4", Raised Face Wafer Silent Check Valve, All 316SS Construction
Consult factory for optional construction materials and installation instructions. Resilient seating of BUNA-N or VITON available for 4” size and larger.

We recommend that the valves be installed 7 to 10 pipe lengths away from the turbulence.

Sure Flow Wafer Check Valves are designed to close before the pump stops completely. This prevents flow reversal which eliminates water hammer and system surges associated with valve closure.

Notes

Manufacturer reserves the right to modify dimensions, materials, or design. Contact factory for certification.
The Flow Coefficient (Cv) is the number of gallons per minute of water flowing through a given size restriction at a pressure drop of one psi. To obtain the Cv factor for a given size check valve refer to table above.
