Resilient Seated Flanged Ends Swing Check Valve

Products Details

What is the Flanged swing check valve？

Flanged swing check valve is swing type check valve (non-return valve) with flanged connection. It is used to allow water to flow through it in only one direction, and the disc swings off the seat to permit forward flow, or swing on the seat to block reverse flow.The swing check valve is a kind of check valve that the valve flap opens and closes with the upward rotation of the rocker arm, which can automatically prevent the backflow of the fluid. The disc of the check valve swings upward under the action of fluid pressure, and the fluid flows from the inlet side to the outlet side. When the pressure on the inlet side is lower than that on the outlet side, the valve disc will automatically close under the action of fluid pressure difference, gravity and other factors to prevent the fluid from flowing back.
