QPV High Resolution Pressure Regulator
QPV ultra high resolution electro-pneumatic closed-loop proportional pressure control valves are ideal for very sensitive applications such as leak testing at low pressures, dispensing and microfluidics flow control.
- Can be calibrated as low as 0-2 inches of water column
- Resolution (pressure steps) as high as ±0.005% of full scale calibration in single loop configuration
- Ideal for constant, low-flow applications too
QPV pressure regulators use a variable orifice valve, 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.
