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”

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. All four basic main valves have a 600 Series version available with all of the same benefits and size relationships. The following chart shows the relationship of Cla-Val main valve catalog numbers.

Technical Bulletin

300 Series (Single-Mode) Electronic Actuated Pilot Controls

Introduction

CDB-32, CDHS-32, CRA-32, CRD-32, and CRL-32 are pilot controls for Cla-Val 300 Series Electronic Actuated Control Valves. These controls offer the same hydraulic control of the valve as existing manually-set controls, along with additional remote electronic setpoint adjustment capabilities. The new pilot controls consist of a modified pilot control sub-assembly, and the 130VC-2 Electronic Actuator with mounting components. Complete controls are valve mounted with an accessory X56 Mounting Assembly.

I. O. M. Information

A. The 130VC-2 wiring diagram is included with this technical bulletin. The 5-wire cable is permanently attached to

actuator and should be terminated in suitable junction box. Care should be used when attaching to wires to avoid damage. There are no user serviceable parts inside the actuator and tampering or opening it will void the warranty.

B. For Installation, Operation and Maintenance information only on the pilot sub-assembly use instructions in the appropriate N-sheet for the manually adjusted pilot control. Since the 130VC-2 Electronic Actuator changes the setpoint adjustment of the control, all other service and maintenance information remains the same for both. See table below.

C. Additional service notes:

1. Before disassembly of pilot subassembly from 130VC-2 actuator, adjust pilot control to full minimum range setting with laptop computer and 130VC-2 software to ensure full adjustment range when reassembled.

2. Note orientation of sub-assembly ports and bracket. Coupler and blue Aluminum bracket will remain attached to actuator. Loosen and remove jam nut and washer from sub-assembly cover as sub-assembly is removed from 130VC-2 bracket. Count number of turns counterclockwise of pilot adjustment shaft from minimum range set position to full out stop position. See pilot drawing.

3. After servicing the pilot sub-assembly, re-establish minimum spring setting by manually turning adjusting screw counterclockwise until it stops (full out stop position). Then, turn in same number of turns found in step 2 to minimum range set position.

4. Do not lubricate coupler slots. A small amount of waterproof anti-seize grease is used only on sub-assembly adjusting screw threads and contact point with spring guide inside cover.

5. Reinstall sub-assembly to bracket with jam nut and washer. Check coupler slots and adjusting screw pin are lined up while installing actuator to bracket. Be sure to retain original alignment of sub-assembly with bracket when tightening jam nut and washer. A slight manual adjustment of adjusting screw may help align the coupler to adjusting screw. See pilot assembly drawing.

6. After reinstalling onto valve, use laptop computer and 130VC-2 software to reset range values.

The Cla-Val Model CRL-32 Electronic Actuated Pressure Sustaining Pilot Control provides remote set-point adjustment and accurate pressure sustaining control on Cla-Val 350 Series Control Valves. Remote set-point command signals can be from any SCADA-type control system that uses analog 4-20 mA signals. The CRL-32 senses upstream pressure with a remote hydraulic connection. 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-32 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-32 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. Special USB connector cable and free downloadable software is required to change built-in electronic range limits for upstream sustained pressure. 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 CRL-32 pilot remains in automatic hydraulic control assuring system stability under all conditions.

Typical Applications

The CRL-32 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. Additional pilot controls, hydraulic and/or electronic, are also available to perform multiple functions to fit exact system requirements.

N-130VC-2 Wiring Diagram (R-3/2011)

FIELD WIRING STEPS:

The 5-wire cable is permanently attached to 130VC-2 Actuator and should be terminated in suitable junction box for all field wires. Care should be used when attaching to wires to avoid damage. Installation of suitable protection from lightning is recommended.

A.) Attach 12 to 24 VDC power to 130VC-2 Actuator permanent cable. Black wire (2) is common for - power;

Red wire (1) is for + power. No load current draw is 60 mA, Maximum load current draw is 800 mA, Polarity Protected.

