- 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 microns 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. An optional digital display is available.
