How Does A Sanitary Diaphragm Valve Work?

Sanitary Diaphragm Valve can be operated remotely by a pneumatic head or manually by a handle. So do you know how sanitary diaphragm valves work?

Working principle of sanitary diaphragm valves:

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.

The sanitary diaphragm valve is a form of shut-off valve, and its opening and closing part is a diaphragm made of soft material, which separates the inner cavity of the valve body from the inner cavity of the valve cover.