B.) Attach 4 to 20 mA analog Remote Command Input to 130VC-2 Actuator permanent cable. Black wire (2) is

common for - return; Yellow wire (3) is for + sink. Non-isolated.

C.) Blue and Green wires are not used at this time.

IMPORTANT NOTICE:

Do not connect power supply to Command Input (Yellow wire) as this can damage the actuator and is not covered by warranty.

Factory default for 130VC-2 Actuator range is 32 Series pilot subassembly full spring range scaled to match the 4 to 20 mA Remote Command Input signal. Range Parameter Kit sets scale limits to values less than pilot spring range during valve start-up and when servicing pilot sub-assembly. Kit includes: 1) Special Cla-Val USB communications cable (p/n20519203A order separately) and 2) Special software as free download from Cla-Val web-site: www.cla-val.com.

INSTALLATION / OPERATION / MAINTENANCE

130VC-2 Electronic Actuator for 32 Series Pilot Controls

Thank you for purchasing a 32 Series Electronic Control with 130VC-2 “e-Drive” Actuator. With proper maintenance, the actuator will perform indefinitely and provide very accurate and reliable valve control. It is built with the latest technology utilizing the highest quality components.

32 Series Controls

The 32 Series Actuated Pilot Controls for 300 Series Valves consist of a hydraulic pilot subassembly and 130VC-2 Actuator. The Cla-Val Model CDHS-32, CRA-32, CRD-32, and CRL-32 pilot controls are factory set to full adjustment range of the pilot subassembly. The 130VC-2 Actuator accepts a 4 - 20 mA remote command set-point and positions spring-loaded hydraulic pilot subassembly as it maintains set-point of pressure or flow rate. The pilot subassembly is automatically linear between the limit settings.

32 Series Control Operation

A.) The 130VC-2 actuator allows 32 Series Controls to be used in valve remote control applications where a simple change of pilot set-point is needed. The pilot spring range is factory default scaled to a 4 - 20 mA command input signal. SCADA instrumentation provides set-point control and verification communication based on this scale.

B.) Other suitable valve remote control applications are where 4 - 20 mA command input signal is calibrated to specific high and low range values. SCADA instrumentation provides set-point control and verification communication based on system dynamic conditions and valve’s re-ranged scale. Using a laptop computer, the 130VC-2 actuator is calibrated in the field to specific minimum and maximum pressure or flow control settings that are in direct proportion to 4 - 20 mA command signal. Once values are established, the valve will be linear between limits and set-point will not exceed limits throughout the 4 - 20 mA signal range. For example, when actuator is calibrated to 4 mA = 50 psi to 20 mA = 100 psi, a 12 mA command signal will result in a 75 psi set point.

32 Series Actuator Hardware Set-up

BEFORE running actuator or software program, complete the following hookup steps:

A.) Use good field wiring practices for low voltage DC analog instrumentation wiring (use 18-gauge twisted pair shielded wire minimum). Avoid potential ground loops. Avoid over tightening wiring connector fasteners.

B.) The enclosure is rated IP-68 (similar to NEMA 6P) submersible for short periods of time. It is not intended for continuous underwater use. Consult Cla-Val factory technical support if you have questions.

C.) The five-wire cable is permanently attached to 130VC-2 actuator and should be terminated in suitable junction box for all field wires. Care should be used when attaching to wires to avoid damage. Installation of suitable protection from lightning is recommended.

D.) There are no user serviceable parts inside the actuator

and tampering or opening it will void the warranty.

CAUTION! The five-wire actuator cable is permanently attached. Internal damage not covered by warranty will occur if cable is shortened or removed.

FIELD WIRING STEPS:

Download Wiring Diagram from website (www.cla-val.com)

A.) Attach 12 to 24 VDC power to 130VC-2 Actuator cable. Black wire is common for - power; Red wire is for + power. Provide minimum 800 mA supply.

B.) Attach 4 to 20 mA analog Remote Command Input (from SCADA system or loop calibrator) to 130VC-2 Actuator cable. Black wire is common for - return; Yellow wire is for + sink.

C.) Blue and Green wires are not used at this time.

