Product Description

Cast Ductile Iron Wafer Type Duplex Butterfly Double Door Disc Dual Plate/Flap/ Swing Check Valve
 

Product Description

Check valves can be mainly divided into swing check valves (rotating according to the center of gravity) and lifting check valves (moving along the axis). The function of that check valve is to only allow the medium to flow in one direction and prevent the medium from flow in the opposite direction. Usually, this kind of valve works automatically. Under the action of fluid pressure flowing in one direction, the disc opens. When the fluid flows in the opposite direction, the fluid pressure and the self-overlapping disc of the disc act on the valve seat, thus cutting off the flow.
