About Diaphragm Valve

Diaphragm valves (or membrane valves) consists of a valve body with two or more ports, an elastomeric diaphragm, and a "weir or saddle" or seat upon which the diaphragm closes the valve. The valve body may be constructed from plastic, metal, wood or other materials depending on the intended use.

Actuators

Diaphragm valves can be controlled by various types of actuators e.g. manual, pneumatic, hydraulic, electric etc. The most common diaphragm valves use pneumatic actuators; in this type of valve, air pressure is applied through a pilot valve into the actuator which in turn raises the diaphragm and opens the valve. This type of valve is one of the more common valves used in operations where valve speed is a necessity.

Hydraulic diaphragm valves also exist for higher pressure and lower speed operations. Many diaphragm valves are also controlled manually.

Applications

Diaphragm Valves are ideally suited for:

  • Corrosive applications, where the body and diaphragm materials can be chosen for chemical compatibility. (E.G. Acids, Bases etc.)
  • Abrasive applications, where the body lining can be designed to withstand abrasion and the diaphragm can be easily replaced once worn out
  • Solids entrained liquids, since the diaphragm can seal around any entrained solids and provide positive seal
  • Slurries, since the diaphragm can seal around entrained solids and provide positive seal

The air actuator does not have a manual override, but a manual override is provided with optional direct mount solenoid valves.
See product specifications. Generally, smaller valves less than 2 inch pipe size, cycle in about one second. Larger valves up to 6 inch pipe, cycle in about 1.5 seconds. A cycle is per 90° rotation