CAUTION! Do NOT Mix connections to Red, Yellow, or Black wires. Serious damage to 130VC-2 Actuator will occur if 24 VDC + positive power is connected to Black or Yellow wires and not to Red wire. Damage is NOT covered by warranty.

D.) After wiring is complete and actuator is powered, it can be used with 4 - 20 mA remote command input signal scaled to factory default pilot control adjustment range (Operation A, above).

Troubleshooting Actuator Set-up

1.) The actuator LED will remain red for approximately 30 seconds after power on, and then will switch to green indicating actuator is OK and that internal start-up test is complete.

2.) The actuator LED blinks red if there is a problem. After resolving the problem, reset the actuator by turning power off for ten seconds then on again.

3.) If other problems occur, please contact Cla-Val factory technical support.

32 Series Software Kit

For Operation A (above) applications, no changes to the 32 Series control preset values are needed. For Operation B (above) applications, the 32 Series Software kit is used to ONLY change factory-set values of: 1) range limits (high and low), 2) rotational speed of actuator, and 3) loss of signal mode. It is used only for set-up of 32 Series pilot controls during initial valve start-up or during valve repair.

The Cla-Val 130VC-2 Software Kit is required to communicate between your Windows XP laptop computer and 130VC-2 Actuator. It consists of a free software program, a special USB connector cable, and these instructions. The software is obtained by downloading from our website. Only one cable is needed to work with all 130VC-2 Actuators. Replacement cables (p/n 20519203A) can be ordered at extra cost.

Do not use this software for remote control of 130VC-2 Actuator.

You will have to browse to the Cla-Val folder created during download where the driver file is located. Use the following instructions to manually activating the cable driver.

Page 21

1) First, be sure hardware set-up and wiring to actuator is completed. Connect laptop computer to actuator using special USB cable. Be sure computer is on and actuator is powered. Check that Actuator LED is steady green.

2) Start the CLA-VAL actuator software by clicking on “e-Drive” desktop icon. After program opens, the Configuration mode tab will be displayed as default. System values are displayed for pressure or flow settings. Click on setting range values and enter new system pressure or flow values for 4 mA and 20 mA settings. Engineering Units can be changed to PSI to Bar or Kpa, GPM to L/S and inches to meters.

3) Click on Read parameters button to display Calibration tab window with system values and display of General Information. The date of last calibration, the average and total working time since first power up, the number of starts, the serial number, the Firmware version, and the maximum and minimum recorded temperature inside the actuator are displayed. Also, Calibration tab window will open without clicking on Read parameters button.

4) Open Configuration tab window to change Rotation Speed. Change speed by adjusting actuator on and off times to equal slower or faster net rotation speed. Factory default setting of one second on and five seconds off is a net rotation speed of about one rpm. Longer off times will slow down the actuator. Maximum ratio of 1/1 is a net speed of six rpm. Click on download to actuator button to make this parameter change without affecting other settings.

Slower rotation speeds are recommended.

5) Open Calibration tab mode to set (Loss-of-Signal mode). Select one of three options for actuator action upon loss of 4 - 20 mA command input signal. If actuator has power it will do one of the following:

Go to 4 mA: Actuator will decrease pilot setting to 4 mA position. Last position: Actuator will stay in last position. Highly recommended

Go to 20 mA: Actuator will increase pilot setting to 20 mA position.

Click on download to actuator button to make this parameter change.

In the event of loss of power, actuator will stay in last position and valve will control at last set-point.

Starting Actuator Software

32 Series Actuator and Software Set-up

Change 130VC-2 Actuator configuration from factory default settings, by using free download software from website (www.cla-val.com). To set up a communication link with 130VC-2 Actuator, first install software and cable driver and then special USB communications cable in laptop computer. After installing driver and communication cable, the actuator must be powered for link to work. Follow hardware set-up and wiring diagram instructions.

1) In Calibration Tab mode, click “Calibration Mode” button. This will allow temporary manual control of actuator for setting new pilot control limits. These values will then be sent to actuator at completion of calibration. Check that actuator LED is blinking red/green during calibration mode process. All High and Low point settings steps must be completed in order shown. Use the cancel button to input new values.

