High Flow Electronic Pressure Control Now in High Density Manifold Mount
The Proportion-Air QB3 control valve has long been an industry leading product when electronic pressure control of high flow rates is needed. Traditional applications are pneumatic cylinder force control or spray pattern control. Now users can improve space efficiency by manifold mounting the QB3 electronic pressure regulator on a high density space saving manifold. All models of QB3 control valve may be manifold mounted, including vacuum control, vacuum through positive pressure, absolute pressure, and standard gauge pressure models.
o Electronically control pressure ranges from vacuum to 150 psig
o Accuracy +/-0.25% F.S.
o High forward and reverse flow up to 20 SCFM
o 0-10Vdc differential or 4-20mA differential command signal
o Variety of wetted elastomers
o 0-10Vdc or 4-20mA analog monitor output
o Very rugged design with long life
o Available with integral digital display panel meter
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. the pressure transducer is connected directly to the control pressure so the closed loop electronics and analog monitor signal show you what is really happening in your process.
