Pressure Reducing, Surge & Deadman Shut-Off Valve

The Cla-Val Model 90AF-4A-3 Combination Pressure Reducing, Surge and Deadman Shutoff Valve 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 90AF-4A-3 Hytrol Valve is used in many types of piping system requiring control, flow regulation, rate of flow control or check valve operation.