2) Look at pressure gauge or flow sensor, use Increase actuator or Decrease actuator buttons until desired LOW pressure or flow point (same value used in Configuration tab window and showing in Low Point window) is reached. Press Stop actuator button to stop actuator. Use good quality gauges and be as precise as possible. If calibrating CDHS-32 for flow rate using an orifice plate, a calibrated differential pressure gauge or transmitter is recommended.

3) Once desired low pressure or flow is reached and actuator is topped, click Low point setting button.

4) Look at pressure gauge or flow sensor, use Increase actuator or Decrease actuator buttons until desired HIGH pressure or flow point (same value used in Configuration tab window and showing in High Point window) is reached. Press Stop actuator button to stop actuator.

5) Once the high pressure or flow is reached and actuator is stopped, click High point setting button.

6) Finally, click Download calibration button to store values in actuator. High point, Low point, Loss-of-Signal, and Rotation speed settings are sent to actuator. Actuator LED will change to green when complete. Unplug cable from actuator and replace protective cap. 130VC-2 Actuator is now ready to accept 4 - 20 mA command signal from permanent cable Yellow and Black wires.

In some instances it may not be physically possible to reach desired system High pressure point due to possibility of putting too much pressure in a zone. Projection calibration mode is an ideal solution for this situation.

1) Look at pressure gauge or flow sensor, use Increase actuator or Decrease actuator until HIGH pressure point is reached. Press the Stop actuator button. Use good quality gauges and be as precise as possible. If calibrating CDHS-32 for flow rate using an orifice plate, a calibrated differential pressure gauge or transmitter is recommended. Once low pressure or flow is reached, click on Low point setting button.

2) Look at pressure gauge or flow sensor and use Increase actuator or Decrease actuator buttons to increase pressure or flow as close as is practical to desired HIGH pressure point.

3) Enter this value in projected High point calibration window.

4) Next, click on the High point setting button, and then click on the Download calibration button. The actuator automatically projects range to desired high point value entered in Configuration tab window.

5) New projected High point, Low point, Loss-of-Signal, and Rotation speed settings are sent to actuator. Actuator LED will change to green when complete. Unplug cable from actuator and replace protection cap, actuator is now ready to accept 4 - 20 mA command signal from permanent cable Yellow and Black wires.

In some applications it may not be physically possible to reach the low pressure point due to not being able to lower pressure in a zone. Projection calibration mode is an ideal solution for this situation.

1) Look at pressure gauge or flow sensor and use Increase actuator or Decrease actuator until LOW pressure point is reached. Press the Stop actuator button. Use good quality gauges and be as precise as possible. If calibrating CDHS-32 for flow rate using an orifice plate, a calibrated differential pressure gauge or transmitter is recommended. Once high pressure or flow is reached and actuator stopped, click on high point setting button.

2) Look at the pressure gauge or flow sensor and use Increase actuator or Decrease actuator buttons to decrease pressure or flow as close as practical to desired LOW pressure point.

3) Enter this value in the projected Low point calibration window.

4) Next click on Low point setting button, and then click on Download calibration button. The actuator automatically projects range to desired low point value entered in Configuration tab window.

5) New projected Low point, High point, Loss-of-Signal, and Rotation speed settings are sent to actuator. Actuator LED will change to green when complete. Unplug cable from actuator and replace protection cap, actuator is now ready to accept 4 - 20 mA command signal from permanent cable Yellow and Black wires.

If it is not practical to reach both high and low system value settings, then both projection procedures can be used. Allow at least one fourth of total range between high and low starting points. Accuracy of projected values is based on accuracy of initial value and any error will be magnified when projected from starting point.

Static calibration can create low and high pressure points for the 4 and 20 milliamp signals without rotating the actuator.

1) Determine high and low pressure that corresponds to the 4-20 mA signals.

2) Open the "Static Calibration" mode.

3) Use existing system pressure as a reference point or change using the increase.

4) Once desired reference setting is attained, consult spring chart to obtain pressure change per pilot revolution.

