What Are The Applications And Working Principles Of Sanitary Diaphragm Valves?

Sanitary Diaphragm Valve can be operated remotely by a pneumatic head or manually by a handle. It is very suitable for the control and opening/closing tasks of pipeline fluid. So do you know what are the applications and working principles of sanitary diaphragm valves?

The working principle of sanitary diaphragm valve is as follows:

The close fit between the valve body and the diaphragm of the sanitary diaphragm valve provides valve body sealing and valve seat sealing, ensuring the isolation of the internal and external environments of the pipeline, so the valve is suitable for aseptic processes.

The opening and closing of the sanitary diaphragm valve is achieved by the up and down movement of the valve stem. When the valve stem is in the upper position, the spherical diaphragm bends upward to form a conducting state. When the valve stem moves from top to bottom, it drives the valve core to bend the diaphragm, forcing the diaphragm to be close to the valve seat area or, closing the path to the pipeline fluid.

Sanitary diaphragm valves are widely used in sanitary brewing, dairy products, beverages and other food industries as well as in the pharmaceutical field under aseptic conditions.
