Proportional solenoid valve provides variable flow control for compressed air or inert gas by corresponding input current (amperes).

 

Humphrey ProControl proportional valves are available in 5 sizes: 1) low lag, 2) excellent adjustment ratio, 3) cyclic repeatability, 4) into the "Servoid" series to provide precise flow control in the large flow range, 5) the new PV3 to provide PV10 micro series.

 

Please consider the convenient PCD proportional valve driver. Generate appropriate current control to drive any proportional valves (<1 amp) based on signals from the data acquisition source or the PCD manual roller.

 

The main use of ProControl valves to control flow:

 

* Dynamic - continuous high frequency adjustment (closed loop response),

 

* Increment - Make predetermined low frequency adjustments within each cycle,

 

* Cycle - According to the regulations, the output flow can be selected per cycle.