5) Calculate the number of turns between the reference pressure and the low and high values.

6) Enter these numbers into the "Turn to low and to high points". Numbers must be positive and can contain up to decimal points.

7) Click "Download Calibration" button to complete actuator setup.

8) Click cancel button to restart calibration.

Example: Required pressure range for 4-20 mA signals is 55 to 95 psi and system pressure is 70 psi. The 20-105 CRD-32 is

13 psi per turn. Therefore, 95 minus 55 divided by 13 = 1.92 turns is entered into the high point window. For the low point settings: 70 minus 55 = 1.15 turns which is entered into the low point window. (Remember to click "Download Calibration" button).

Spring Chart - PSI change per complete pilot revolution

CRD 15 -75 = 10.2 psi per turn CRD 2-105 = 13 psi per turn CRD 30-300 = 29 psi per turn

Troubleshooting FAQ

What are the default settings for the 130VC-2 actuator?

Factory default setting for 130VC-2 Actuator range parameter is the full pilot spring range scaled to match the 4 to 20 mA Remote Command Input analog signal. Factory default setting for 130VC-2 Actuator rotation speed is one rpm with 24 VDC power.

How do I get the software to work with the actuator?

To set up a link with 130VC-2 Actuator, first install cable driver and then the special USB communications cable. After installing driver and communication cable, the Actuator must be powered for link to work. Follow wiring diagram and hardware hookup instructions. Download Wiring Diagram from website (www.cla-val.com).

How do I install Special USB Communication Cable?

When 130VC-2 communications cable is installed in your laptop computer USB port for the first time, Windows will search your computer for the cable USB driver. If Windows Plug and Play does not automatically find the driver and connect to actuator, then the cable driver must be set up manually. Windows will take you step-by-step through the manual set up process. The cable USB driver is installed during software download. You will have to browse to the Cla-Val folder created during download where the driver file is located. Details are in this manual.

My computer does not have a USB port

Older laptop computers with only Serial port may have a problem using USB to Serial adapter with special USB connector cable and communicating with 130VC-2 actuator. Make sure the USB to Serial adapter cable is less than 18 inches long. Also, USB extension cables should not be used because they will degrade signals and cause problems. If problem persists, consult Cla-Val factory technical support.

Can I set both high and low setting points by projection?

Both projection procedures can be used if it is not practical to reach high and low settings. Allow at least one fourth of total range between high and low starting points. Accuracy of projected values is based on accuracy of initial value and any error will be magnified when projected from starting point.

Why is actuator LED still blinking red/green after I downloaded the settings?

Once the calibration mode button is activated, all steps must be done before downloading is begun. Actuator LED will show green when downloading is successful and complete.

Can I make a file ahead of time and download it to 130VC-2 later?

All hardware hookup steps must be completed before program will communicate and change 130VC-2 parameters. Until wiring and power connections are made to the actuator, this program can be opened, but new parameters can not be created or stored or sent to the actuator. Changes to parameters must be done "live" and while control valve is operating. Actuator LED will show green when downloading is successful and complete.

Can I make a file ahead of time and download it to 130VC-2 later?

DESCRIPTION

The CRL Pressure Relief Control is a direct acting, spring loaded, diaphragm type relief valve. It may be used as a self-contained valve or as a pilot control for a Cla-Val Main valve. It opens and closes within very close pressure limits.

INSTALLATION

The CRL Pressure Relief Control may be installed in any position. The control body (7) has one inlet and one outlet port with a side pipe plug (24) at each port. These plugs are used for control connections or gauge applications. The inlet in the power unit body (6) is the sensing line port. A flow arrow is marked on the body casting.

OPERATION

The CRL Pressure Relief Control is normally held closed by the force of the compression spring above the diaphragm; control pressure is applied under the diaphragm.

When the controlling pressure exceeds the spring setting, the disc is lifted off its seat, permitting flow through the control.

When controlling pressure drops below spring setting, the spring returns the control to its normally closed position.

ADJUSTMENT PROCEDURE

The CRL Pressure Relief Control can be adjusted to provide a relief setting at any point within the range found on the nameplate.

