QB1S/QB2S

  • Pressure Range: Full vacuum to 500 psig
  • Accuracy/Repeatability: +/- .25%  F.S /+/- .05% F.S
  • Max Flow: 1.2 scfm
  • 1/8” NPT Ports

QB1S & QB2S electro-pneumatic closed loop air pressure control valve are in a compact package in 1P65 housing.  Analog monitor output is standard, select 0-10 VDC or 4-20 mA. The dual loop accepts feedback from signal from a wide range of external sensors.

Either unit is unaffected by mounting position or vibrations to 25Gs.  They operate with standard industrial air filtered to 40 micron while not consuming air in a steady state, reducing operating cost.

These units can be assembled to an air pilot regulator (volume booster) for higher flows up to 3,000 SCFM, higher pressures to 7,000 psig and control of various gaseous and liquid media. Optional digital display is available.

QB3

  • Pressure Range: Full vacuum to 150 psig
  • Accuracy/Repeatability: +/- .25%  F.S /+/- .2% F.S
  • Max Flow: 30 scfm
  • ¼” NPT Ports

The QB3 is a complete electronic pressure regulator package consisting of two feed and bleed solenoid valves, a control circuit, a pressure transducer, an integral air pilot operated volume booster and a rugged IP65 housing.
Analog monitor output is standard, select 0-10 VDC or 4-20 mA.  Select 0-10 VDC or 4-20 mA differential command signal.

Available options include digital display, manifold mount, a variety of wetted elastomers and brass body version cleaned for oxygen service.

QB3H

  • Pressure Range: Full vacuum to 500 psig
  • Accuracy/Repeatability: +/- .5%  F.S /+/- .2% F.S
  • Max Flow: 50 scfm
  • 3/8” NPT Ports

QB3H electronic pressure regulator consists of two solenoid valves which add or subtract pressure to the pilot of an integral volume boosting regulator. An internal stainless steel pressure sensor measures the high pressure output of the integral volume booster and send this signal to the on-board controller.

Available in lightweight aluminum, stainless steel or oxygen service compatible brass bodies.
