The Cla-Val Model 40-32 Hytrol Valve is used as the basic unit in almost all
Cla-Val automatic control valves for petroleum application. The 40-32 is a
Hydaulically-operated, diaphragm actuated, globe or angle pattern valve. It is
available in various materials and full range of sizes. It consists of three major
components: body, diaphragm assembly and cover. The diaphragm assembly
is the only moving part. The rugged simplicity of design and packless
construction assure a long life dependable, trouble-free operation. Should the
diaphragm become damaged the valve will close tight, providing “fail safe”
operation. The 40-32 Hytrol Valve is used in many types of piping system
requiring control, flow regulation, rate of flow control, or check valve operation.
