G941F46 Electric Fluorine Lined Diaphragm Valve basic structure

1, The composite diaphragm separates the lower cavity of the valve body from the inner cavity of the bonnet and forms a direct current channel with it so as to completely separate the valve rod, the valve flap and other inner parts of the diaphragm from the medium, eliminating the need for the packing and sealing structure, Leakage and leakage can be avoided at the same time.

2, as the implementation of the components of the film due to frequent opening and closing easily produce fatigue fracture, should be treated as conditions, the periodic change of media properties.

3, the corrosion resistance of plastic and recommended temperature see "valve and pipe fittings plastic lining performance table.
