The Cla-Val Model 100S/2100S Seawater Service Hytrol Valve
is a hydraulically operated, diaphragm actuated, globe or
angle pattern valve. It consists of three major components:
body, diaphragm assembly and cover. The diaphragm assem­bly is the only moving part.

The body (ductile iron or cast steel) is epoxy coated and contains
a removable seat insert. The diaphragm assembly is guided top
and bottom by a precision machined stem. It utilizes a non-wick­ing diaphragm of nylon fabric bonded with synthetic rubber. A
resilient synthetic rubber disc retained on three and one half sides
by a disc retainer forms a drip-tight seal with the renewable seat
when pressure is applied above the diaphragm.

The Model 100S/2100S Seawater Service Hytrol Valve is the
basic valve used for seawater applications. It is the valve of
choice for system applications requiring deluge, pressure regu­lation, pressure relief, solenoid operation, rate of flow control, liq­uid level control or check valve operation. The rugged simplicity
of design and packless construction assure a long life of
dependable, trouble-free operation. It is available in various
materials and in a full range of sizes, with either screwed or
flanged ends. Its applications are unlimited.

Modulating Action

The valve holds any intermediate position
when operating pressures are equal above
and below the diaphragm. A Cla-Val “modu­lating” pilot control will allow the
valve to automatically compen­sate for line pressure changes.

Principle of Operation

Full Open Operation

When pressure in the

cover chamber
is relieved to a zone of lower pres­sure, the line pressure at the valve
inlet opens the valve, allowing full flow.

Tight Closing Operation

When pressure from the valve inlet
is applied to the cover chamber, the
valve closes drip-tight.

Purchase Specifications

The Model 100S/2100S shall be a hydraulically operated, diaphragm-actuated, globe or
angle pattern valve. It shall contain a resilient, synthetic rubber disc, having a rectangular
cross-section, contained on three and one-half sides by a disc retainer and disc guide,
forming a tight seal against a single removable seat insert. The diaphragm assembly, con­taining a valve stem, shall be fully guided at both ends by a bearing in the valve cover and
an integral bearing in the valve seat. This diaphragm assembly shall be the only moving
part and shall form a sealed chamber in the upper portion of the valve, separating operat­ing pressure from line pressure. The diaphragm shall consist of nylon fabric bonded with
synthetic rubber and shall not be used as a seating surface. Packing glands or stuffing
boxes are not permitted and there shall be no pistons operating the valve or its pilot con­trols. All necessary repairs shall be possible without removing the valve from the line. All
materials shall be compatible with seawater.
Valve shall be Model 100S/2100S manufactured by Cla-Val, Newport Beach, CA 92659-0325

Cla-Val Control Valves operate with maximum efficiency when mounted in horizontal piping with the main valve cover UP, however, other positions are acceptable. Due to
component size and weight of 8 inch and larger valves, installation with cover UP is advisable. We recommend isolation valves be installed on inlet and outlet for maintenance.
Adequate space above and around the valve for service personnel should be considered essential. A regular maintenance program should be established based on the specific
application data. However, we recommend a thorough inspection be done at least once a year. Consult factory for specific recommendations.

MODEL

• Reduced Cavitation Design

• Drip-Tight, Positive Seating Action

• Service Without Removal From Line

• Globe or Angle Pattern

• Every Valve Factory Tested

The Cla-Val Model 100-20 Hytrol Valve is a hydraulically operated,
diaphragm actuated, globe or angle pattern valve. It consists of
three major components: body, diaphragm assembly and cover.
The diaphragm assembly is the only moving part.

The diaphragm assembly is guided top and bottom by a precision
machined stem which utilizes a non-wicking diaphragm of nylon
fabric bonded with synthetic rubber. A resilient synthetic rubber
disc, retained on three and one-half sides by a disc retainer, forms
a drip-tight seal with the renewable seat when pressure is applied
above the diaphragm.

The reduced cavitation characteristics of the 100-20 Hytrol Valve is
the basis for the Cla-Val 600 Series. The rugged simplicity of
design and packless construction assure a long life of dependable,
trouble-free operation. It's smooth flow passages and fully guided
disc and diaphragm assembly assure optimum control when used
in piping systems requiring remote control, pressure regulation,
solenoid operation, rate of flow control or check valve operation.

Available in various materials and in a wide range of sizes. It's
applications are unlimited.

100-20

600 Series

Hytrol Valve

Principle of Operation

Full Open Operation

When pressure in the

cover chamber
is relieved to a zone of lower
pressure, the line pressure at the
valve inlet opens the valve, allowing
full flow.

Modulating Action

The valve holds any intermediate
position when operating pressure is
equal above and below the
diaphragm. Using a Cla-Val
“Modulating” Control will allow the
valve to automatically compensate

The Delrin

®

sleeved stem is designed for
applications where water supplies contain
dissolved minerals which can form
deposits that build up on the valve stem
and hamper valve operation. Scale build­up will not adhere to the Delrin

®

sleeve

stem. Delrin

®

sleeved stems are not
recommended for valves in continuous
operation where differential pressures are
in excess of 80 psi (2" and larger Hytrol valves).

Heavy Spring

-

suffix KH

The heavy spring option is used in
applications where there is low differential
pressure across the valve, and the
additional spring force is needed to help
the valve close. This option is best suited
for valves used in on-off (non-modulating)
service.

