Electronic Pressure Regulators

Proportion-Air electronic pressure valves are designed to be used as standalone pressure regulators or paired with the Burling Valve BD-Series of dome-loaded regulators for electronic control of the pressure setpoint. These devices can accept a variety of command signals including: mA, VDC, RS232, RS485, Ethernet and more. The command signal is linear and proportional to the pressure output and with the on-board PID controls, these products simply need a power supply and a command signal generator to operate.

QBX

Electronic Pressure Regulator

The QB1X is a complete closed-loop pressure control device consisting of 2 internal valves, manifold, housing and electronic controls. The inlet and outlet pressure is controlled by 2 on/off solenoid valves and the pressure output is measured by an on-board pressure transducer. The QB2X implements external feedback and is often used to pilot dome loaded regulators like Burling Valve's BD-Series.

ISF

Nonincendive Electronic Pressure Regulator

The ISF is a Factory Mutual rated Nonincendive (Class II, Division 2 Groups C, D) electo-pneumatic closed-loop pressure control valve. Offered with standard 4-20 mA analog command signal. The BVISF is internally potted and able to directly control hazardous media such as natural gas. It can be assembled to an air piloted regulator for high flow, higher pressures and various media control.

  • Pressure Range: Full Vac to 150 psig

  • Max Flow: 0.8 SCFM

  • Accuracy: +/- 0.5% F.S.

  • Repeatability: +/- 0.2% F.S.

  • Ports: 1/8" NPT

GX

High Pressure Electronic Pressure Regulator

The GX is a high pressure electro-pneumatic control valve offering 1:1 pressure control up to 1,000 PSIG without the need for a ratio amplifying booster. This series includes a power and status indicator LED and is field servicable with field modifiable command and monitor signals. 

  • Pressure Range: Full Vac to 1,000 psig

  • Max Flow: 26 SCFM @ 1,000 psig

  • Accuracy: +/- 0.25% F.S.

  • Repeatability: +/- 0.15% F.S.
