ProControl™ Proportional Control Solenoid Valves

Humphrey ProControl™ Series of proportional solenoid valves deliver variable precise output flow from a corresponding input current to its solenoid.

The line-up features new and improved miniature PV3 and PV10 models in 10-32 UNF port size and now spans six models up through 1/4 PIPE and flow capacities to 225 SLPM. Utilizing a flat spring armature design, customers can expect precise flow control capability, repeatable performance over millions of cycles and high turn-down ratios.

With selectable, incremental or dynamic control of media flow, ProControl™ Proportional Valves can be applied to market segments such as:

  • Medical
  • Analytical
  • Testing
  • Instrumentation
  • Factory and process automation
