                Description of the operation principle and structure
                1, when the fluid along the direction of the arrow through the valve, because the valve flap fluid differential pressure rises, so that fluid smoothly through the valve
                2, when the fluid backflow, due to self weight and fluid valve differential pressure, so that the valve clack down and sealed with sealing surface to prevent fluid backflow.
                3, the valve is fully closed structure, no dynamic seal, never leakage.
                Four, the material of main parts:
                Parts name material
                The valve body valve cover of carbon steels WCB
                The valve sealing surface of 25# nylon 1010
                Flange bolt 35CrMoA
                The flange nut 35#
