Application range of sanitary diaphragm valve

The diaphragm valve can be operated remotely via a pneumatic head or manually via a handle. It is very suitable for the control and on/off tasks of pipeline fluid. It is widely used in sanitary brewing, dairy products, beverages and other food industries as well as in the pharmaceutical field under aseptic conditions.

Working principle of sanitary diaphragm:

◎The valve can be operated manually or pneumatically, and the sanitary diaphragm valve can also be controlled by a controller and solenoid valve.

◎The relationship between the valve body and the pressure plate prevents the compression of the diaphragm.

◎When the valve is closed, the pressure pad supporting the diaphragm moves toward the sealing surface on the valve body. When the pressure plate moves, the diaphragm bends and is forced to push toward the valve seat area in the center of the valve body, thus closing the fluid path to the valve body.
