Sure Flow Wafer Style Swing Disc Check Valves incorporate several features distinguishing them 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.
Note: It is recommended that valves be installed 7 to 10 pipe lengths away from the turbulence.
