Cla-Val 100-29S - Manual

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.

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.