Pressure adjustment is made by turning the adjustment screw (9) to vary the spring pressure on the diaphragm. Turning the adjustment screw clockwise increases the pressure required to open the valve. Counterclockwise decreases the pressure required to open the valve.

When pressure adjustments are complete the jam nut (10) should be tightened and the protective cap (1) replaced. If there is a problem of tampering, lock wire holes have been provided in cap and cover. Wire the cap to cover and secure with lead seal.

DISASSEMBLY

The CRL Pressure Relief Control does not need to be removed from the line for disassembly. Make sure that pressure shut down is accompanied prior to disassembly. If the CRL is removed from the line for disassembly be sure to use a soft jawed vise to hold body during work.

Refer to Parts List Drawing for Item Numbers.

1. Remove cap (1), loosen jam nut (10) and turn adjusting screw counterclockwise until spring tension is relieved.

2. Remove the eight screws (4) holding the cover (3) and powerunit body (6). Hold the cover and powerunit together and place on a suitable work surface.

See NOTE under REASSEMBLY.

3. Remove the cover (3) from powerunit body (6). The spring (12) and two spring guides (11).

4. Remove nut (13) from stem (19) and slide off the belleville washer (14), the upper diaphragm washer (15) and the diaphragm (16).

5. Pull the stem (19) with the disc retainer assembly (21) through the bottom of powerunit. The lower diaphragm washer (17) will slide off of stem top.

6. Remove jam nut (23) and disc retainer assembly (21) from stem. Use soft jawed pliers or vise to hold stem. The polished surface of

stem must not be scored or scratched.

7. The seat (22) need not be removed unless it is damaged. If removal is necessary use proper size socket wrench and turn counterclock

wise. Note: Some models have an integral seat in the body (7).

INSPECTION

Inspect all parts for damage, or evidence of cross threading. Check diaphragm and disc retainer assembly for tears, abrasions or other damage. Check all metal parts for damage, corrosion or excessive wear.

REPAIR AND REPLACEMENT

Minor nicks and scratches may be polished out using 400 grit wet or dry sandpaper fine emery or crocus cloth. Replace all O-rings and any damaged parts. When ordering replacement parts, be sure to specify parts list item number and all nameplate data.

REASSEMBLY

In general, reassembly is the reverse of disassembly. However, the following steps should be observed:

1. Lubricate the O-Ring (18) with a small amount of a good grade of waterproof grease, (Dow Corning 44 medium grade or equal). Use grease sparingly and install O-ring in powerunit body (6).

2. Install stem (19) in powerunit body (6). Use a rotating motion with minimum pressure to let stem pass through O-ring.

Do Not Cut O-Ring.

3. Install O-ring (5) at top of stem (19). Place lower diaphragm washer (17) on the stem with the serrated side up. Position diaphragm (16), upper diaphragm washer (15), with serration down, and belleville washer (14) with concave side down.

4. Position powerunit body (6) as shown on parts list drawing (top view).

5. Continue reassembly as outlined in disassembly steps 1 through 3.

The strainer is designed for use in conjunction with a Cla-Val Main Valve, but can be installed in any piping system where there is a moving fluid stream to keep it clean. When it is used with the Cla-Val Valve, it is threaded into the upstream body port provided for it on the side of the valve. It projects through the side of the Main Valve into the flow stream. All liquid shunted to the pilot control system and to the cover chamber of the Main Valve passes through the X46 Flow Clean Strainer.

• Self Scrubbing Cleaning Action

• Straight Type or Angle Type

The Cla-Val Model X46 Strainer is designed to prevent passage of foreign particles larger than .015". It is especially effective against such contaminant as algae, mud, scale, wood pulp, moss, and root fibers. There is a model for every Cla-Val. valve.

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.

Flow Clean Strainer

X46

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:

• Catalog Number X46

• Straight Type or Angle Type

• Size Inserted Into and Size Connection

• Materials

DISASSEMBLY

Do not attempt to remove the screens from the strainer housing.

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.
