    Description

    Straight Through Diaphragm Valve

    Straight Through Diaphragm Valves is used to control non corrosive or general corrosive medium. The inner cavity surface of the valve body is unlined or covered with various kinds of rubber, suitable for different working temperature and liquid pipeline. Diaphragm valve is a special type of truncation valve, flexible seal open and closed, to ensure no leakage, streamlined flow channel, so that the pressure loss is small, no packing letter, so there is no leakage, the valve body and cover are separated by the middle diaphragm, so that the valve cover above the diaphragm, the valve stem and other zero parts are not eroded by the medium and the diaphragm can be replaced, The maintenance cost is low, the lining material is diverse, it can be applied to all kinds of media, and has the characteristics of high strength and good corrosion resistance.
