Introduction A sanitary diaphragm valve is composed of a sanitary diaphragm and a pneumatic actuator, which is powered by compressed air to regulate the flow of fluid medium in the processing pipeline. Structure The structure of the sanitary diaphragm valve is very different from the general valve structure. It relies on a soft rubber membrane or plastic membrane to control the fluid movement. Commonly used diaphragm valve materials are divided into cast iron diaphragm valve, cast steel diaphragm valve, stainless steel diaphragm valve, and sanitary diaphragm valve material diaphragm valve. Principle The closing and opening of the sanitary diaphragm valve are achieved by the pressure from the pipeline acting on…
