Newsway Valve Heavy hammer check valve adds the weight handle and weight design and manufacturing to the linkage between the valve flap and the stem of the ordinary check valve. When no medium passes through the valve body, the valve flap, weight handle and weight and other components Under the action of gravity, it rotates around the valve stem to make the valve flap contact with the valve seat to form a seal, so as to achieve the purpose of closing the valve; while the medium passes, the medium will push the valve flap, the weight handle and the weight and other components around the valve The rotation of the rod separates the valve flap from the valve seat to release the seal, so as to achieve the purpose of opening the valve.
