The Cla-Val Model 100-22 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: the body, intermediate chamber, diaphragm

assembly and cover. The diaphragm assembly is the only moving

part.

The diaphragm assembly which is guided top, center and bottom by a

precision machined stem utilizes an FDA approved 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 the flow into or out of the cover chamber. When a pres-

sure reversal occurs the valve will immediately close, preventing

reverse flow through the valve. The split stem will allow the disc

retainer assembly to check closed regardless of the position of the

diaphragm.

The Model 100-22 Powercheck Valve is recommended on system

applications where a positive check feature is necessary to prevent

reverse 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.

• Built-in Automatic Check Valve

• Reduced Cavitation Design

• Service Without Removal From Line

• Packless Construction

• Drip-Tight and Positive Seating

Powercheck Valve

Full Open Operation

When operating pressure below the

diaphragm is greater than the pres-

sure in the cover chamber, the valve

is held open, allowing full flow.

Tight Closing Operation

When pressure below the

diaphragm is relieved and operating

pressure is applied to the cover

chamber, the valve closes

drip-tight.

Principle of Operation

Four-Way Control

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