Proportional solenoid valves have direct-acting control valves with linear characteristics. Proportional solenoid valves control accuracy, hysteresis, and repeatability within close tolerances. Proportional solenoid valves are used for automatic gas flow control of gas chromatographs and other analyzers, as well as for precision control of pressure. These valves feature relatively low energy consumption and eliminate flow fluctuations.
There are two general types of proportional solenoid valves: direct-acting and pilot-operated. Direct-acting proportional solenoid valves have a plunger that is in direct contact with the primary opening in the body. This plunger is used to open and close the orifice. The pilot-operated proportional solenoid valve, in comparison, works with a diaphragm rather than a plunger. This valve uses differential pressure to control the flow of fluids. The air-venting valve opens to allow the pressure to equalize and permit the fluids to flow through.
