Product Announcement from Proportion-Air, Inc.
QPV1 Electro-pneumatic Proportional Control Valve
- Single loop, high resolution pressure control, +/-0.005% F.S.
- Proportional inlet valve avoids digital stepping
- Control pressure range from vacuum to 150 psig
- Field adjustable deadband & stability to optimize performance
- Variety of command signal options
Ultra High Resolution electro-pneumatic closed loop proportional pressure control valves. 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.