Anti-Cavitation Trim

-

suffix KO

Anti-Cavitation Trim components consist
of a stainless steel radial slotted disc guide
and seat. This system is used when high
differentials are present across the valve.

Water Treatment Clearance

-

suffix KW

This additional clearance is beneficial in
applications where water treatment
compounds can interfere with the closing
of the valve. The smaller outside diameter
disc guide provides more clearance
between the disc guide and the valve seat.
This option is best suited for valves used
in on-off (non-modulating) service.

Service and Installation

Cla-Val Control Valves operate with maximum efficiency when mounted in horizontal piping with the main valve cover UP, however, other
positions are acceptable. Due to component size and weight of 10 inch and larger valves, installation with cover UP is advisable. We recommend
isolation valves be installed on inlet and outlet for maintenance. Adequate space above and around the valve for service personnel should be
considered essential. A regular maintenance program should be established based on the specific application data. However, we recommend a
thorough inspection be done at least once a year. Consult factory for specific recommendations.

DESCRIPTION

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

INSTALLATION

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

OPERATION

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

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

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

ADJUSTMENT PROCEDURE

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

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

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

DISASSEMBLY

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

Refer to Parts List Drawing for Item Numbers.

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

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

See NOTE under REASSEMBLY.

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

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

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

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

stem must not be scored or scratched.

7. The seat (22) need not be removed unless it is damaged. If removal
is necessary use proper size socket wrench and turn counterclockwise.
Note: Some models have an integral seat in the body (7).

INSPECTION

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

REPAIR AND REPLACEMENT

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

REASSEMBLY

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

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

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

Do Not Cut O-Ring.

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

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

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

DESCRIPTION

The CRA Pressure Reducing Control automatically reduces a higher inlet
pressure to a lower outlet pressure. It is a direct acting, spring loaded,
diaphragm type valve that operates hydraulically or pneumatically and is
designed to sense pressure from a remote point. It may be used as a self­contained valve or as a pilot control for a Cla-Val Co. main valve. It will
hold a constant downstream pressure at the remote sensing point within
very close pressure limits.

OPERATION

The CRA Pressure Reducing Control is normally held open by the force
of the compression spring above the diaphragm; delivery pressure acts on
the underside of the diaphragm. Flow through the valve responds to
changes in pressure at the the sensing point.

INSTALLATION

The CRA Pressure Reducing Control may be installed in any position.
There is one inlet port and two outlets, for either straight or angle instal­lation. The second outlet port can be used for a gauge connection. A flow
arrow is marked on the body casting.

ADJUSTMENT PROCEDURE

The CRA Pressure Reducing Control can be adjusted to provide a deliv­ery pressure range as specified on the nameplate.

Pressure 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 pressure setting.

1. Turn the adjustment screw in (clockwise) to increase delivery
pressure.

2. Turn the adjustment screw out (counter-clockwise) to decrease
the delivery pressure. When pressure adjustment is completed,
tighten jam nut on adjustment screw and replace protective cap.

Flow rates are not critical during pressure setting. The approximate min­imum flow rates given in the table are for the main valve on which the CRA
is installed.

MAINTENANCE
Disassembly

To disassemble follow the sequence of the item numbers assigned to
parts in the sectional illustration.

Reassembly

Reassembly is the reverse of disassembly. Caution must be taken to
avoid having the yoke (17) drag on the inlet nozzle of the body (18).
Follow this procedure:

1. Place yoke (17) in body and screw the disc retainer assembly
(16) until it bottoms.

2. Install gasket (14) and spring (19) for 2-30 psi range onto plug
(13) and screw into body. Disc retainer must enter guide hole in
plug as it is assembled. Screw the plug in by hand. Use wrench
to tighten only.

3. Place gasket (25) and powertrol body (21) on yoke extension
(17). Refer to sectional view for proper reassembly of (21) onto
body (18).

4. Place lower diaphragm washer (24), "o" ring (22), diaphragm
(12), upper diaphragm washer (11), and belleville washer (20) on
yoke extension (17). Screw on diaphragm nut (10) finger tight.

5. Place two machine screws (4) through (21) (25) and screw into
body (18). Do not include the diaphragm (12) in this operation.
This holds parts aligned for next step, and allows the diaphragm
to move and be properly located during tightening of nut (10).

6. Hold the diaphragm so that screw holes in the diaphragm (12)

and powertrol body (21) align. Tighten diaphragm nut (10) with a wrench.
At the final tightening release the diaphragm and permit it to rotate
approximately 5° to 10°. The diaphragm holes should now be properly
aligned with the body holes.

To check for proper alignment proceed as follows:

Rotate diaphragm clockwise and counterclockwise as far as possible.
Diaphragm screw holes should rotate equal distance on either side of
powertrol body screw holes ±1/8".

Repeat assembly procedure until diaphragm and yoke are properly
aligned. There must be no contact between yoke and body nozzle during
its normal opening and closing movement. To simulate this movement
hold powertrol body and diaphragm holes aligned. Move yoke to open
and closed positions. There must be no evidence of contact or dragging.

7. Remove machine screws per step 5.

8. Install spring (9) with spring guide (8) on top of spring.

9. Install cover (5) using eight machine screws (4).

10. Replace adjusting screw (2) and nut (3), then cap (1).

INSTALLATION / OPERATION / MAINTENANCE

Flow Control

CV

MODEL

N-CV (R-5/05)

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.

Cla-Val Product

Identification

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.
