla-Val 131 Series hydraulic control valves— a combination that takes advantage of the simplicity of hydraulic valve operation and the control possibilities available with electronics.

The 131VC-1 Electronic Control System receives transmitted signals and activates dual solenoid pilots on the hydraulic control valve. These pilots direct hydraulic pressure within the system to position and regulate the valve. By continuously comparing system conditions to the programmed set-point, the system is automatically maintained at the desired value.

Additional important control features, unique to this type of valve control, are offered as standard. They are designed for user friendly operation and system safety and are addressed in this brochure.

Key Advantages

• Proven reliable hydraulic control valve

• Low electric power requirement

• Solid state electronic components

1. Set-Point Command

Set-point command is received from a remote location or entered via the key pad into the Electronic Valve Controller.

2. Feedback and Comparison

The Electronic Valve Controller compares the feedback signal from the transmitter to the set-point. If the deviation exceeds the deadband, the valve control system is activated.

Display

The 131VC-1 has been engineered to be the industry’s most user friendly controller. With three digital displays areas (two offering up to 9 characters of true alphanumeric), the 131VC-1 effectively eliminates cryptic messages, sub-routines and loops that could confuse even the most experienced operator. The bright, crisp display is vacuum fluorescent, and offers much better readability than any other display technology. Additional operator-friendly features include: custom programmable alarm messages, illuminated keys, and an easy-to-use menu system.

Status Indicators - Four status indicators show the controller’s operating status at all times:

Manual Key Light: For manual control.

Set-point Key Light: For indication of remote control.

Output Indicator: “OUT” and indicator lights illuminate

when either output 1 or 2 are on.

Alarm Indicator: “ALM” and indicator lights illuminate when either output 1 or 2 are on.

Keys Pads: All menu entry, configuration, tuning and set-point controls is entered through rugged backlit rubber keys. A simple menu system prompts the operator, step by step, through all procedures. Security system prevents unauthorized changes to all values.

3. Valve Actuation

The Electronic Valve Controller actuates the solenoid controls, causing the valve to modulate as needed to regain the set-point condition.

Full Programmable Control of Valve Sensitivity and Valve Response

Designed with duplex output circuits (one to control the valve opening solenoid and one to control the valve closing solenoid ). The 131VC-1 Electronic Control System can be programmed to maintain precise control of any process. Each output circuit has an independently programmable proportional band and solenoid cycle time. By adjusting these control algorithms in combination, the response time can be varied over a wide range.

Proportional Band

The proportional band can be programmed from 1 to 999 percent of transmitter scale. Programming a narrow deviation band will result in faster valve response, whereas a wider band will result in slower response.

Proportional Response Time

The response time of the valve is proportional to how far the process variable is from the set-point. If there is only a small deviation, the solenoid “on-time” will be short and the valve will move slowly. For large deviations, the “on-time” will be longer and the valve speed will be faster.

Solenoid Cycle Time

The opening and closing solenoid pilots operate in “on-off” cycles. The cycle time is programmable to allow the valve to make a smooth transition to the set-point and avoid overshooting.

Dual Output Circuits

The two output circuits can be programmed independently to respond at different rates. For example: fast response above the set-point; slow response below the set-point.

Set-Point Rate of Change

The controller has a ramping function that will further control valve speed of operation. This feature is especially useful in applications where valve speed is critical and pipeline surges are possible. When turned on, the set-point rate of change feature is operational under the following conditions:

On power up, the set-point will ramp from the process variable value to the set-point value at a specified rate.

On a transfer from manual to automatic control, the setpoint will ramp from the process variable to the set-point value at a specified rate.

On any set-point change, the set-point will ramp from the current set-point to the new target set-point.

Pressure Control

Downstream pressure control is easily accomplished. The pressure transmitter range should be selected to provide the desired accuracy of pressure control. The set-point of the controller can be changed by the remote command signal or by manual adjustment at the controller panel. For pressure sustaining control, the transmitter is located upstream of the valve and the solenoid outs are reversed.

Flow Control

Flow control uses a flow transmitter in the configuration shown. The flow transmitter range should be selected to provide the desired accuracy of flow control. If desired, the transmitter may be located downstream of the valve, however, it should be a minimum of five to nine diameters downstream of the valve.

Position Control

For applications requiring control of valve position, use the optional Cla-Val X117 Valve Position Transmitter. This provides the feedback signal to the controller. A computer or programmable controller (PLC) may receive inputs from other sensors and output a position command signal for use in complex control applications.

Modulating Level Control

For modulating level control, the controller accepts the signal from the tank level transmitter as the remote set-point. This signal is then compared with the signal generated by an optional X117 Valve Position Transmitter to adjust the valve proportionally to the range of the level transmitter.

