4", Flat Face Flanged Cast Iron Silent Check Valve with 316SS Disc
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 Globe Style 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.
