Two loop, high resolution pressure control, +/-0.005% F.S.
Proportional inlet valve avoids digital stepping
Control pressure range from vacuum to 150 psig
QPV2 accepts feedback signal from F-Series (flow transducer)
closed loop flow control
Field adjustable deadband & stability to optimize performance
Variety of command signal options
Ultra High Resolution electro-pneumatic closed loop proportional pressure control valves. Two loop version accepts a feedback from wide ranges of external sensors. The QPV utilizes a variable orifice valve on the inlet side which eliminates the digital steps of traditional ON/OFF solenoid: The field adjustable hysteresis potentiometer allows users to virtually eliminate the dead-band of the control circuit, resulting in superior system resolution. Ideal for very sensitive applications such leak testing at low pressures and dispensing applications.
