Low Pressure Valves
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.
2 inches of water column = 0.072 PSI
A 0-2″ H2O full scale calibration and accuracy of ±0.2%, equates to an accuracy of ±0.0001 PSI throughout the entire calibrated range.
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%.
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. We also want to understand your application so you do not waste your time testing products that may (or may not) meet your needs.
