Straight through the diaphragm valve is a special kind of block valves, dedicated to control of corrosive or general corrosive medium, the valve body cavity surface without lining or covered with a selection of all kinds of rubber, because the fluid channel straight through the diaphragm valve is straight, so fluid loss smaller, less wear is particularly suited to some fluid viscous fluid, slurry and precipitation.

Straight through the diaphragm valve structure features:
    1, straight through the diaphragm valve diaphragm replaceable, low maintenance cost;
    2, the diversity of the lining material, can be applied to a variety of media, and have the characteristics of high strength, good corrosion resistance.
    3, straight through the opening of the elastic diaphragm valve sealing parts, ensure no leakage;
    4, streamlined flow channel, small pressure loss;
    5, no stuffing box, so there is no leakage;

    6, straight through the diaphragm valve body and cover are intermediate diaphragm is separated, that at the top of the diaphragm valve cover, stem and other parts are not eroded by the medium.
