One Piece Body Wafer Dual Plate Check Valve

The function of Wafer Dual Plate Check Valve is to only allow the medium to flow in one direction and prevent the flow in the opposite direction. Usually, this type of valve works automatically, and under the pressure of fluid flowing in one direction, the valve disc opens; When the fluid flows in the opposite direction, the pressure of the fluid and the self weight of the valve disc act on the valve seat, thereby cutting off the flow.
