316SS Hytrol Valve

100-44

MODEL

• All 316 Stainless Steel

• Reduced Cavitation Design

• Drip-Tight, Positive Sealing Action

• Service Without Removal From Line

• Every Valve Factory Tested

• Three-Year Warranty

The Cla-Val Model 100-44 Hytrol 316SS Valve is a hydraulically operated,
diaphragm actuated, globe pattern valve with all 316 Stainless Steel metal
parts. Specially designed 316 Stainless Steel removable slip-on flanges
provide 150 or 300 ANSI class flange connections that meet ANSI and ISO
standards. This valve is ideal for control valve applications where fluid
compatibility is often a problem. The standard Electropolish finish on the
316 Stainless Steel parts offers extreme corrosion resistance to many
industrial fluids such as seawater, high alkyl or high acid concentrations
or other aggressive or corrosive fluids.

The Model 100-44 Hytrol consists of these major components: body,
flanges, diaphragm assembly and cover. The diaphragm assembly is the
only moving part and is guided top and bottom by a precision-machined
stem. A non-wicking diaphragm of nylon fabric reinforced, synthetic rubber
creates the control chamber for the valve. A resilient, synthetic rubber disc
forms a drip-tight seal, with the renewable seat, when pressure is applied
to the control chamber. The rugged simplicity of design and packless con­struction assures a long life of dependable, trouble-free operation. Smooth
flow passages and fully guided 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.

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 for line
pressure changes.

Tight Closing Operation

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

DESCRIPTION

The Cla-Val Model CRD Pressure Reducing Control automatically reduces
a higher inlet pressure to a lower outlet pressure. It is a direct acting,
spring loaded, diaphragm type control that operates hydraulically or pneu­matically. It may be used as a self-contained valve or as a pilot control for
a Cla-Val main valve. It will hold a constant downstream pressure within
very close pressure limits.

OPERATION

The CRD Pressure Reducing Control is normally held open by the force of
the compression spring above the diaphragm; and delivery pressure acts
on the underside of the diaphragm. Flow through the valve responds to
changes in downstream demand to maintain a pressure.

INSTALLATION

The CRD 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 gage connection. A flow
arrow is marked on the body casting.

ADJUSTMENT PROCEDURE

The CRD 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.

3. When pressure adjustment is completed tighten jam nut on
adjusting screw and replace protective cap.

4. When this control is used, as a pilot control on a
Cla-Val main valve, the adjustment should be made
under flowing conditions. The flow rate is not critical,
but generally should be somewhat lower than normal
in order to provide an inlet pressure several psi higher
than the desired setting

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 and 2-6.5 psi

range onto plug (13) and fasten 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 diaphragm (12) diaphragm washer (11) and belleville
washer (20) on yoke. Screw on hex nut (10).

4. Hold the diaphragm so that the screw holes in the
diaphragm and body align. Tighten diaphragm nut with
a wrench. At the final tightening release the diaphragm
and permit it to rotate 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
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 movement. To simulate this movement hold body
and diaphragm holes aligned. Move yoke to open and closed posi­tions. There must be no evidence of contact or dragging.

5. Install spring (9) with spring guide (8).

6. Install cover (5), adjusting screw (2) and nut (3), then cap (1).

The approximate minimum flow rates given in the table are for the main valve
on which the CRD is installed.

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.

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-3/2011)

DESCRIPTION

The Cla-Val Model CV Flow Control is a simply-designed,
spring-loaded check valve. Rate of flow is full flow in one direc­tion and restricted in other direction. Flow is adjustable in the
restricted direction. It is intended for use in conjunction with a
pilot control system on a Cla-Val Automatic Control Valve.

OPERATION

The CV Flow Control permits full flow from port A to B, and
restricted flow in the reverse direction. Flow from port A to B
lifts the disc from seat, permitting full flow. Flow in the reverse
direction seats the disc, causing fluid to pass through the clear­ance between the stem and the disc. This clearance can be
increased, thereby increasing the restricted flow, by screwing
the stem out, or counter-clockwise. Turning the stem in, or
clockwise reduces the clearance between the stem and the
disc, thereby reducing the restricted flow.’

INSTALLATION

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

DISASSEMBLY

Follow the sequence of the item numbers assigned to the
parts in the cross sectional illustration for recommended
order of disassembly.

Use a scriber, or similar sharp-pointed tool to remove O-ring
from the stem.

INSPECTION

Inspect all threads for damage or evidence of cross- thread­ing. Check mating surface of seat and valve disc for exces­sive scoring or embedded foreign particles. Check spring for
visible distortion, cracks and breaks. Inspect all parts for
damage, corrosion and cleanliness.

CLEANING

After disassembly and inspection, cleaning of the parts can
begin. Water service usually will produce mineral or lime
deposits on metal parts in contact with water. These
deposits can be cleaned by dipping the parts in a 5-percent
muriatic acid solution just long enough for deposits to dis­solve. This will remove most of the common types of
deposits. Caution: use extreme care when handling acid.
If the deposit is not removed by acid, then a fine grit (400)
wet or dry sandpaper can be used with water. Rinse parts
in water before handling. An appropriate solvent can clean
parts used in fueling service. Dry with compressed air or a
clean, lint-free cloth. Protect from damage and dust until
reassembled.

REPAIR AND REPLACEMENT

Minor nicks and scratches may be polished out using a fine
grade of emery or crocus cloth; replace parts if scratches
cannot be removed.

Replace O-ring packing and gasket each time CV Flow
Control is overhauled.

Replace all parts which are defective. Replace any parts
which create the slightest doubt that they will not afford com­pletely satisfactory operation. Use Inspection steps as a
guide.

REASSEMBLY

Reassembly is the reverse of disassembly; no special tools
are required.

TEST PROCEDURE

No testing of the flow Control is required prior to reassembly
to the pilot control system on Cla-Val Main Valve.
