Achieve Efficiency with Humphrey’s Proportional Valve Driver

Proportional valve drivers offer precise control of proportional solenoid valves in pneumatic applications. The device is convenient for valve testing and evaluation, or for use as a control input interface on fixtures in production.

Basic Features of Proportional Valve Drivers

Humphrey Products’ PCD proportional valve driver is designed to interface with PLCs, IoTs and closed loop systems to control proportional solenoid valves, or to be used manually when testing and evaluating valves.

Humphrey PCD features include:

  • Control input choices: 0-5v, 0-10v, 4-20mA or manual
  • Presets for Humphrey PV3, PV10, PC30 and Servoid proportional models
  • A screwless, push-to-connect wire terminals
  • Real Time LCD Display
  • Signal linearization
  • Handheld design
