ヤフラム弁。 In manual diaphragm valves, which keep the inside of the valve box clean by separating the inside of the valve box and the valve opening/closing operation part by a diaphragm, the rotation of the valve handle is converted into linear motion to raise and lower the valve stem for opening and closing the valve. A square-hole push screw is installed in the center of the valve stem push-down screw to eliminate the gap created between the upper end surface of the internal assembly including the valve stem and the engaging surface of the valve stem push-down screw that holds the steel ball. A manual diaphragm valve characterized in that the diaphragm valve is removed at the final stage of assembly.
