Epdm Lined Wafer Dual Check Valve

     Check valves can also be used to supply lines in which the pressure may rise to an auxiliary system that exceeds the system pressure. Check valves can be divided into rotating check valves (rotating according to the center of gravity) and lifting check valves (moving along the axis). The function of this type of valve is to allow only the medium to flow in one direction and to prevent the flow in the opposite direction. Usually this valve works automatically, and the disc opens under the action of fluid pressure in one direction; when the fluid flows in the opposite direction, the fluid pressure and disc self-reclosing disc act on the seat, thus cutting off the flow.
