Powercheck Valve

• Built-in Automatic Check Valve

• Globe or Angle Pattern

• Drip-Tight, Positive Seating

• Threaded or Flanged Ends

• Packless Construction

The Cla-Val Model 100-30 Powercheck Valve is a

hydraulically operated diaphragm valve with a built-in check

feature to prevent return flow. Available in globe or angle

pattern, it consists of four major components: body,

intermediate chamber, diaphragm assembly, and cover. The

diaphragm assembly is the only moving part.

The diaphragm assembly is guided top, center and bottom by

a precision machined stem and utilizes a non-wicking

diaphragm of nylon fabric bonded with synthetic rubber. A

synthetic rubber disc retained on three and one half sides

forms a drip-tight seal with the renewable seat when pressure

is applied above the diaphragm. When pressure above the

diaphragm is relieved, the valve opens wide. The rate of

closing or opening can be controlled by modulating flow into

or out of the diaphragm chambers.

When a pressure reversal occurs, the valve will immediately

close, preventing reverse flow thru the valve. The split stem

will allow the disc retainer assembly to check closed

regardless of the position of the diaphragm.

Principle of Operation

100-30

Full Open Operation

When operating pressure below the

diaphragm is greater than the

pressure in the cover chamber, the

valve is held open, allowing full

flow.

Check Action

When a static condition or pressure

reversal occurs, the split stem

design allows the valve to instantly

check closed. Return flow is

prevented regardless

of the diaphragm's

position.

Tight Closing Operation

When pressure below the

diaphragm is relieved and operating

pressure is applied to the cover

chamber, the valve closes

drip-tight.

Four-Way Control

Note: For optimum operation of built-in check feature, installation with stem vertically up is recommended.
