Seawater Service Hytrol Valve

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 100-29S 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 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 100-29S Seawater

Service 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.

100-29S

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.
