Diaphragm valve is a special form of valve with cut-off function. Its opening and closing parts are composed of a diaphragm made of steel valve disc and soft materials (rubber and fluoroplastic composite), and the valve body cavity is separated from the valve cover cavity to achieve the purpose of cut-off the medium inside the pipe.

The basic series of diaphragm valves are G41F46 weir type and G45F46 DC type. The structural characteristics are as follows:

(1) The composite diaphragm separates the lower inner cavity of the valve body from the inner cavity of the valve cover, and forms a direct current channel with it, completely isolating the valve stem, valve disc and other internal components on the upper part of the diaphragm from the medium, eliminating the need for packing sealing structure, and avoiding both internal and external leakage of the medium.

(2) Using FEP (Teflon) fluoroplastics and synthetic rubber composite membranes, customers can choose different lining materials according to the requirements of the medium to maximize economic benefits.

(3) As an actuator, the diaphragm is prone to fatigue fracture due to frequent opening and closing, and should be replaced regularly according to the working conditions and medium characteristics.
