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)
Note: Valve can be installed in the vertical or horizontal position.
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
.

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 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”
chart below.

numbers shown above to insure that cover seats evenly on the diaphragm
material and body.
2. Torque the bolt/nuts in three stages with a "Star" or "Cross-Over" pattern
for each stage:
A. To approximately 10% of final torque.
B. To approximately 75% of final torque.
C. To final required torque.
3. Valves that are to be tested to 375 PSI or higher should be retorqued
after 24 hours.
100-01 Hytrol Main Valve Assembly
Page 13
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.

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 CDHS-32 Electronic Actuated Differential Pressure Pilot
Control provides remote set-point adjustment and accurate differential pressure control for rate of flow control on Cla-Val 340 Series Control Valves.
Remote set-point command signals can be from any SCADA-type control
system that uses analog 4-20 mA signals. A precision orifice plate installed
with the valve creates differential pressure used for rate of flow control by
the CDHS-32. Operating on 12 to 24 VDC and consuming very little power,
it is an ideal control system for remote valve sites that may even be solar
powered. Existing manually-set Cla-Val 40 Series Rate-of-Flow control
valves can be retrofitted with CDHS-32 to add remote set-point control.
Verification of differential pressure and corresponding flow rate may be sent
to SCADA system from customer supplied differential pressure sensor
attached to orifice plate.
The CDHS-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
maximum pressure differential at orifice plate and corresponding flow rate
within preset limits. Pressure differential settings are linear between these
settings. Special USB connector cable and free downloadable software is
required to change built-in electronic range limits for differential pressure
and corresponding flow rate. Continuous internal monitoring of actuator
position results in smooth transitions between pilot set-points with no backlash or dithering. When power or control input fail, the CDHS-32 pilot
remains in automatic hydraulic control assuring system stability under all
conditions.

The CDHS-32 Is installed on Cla-Val 340 Series valves that maintain
flow rate and require this flow to be changed from a remote location. It
is also an effective solution for lowering costs associated with "confined
space" requirements by eliminating the need for entry in valve structure
for set-point adjustment. Additional pilot controls, hydraulic and/or electronic, are also available to perform multiple functions to fit exact system

DESCRIPTION
The Cla-Val CDHS-18 Differential Control Valve is a normally open,
spring loaded, diaphragm type valve that operates hydraulically and is
designed to close on a rising differential pressure. When used as a pilot
control with Cla-Val Valves, it acts as a flow limiting control.
INSTALLATION
The Differential Control may be installed in any position. There is one
inlet port and two outlet ports in the body for either straight or angle
installation. The outlet port senses the high pressure or inlet to the differential
producing device. One of the outlet ports can be used for a gauge
connection. The port above the diaphragm (located in the control cover)
is used to sense the low pressure or outlet side of the differential producing
device. A flow arrow is marked on the body casting.
OPERATION
The Differential Control is normally held open by the compression spring
and the sensing pressure above the diaphragm. When the rate of flow
through the main valve increases, the sensing pressure above the
diaphragm of the control decreases and the higher pressure at the outlet
port closes the control; which, in turn, closes the main valve. When the
rate of flow through the main valve decreases, the sensing pressure
above the diaphragm increases. This opens the control and in turn
opens the main valve. This action causes the main valve to modulate,
limiting the flow rate to the setting of the control.
ADJUSTMENT
The Differential Control Valve can be adjusted to limit the rate of flow as
specified on the data plate. Rate of flow adjustment is made by turning
the adjustment screw to vary the spring pressure on the diaphragm. The
greater the compression on the spring the higher the flow rate.
1. Turn the adjustment screw in (clockwise) to increase flow rate.
2. Turn the adjustment screw out (counterclockwise) to decrease flow
rate.
DISASSEMBLY
The Differential Control Valve should be removed from the Hytrol Valve
assembly. Make sure that pressure shutdown is accomplished prior to
disconnecting assembly. During disassembly inspect all threads for damage or evidence of cross-threading.
NOTE: A bench vice equipped with soft brass jaws should be used to
hold the valve body during disassembly and reassembly. DO NOT tighten
vice jaws more than enough to hold unit firmly. Excessive pressure may
spring or crack casting
1. Remove adjusting screw cap (16).
2. Loosen lock nut on adjusting stem assembly (9) and turn
adjusting screw counterclockwise to relieve tension on spring.
3. Remove bottom plug (8) and gasket (6).
4. Remove disc retainer assembly (5) and inspect sealing surface for
damage or wear. Replace if necessary.
5 Remove 8 screws (12) and carefully Iift off cover (2) spring guide
(10) and spring (13) can now be removed.
6. Remove diaphragm assembly.
7. Remove diaphragm nut (7) and diaphragm washer (4).
8. Remove diaphragm (3), inspect for damage and replace if neces-
sary.
9. Inspect all parts for damage, corrosion, wear, foreign particles, and
cleanliness.
10. Repair minor nicks and scratches, these may be polished out
using a fine grade of emery or crocus cloth.
REASSEMBLY
Prior to reassembly replace all parts which are damaged or worn. When
ordering replacement parts be sure to specify item, part number, and all
nameplate data.
1. Place diaphragm (3) on top of yoke (11) place diaphragm
washer (4) over diaphragm with rounded edges down or next

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.

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
CV
MODEL
N-CV (R-06/2018)
DESCRIPTION
The CV Control is an adjustable restriction which acts as a
needle valve when flow is in the direction of the stem. When
flow is in the reverse direction, the port area opens fully to
allow unrestricted flow. When installed in the control system of
a Cla-Val automatic valve, it can be arranged to function as
either an opening or closing speed control.
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
o
rder 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.
