4", Cast Iron Wafer Swing Check Valve, BUNA-N Seat, 316SS Disc


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 316SS disc assures instantaneous closure to reversing flow, preventing build-up of momentum, the cause of damaging water hammer. The hinge pin design assures free movement of the disc and eliminates seizure under extreme conditions. Soft seat inserts are standard for positive sealing of hard-to-hold solvents and fluids. Lifting eye hook on 8” to 12” valves.

Notes

Manufacturer reserves the right to modify dimensions, materials, or design. Contact factory for certification. Valves are designed to operate on vertical and horizontal flow, see note 1.

NOTE 1
The wafer check valve is designed for installation between two pipe flanges in horizontal or vertical pipelines
(in the latter case upward flow is preferred).
