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 con-
struction assures a long life of dependable, trouble-free operation. Smooth
flow passages and fully guided diaphragm assembly assure optimum con-
trol, when used in piping systems requiring remote control, pressure regula-
tion, solenoid operation, rate of flow control or check valve operation.
Principle of Operation
Full Open Operation
When pressure in the cover cham-
ber is relieved to a zone of lower
pressure, the line pressure at the
valve inlet opens the valve, allow-
ing 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 automati-
cally 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.
