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.

Pump Suction Control Valve

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 efficiency
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.

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.

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.

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

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.

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

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

Hytrol Valve Service Data

MODEL

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.

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. All four basic main valves have a 600 Series version
available with all of the same benefits and size relationships.

INSTALLATION / OPERATION / MAINTENANCE

Flow Control

CV

MODEL

N-CV (R-1/08)

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 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.

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.

Proper Identification

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.
