Silent Check Valve

 

Prevent water hammer in well pump applications
Vertical and horizontal mounting

Silent check valves were developed to eliminate water hammer due to water flow reversal in clear water pump applications. Valve opens when upstream pressure exceeds downstream pressure by 1/4 to 1/2 psi. An internal spring closes valve just prior to an equalizing pressure on both sides providing a quiet and shock less valve closing.

Both wafer and globe style valves are designed for use with Class 125/150 flanges. The globe style provides a 10% greater flow area due to its wide body confi guration. Valve body is cast iron with bronze plug, seat and bushings, stainless steel spring and screws and Buna-N O-ring.

The wafer style is rated 400 psi for 2" thru 6" and 200 psi for 8" thru 12". Globe style flanged valves 2" thru 12" are rated at 200 psi with Class 125 flanges and 400 psi with optional Class 250 flanges. Maximum recommended flow velocity for all valves is 12 feet/second.
