Proportion-Air Closed Loop Pressure Control

QB1X/QB2X

• Pressure Range: Full vacuum to 175 psig
• Accuracy/Repeatability: +/- .2%  F.S /+/- .02% F.S
• Max Flow: 1.2 scfm
• 1/8” NPT Ports

QB1X & QB2X electro-pneumatic closed loop pressure control valves are in a compact IP65 rated 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. It is available with either aluminum or 303 stainless steel manifold.

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.

MM1/MM2

• Pressure Range: Full vacuum to 175 psig

• Accuracy/Repeatability: +/- .2%  F.S /+/- .02% F.S
• Max Flow: 1.2 scfm
• 1/8” NPT Ports

MM1 & MM2 electro-pneumatic closed loop air pressure control valves are available with DIN rail, panel mount or up to 12 station sub-base manifold mounting. Analog monitor output is standard, select 0-10 VDC or 4-20 mA. Jumper selectable command 0-10 VDC or 4-20 mA.

Common supply and exhaust ports on sub-base manifold for easy plumbing. Adjustable dead band allows field tuning of system stability. The dual loop design accepts feedback signal from a wide range of external sensors.
