A diaphragm valve
is a type of valve that uses a flexible diaphragm to control the flow of fluid through the valve. The diaphragm is typically made of a rubber or elastomeric material and is placed between the valve body and a compressor. When the compressor is activated, the diaphragm is pressed against the valve body, sealing the valve and preventing fluid from flowing through. When the compressor is released, the diaphragm relaxes and allows fluid to pass through the valve.
Diaphragm valves are often used in applications where a high level of precision and control is needed, such as in pharmaceutical, food and beverage, and biotech industries. They can be used for both on/off and throttling applications, and are particularly useful for handling corrosive, abrasive, or viscous fluids. They are also commonly used in applications where contamination must be minimized or eliminated, as the diaphragm provides a sterile barrier between the fluid and the valve body.