A second hydraulic pilot system is arranged in parallel with the electronic system. On power failure, a third solenoid switches the control from electronic to the backup hydraulic system. The hydraulic system will then modulate the valve to maintain preset system conditions. Virtually any hydraulic system can be used.

Direct Voltage Electronic Control

Customer supplied battery power, with a continuous charging system, operates the valve solenoids and controller in the event of power failure.

Open or Close Valve

Adds a third solenoid control to the pilot system which either opens or closes the main valve on power failure.

Transmitter Signal Failure

The 131VC-1 Electronic Control System contains several indispensible sub-routines that protect the system if there is a transmitter signal failure. The controller has, as standard, terminals for a second transmitter and can be configured to automatically default to that transmitter. The controller can also be configured to cause the valve to remain in last control position, to open or close at an electronically controlled rate, or alarm to an auxiliary hydraulic pilot system.

Remote Communications Failure

The 131VC-1 Electronic Control System is the final link in the communications system at the valve site. In the event of a failure, the controller will continues to function, maintaining the valve at the last set-point command or a pre-programmed setpoint. It can also have a new set-point entered on the key pad by the Operator.

POWER SUPPLY

Page 39

The Electronic Control System shall provide the interface between a remote computer system and the control valve. The controlled parameter signal shall be accepted through a 4-20 mA feedback signal. Local manual set-point control and full manual control of control valve solenoids is to be provided on the controller panel for local control.

Upon receiving the set-point command signal from the remote computer system, the controller will signal the valve to move and maintain the valve at the desired set-point. A vacuum fluorescent display of current status and set-point value in scalable engineering units shall be supplied.

The controller shall compare set-point and feedback values and adjust the valve accordingly to achieve the set-point. When the feedback signal deviates from the set-point value, the appropriate opening or closing solenoid on the control valve shall activate. As the feedback signal approaches the set-point, the solenoid output will pulse on and off to gradually return the measurement to set-point. One solid-state relay energizes for measurements condition below the set-point, while the other energizes for measurement, greater than set-point. These outputs shall be wired directly to or through intermediate relays to the opening and closing solenoids on the control valve. Solenoid output indicator lights shall illuminate when either the open or closed solenoid is activated.

The total cycle time between each pulse shall be programmable between 1 and 120 seconds. The duration of each pulse shall be directly proportional to the deviation from set-point outside of an adjustable deadband. The time proportioned outputs shall be independently adjustable for conditions above and below the set-point to properly tune valve response. The time proportional output band width shall be independently programmable between 1 and 999 percent of full scale. When the feedback signal returns within the deadband zone, the valve will maintain position. Provision shall be made to open/close/maintain position in the event of a loss of the feedback signal.

The operator interface shall consist of two rows of alphanumeric characters to display numeric values and units. Color coded alarm, status and mode indicators shall inform the operator of operating conditions. Security key codes shall protect against undesired changes to the controller. All programming shall be menu driven.

The controller shall be all solid-state construction with the internal chassis capable of being removed for inspection and adjustment. All program memory, including set-points and tuning parameters, shall be protected by an internal lithium battery rated for 10 year life.

Remote communications shall be accepted through a 4-20 mA DC analog set-point signal.When remote operation is selected, the controller shall monitor the remote set-point signal. When local control is selected, the set-point shall be changed at the controller keypad.

When optional remote digital communications are provided, the controller shall be capable of direct linkage to a computer or other instrumentation which has RS-232 or RS-485 communications. The Electronic Control System shall be the Cla-Val Model 131VC-1 as manufactured by Cla-Val, Newport Beach, CA.

Purchase Specifications

The electrical power used to energize the solenoid pilot system on the valve is routed through the 131VC-1 Electronic Control System. Because of practical limitations on wire size and distance, we recommend locating the controller near the valve itself.

Transmitter signals of 4-20 mA can travel great distances without difficulty, therefore, the controller does not need to be near the signal transmitter. For outdoor and high humidity indoor applications, we recommend installation in water-tight NEMA 4 enclosures.

Installation

Retrofitting CLA-VAL Control Valves

Existing hydraulically operated Cla-Val control valves can easily be converted to operate with the 131VC-1 Electronic Control System. The valve is modified by simply adding the Series 131 Solenoid Pilot System. The Series 131 Pilot System can be installed in parallel with the existing hydraulic pilot control for backup control in case of electrical power failure. In this case, the hydraulic pilot system must be isolated from the valve by a third solenoid valve (see Power Failure Options above).

When the existing Cla-Val control valve performs a combination of control functions (such as pressure reducing and pressure sustaining), the 131VC-1 Electronic Control System will control the primary function of the valve. The other secondary functions will continue to be controlled by the hydraulic pilot controls. Consult Factory for details.
