ASME Class 125 Wafer Swing Disc Design

The Wafer Swing Check Valve incorporates several features distinguishing it from conventional check valves for silent, fast, non-slam operation. The most prominent of these is the accurately machined disc and its special quick closing action. Spring loading of the 316 Stainless Steel disc assures instantaneous closure to reversing flow, preventing build-up of momentum, which is the cause of damaging water hammer. The hinge pin design assures free movement of the disc and eliminates seizure under extreme conditions.

A Buna-N soft seat insert on the CSW125IS is standard for positive sealing of hard-to-hold solvents and fluids. A lifting eye hook is standard on 8” to 16” valves.
