Pump Suction Control Valve
• Adjustable Opening Speed For Pump Suction Protection
• Pilot Control Provides Wide Flow Range With Minimal Pressure Variations
• Controlled Closing For System Protection
• Modulates Within 5% of Setting for Accurate Pressure Control
• Pressure Setting Adjustable
• Pressure Setting Not Affected by Pressure at Valve Discharge
The Model 50B-5KG Pump Suction Control Valve is designed specifically for Fire Pump Suction Control Service. It modulates to maintain the pump discharge in relation to the suction head available, thus assuring that the suction head pressure does not fall below the pre-set minimum.
Typical Installation
When there is a demand in the Fire System, the pump is started, delivering water from the supply source to the area of demand. To assure that the fire pump draw does not exceed the available water supply, the Model 50B-5KG, sensing the pump suction, modulates to prevent suction pressure from dropping below a pre-set minimum.
By maintaining minimum pressure requirements in the supply main, the main is protected from possible damage or backflow conditions. Also, a minimum supply pressure is provided for local fire apparatus.

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 effi ciency 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,
MODEL
100-01
Hytrol Valve
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.
Principles of Operation
Three Way
Pilot Control
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.
Three Way
Pilot Control
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
Restriction
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.

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).
SYMPTOM PROBABLE CAUSE REMEDY
Fails to Close
Fails to Open
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.
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.
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.)
Diaphragm assembly inoperative. Corrosion or excessive buildup on valve stem. (See Freedom of Movement Check)
Diaphragm damaged. (For valves in "reverse flow" only)
Clean and polish stem. Inspect and replace any damaged or badly eroded part.
Replace diaphragm.
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.
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.
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
Second: Valve is free to move and can’t close because of a worn out diaphragm.
valve cannot be serviced under pressure. Steps should be taken to remedy this situation before proceeding any further.
Third: Valve leaks even though it is free to move and the diaphragm isn’t leaking.

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.

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 independ­ent 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.

16" 1/2—20 24" 3/4-16 30” 3/4-16 36” 3/4-16
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.
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.
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
www.mmcontrol.com/claval-index.php
800-876-0036 847-356-0566
Inspection of Parts
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.
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.
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.)
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

INSTALLATION / OPERATION / MAINTENANCE
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 service 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. Cla­Val identifies main valve parts with the flange size of the stan­dard 100 Series main valve. Refer to the "Main Valve Sizes” chart below.

600 Series Hytrol Valve
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.
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.
MODEL
100-20
(Reduced Internal Port)
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.

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.’

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

800-876-0036 847-356-0566
For ordering repair kits, replacement parts, or for inquiries concerning valve operation, it is important to properly identify Cla-Val products already in service by including all nameplate data with your inquiry. Pertinent product data includes valve function, size, material, pressure rating, end details, type of pilot controls used and control adjustment ranges.
Identification Plates
For product identification, cast-in body markings are supplemented by identification plates as illustrated on this page. The plates, depending on type and size of product, are mounted in the most practical position. It
is extremely important that these identification plates are not painted over, removed, or in any other way rendered illegible.
