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.

Like most of our products, the QPV can be modified in numerous ways to meet the most demanding applications. Customizations may change the price of the product. Get a quote for a product customized to your exact needs using the Request Quote tab below.
