Lining fluorine rubber diaphragm valve is a special form of truncation function of the valve, the opening and closing by steel disc with soft material (rubber and fluorine plastic compound) of diaphragm, and the valve body cavity with the valve cover the inner chamber is separated to truncate the tube medium.

Features:
    1. The composite diaphragm in the lower part of the body cavity with the valve cover inner chamber is separated, and the formation of dc channel, make the diaphragm of the upper stem and disc on a completely isolated from medium, save packing seal structure, the medium of leakage and leakage can be avoided.
    2. The use of FEP (Teflon) of fluorine plastics and synthetic rubber compound with Feflon fluorine plastic lining layer of the diaphragm and the valve can be suitable for except the molten alkali metal, elements, fluorine of strong corrosive medium.
    3. The diaphragm due to frequent components as the implementation of the opening and closing easy to produce fatigue fracture, should be replaced periodically depending on working condition, medium characteristics.

    4. The fluorine plastic anti-corrosion performance and it is recommended to use temperature see "valves and pipe fittings with fluorine plastic lining performance table".
