Humphrey Pressure Regulators
Humphrey features the ProControl™ Electronic Pressure Regulators to provide exceptional closed-loop downstream pressure control.
Incorporating a dual proportional valve approach, the analog circuitry compensates for dynamic changes in downstream pressure. Our exceptional design controls input compressed air pressure to its exact desired output pressure.
Humphrey Electronic Pressure Regulators boast:
- Improved responsiveness for changes with inlet and outlet pressures
- Quiet operation, ideal medical and laboratory applications
- Extended service life when compared to competitive models
- Superior performance versus regulators with ON/OFF venting valves
Additionally, Humphrey offers a miniature pressure regulator to compliment their TAC Series Pneumatic Logic Component lineup.
ProControl Electronic Pressure Regulators
The direct-acting PCRL low flow electronic pressure regulator maintains precise downstream pressure in dynamic upstream and downstream applications.
The pilot operated PCRH high flow regulator can maintain downstream pressure with flows up 600 LPM.
ProControl™ Regulators feature proportional venting valves to eliminate high cycle rates of ON/OFF venting valves, providing:
- Excellent resolution
- Extended product life
- Noise reduction
Humphrey’s electronic pressure regulators are available with various levels of LPM flow capacity. All models provide three ports for air and inert gases.
