How Does A Sanitary Diaphragm Valve Work?

Sanitary Diaphragm Valve has the advantages of simple structure, beautiful shape, quick disassembly and assembly, flexible operation, small fluid resistance, and reliable use. So do you know what are the working principles of sanitary diaphragm valves?

Working principle of sanitary diaphragm valve:

Sanitary diaphragm valves can be operated manually, pneumatically, or controlled by an intelligent controller. 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 the valve upward to form a conductive 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 suitable for water, gas, oil and corrosion in chemical, petroleum, metallurgy, water heating, food, medicine and other industries.
