The name of the Diaphragm valve comes from a flexible disc which comes into contact with a seat at the top of the valve body to form a seal. A diaphragm is a flexible, pressure responsive element that transmits force to open, close or control a valve. Diaphragm valves are connected into a variety of piping systems.
Diaphragm valves are especially suited for handling corrosive fluids, fibrous slurries, radioactive fluids, or other fluids that must remain free from contamination. Since the diaphragm does not come into contact with the media the valve can be used with sticky or viscous fluids, which means they won't get stuck or clog other types of valve mechanisms.
Diaphragm valves have a very basic body construction. It contains stem, bonnet, compressor, lever, actuator.
Diaphragms can be made from a variety of materials. The material choice is based on the nature of the material handled, temperature, pressure, and frequency of operation.
Diaphragm valve bodies can be made of materials are plastic lined, rubber lined, glass lined, various solid metals and alloys, and solid plastic. They are less expensive because only the body and diaphragm need to be chemically compatible with the system media since the rest of the valve components are sealed from the system.
