ProControl Regulator Features

The Humphrey ProControl Series, Electronic Pressure Regulators provide outstanding performance, versatility and value. Designed for low volume flow rates (PCRL) or high volume flow rates (PCRH), ProControl regulators precisely sustain outlet pressure, even during dynamic changes in downstream flow rates.

  • Two frictionless proportional valves control both fill and venting functions.
  • Two sizes: Low flow and high flow types.
  • Quiet operation, particularly at low pressure settings.
  • Relieving regulator type is standard (plug vent port for non-relieving)
  • Frictionless design results in multi-million cycle life.
  • Made in the USA.
  • RoHS and REACH compliant.

Typical applications:

  • Direct control of pressurized air and inert gases (consult factory for special gases and liquids)
