The Model 100-34 Hytrol Valve is used as the basic unit in almost all
Cla-Val automatic control valves for petroleum applications. The 100-34
is a hydraulically-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
100-34 Hytrol Valve is used in many types of piping system requiring
control, flow regulation, rate of flow control, or check valve operation.
