Modulating Diaphragm Valve
Modulating Diaphragm Valve is used to change the passage section and the flow direction of the medium, and has the functions of diversion, cut-off, adjustment, throttling, check, diversion or overflow. Valves can be used to control the flow of fluids such as water, steam, oil, gas, mud, various corrosive media, liquid metals and radioactive fluids.
Modulating Diaphragm Valve Basic Character:
Three way （3 way）diaphragm valve is specially used to control non-corrosive or general corrosive media. The surface of the valve body is unlined or lined with various rubbers for selection. It is suitable for different working temperatures and fluid pipelines. The variety of lining materials can be applied to various media and has good corrosion resistance. The valve body and the cover are separated by the intermediate diaphragm, so that the valve cover and the valve stem parts above the diaphragm are not eroded by the medium. The diaphragm valve is a special form of globe valve.
