Low Pressure Valves & Regulators

Proportion-Air leads the way in the electronic control of low to very low air pressures. Our electronic low pressure valves and regulators are used in many applications, from tank blanketing to dispensing to microfluidics. It is our ability to create a custom pressure range (tailored to your application) paired with our electrical knowledge that provides our customers the confidence in our low pressure valves.

We specialize in pressure ranges below 5 PSI, but we don’t stop there. Proportion-Air can offer products with a full scale calibration of 0 to 2 inches of water column with an accuracy of  ±0.2%.

2 inches of water column = 0.072 PSI.

This equates to an accuracy of ±0.0001 PSI throughout the entire calibrated range.

Most of our competitors expect you to understand the nuances of pneumatic control and choose a product off the shelf. We do not have product on the shelf, we build to your specifications (with lead times around 2 weeks). We also want to understand your application so you do not waste your time testing products that may (or may not) meet your needs.

    Alessio B. -Bologna, Italy

  • I'm happy to report that the trial on the QPV1 has been going well. I'm quite impressed by the performance of the unit. I'm also very impressed by the service that I received from Nick Archer which I think merits specific attention. Nick has been extremely responsive to my emails and questions. He has been patient, has kept his word, and has always replied to me quickly with an answer or a reply to my questions. Nick has provided me with what I, and certainly others in my group, consider to be a perfect example of top notch high quality customer service.
