Key features

Diaphragm valve is a special type of valve with cutoff function.

Its disc is composed of a diaphragm made of steel disc and soft materials(rubber and fluoroplastic composite),and separate the body inner cavity from the bonnet inner cavity.

When the handwheel is operated clockwise,the stem will move downward,and the disc will drive the diaphragm downward to cut off the passage,otherwise,the valve will open.

The composite membrane separates the lower inner cavity of the body from the inner cavity of the bonnet,and forms a DC channel with it,completely isolating the the stem,disc and other internals

The membrane made of FEP(Teflon) fluoroplastics and synthetic rubber and the valve with a (Teflon) fluoroplastic lining layer can be used for various highly corrosive medium.

As actuator,the diaphragm is prone to fatigue fracture due to frequent opening and closing.Therefore,it should be tested for working conditions,media,and characteristics,and replaced regularly.

Design Specification:Comply with HG/T 3704. GB/T 12224. ASME B16.34.

Drive mode :Manual, Pneumatic (normally open or normally closed ).Electric.
