QPV Low Pressure Valve Series
Brand: Proportion-Air, IncUltra High Resolution electro-pneumatic closed-loop proportional pressure control valves.
The QPV pressure control valve utilizes a variable orifice valve on the inlet side, which eliminates the digital steps of traditional ON/OFF solenoids: 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 as leak testing at low pressures, dispensing and microfluidics flow control.
The QPV-Series pressure control valve can provide resolutions (pressure steps) as high as ±0.005% of full scale calibration in single loop configuration.
The QPV can be calibrated as low as 0-2 Inches of Water Column or any calibration from full vacuum to 150 PSI.
