  • WCB Diaphragm Valve, DN50, PN10, BS 5156, RF

    A diaphragm valve is equipped with a flexible diaphragm or a combination diaphragm inside the valve body and valve cover. Its closing element is a compression device connected to the diaphragm. Its structure is significantly different from that of conventional valves, making it a special form of a cut-off valve. The opening and closing element consists of a steel valve disc and a soft material (a composite of rubber and fluoroplastic) diaphragm, which separates the valve body cavity to achieve the purpose of cutting off the medium in the pipe.
