Ductile Iron PN16 Flanged Check Valve is a valve whose opening and closing parts are opened or closed by the force of the flow of the medium to prevent the medium from flowing back. The check valve only allows the medium to flow in one direction and prevents the flow in the opposite direction. Usually this kind of valve works automatically. Under the action of the fluid pressure flowing in one direction, the valve flap opens; when the fluid flows in the opposite direction, the fluid pressure and the self-coincidence of the valve flap act on the valve seat, thereby cutting off the flow. It is mainly used in pipelines where the medium flows in one direction, and only allows the medium to flow in one direction to prevent accidents.
