Description

PVC-U/UPVC plastic swing check valve,1/2& quot; to 12”, flange ANSI CL150

swing check valve is a butterfly-style check valve in which the disc, the movable part to block the flow, swings on a hinge or trunnion, either onto the seat to block reverse flow or off the seat to allow forward flow. the?valve shut off depends on gravity (weight of disc) and reverse flow. The pivot point of the swing check is outside the periphery of the disc and, the greater the head, the greater the possibility that the fluid will flow back through the valve before the disc can shut off. To effect complete shut off, the disc of a swing check valve must travel through a 90 angle arc to the swing check valve seat.
