  • in Air Control/Relief Valves

    Proportion-Air, Inc. offers QL3 high resolution pressure control valves. These valves have pressure ranges from 0 to 165 PSIG, supply ranges from 15 to 24 VDC, operating temperatures ranging from 32 to 158°F, and an IP65/NEMA 4 protection rating. These valves are constructed from aluminum, stainless steel, Buna-N, Viton, brass, and nickel plating materials.

  • in Control/Relief Valves

    Proportion Air makes pneumatic pressure control valves, including electro-pneumatic valves, closed loop valves, high flow valves, and high resolution valves. Their high res control valves have a pressure range of 0 to 150psig with output pressure from 0-100% of the range and 40 micron actual filtration, and wetted elastomers made of Buna N, an aluminum nickel plated manifold, and Utem 1000 aluminum P. transducer.

  • in Pneumatic Valves

    Proportion-Air manufactures the packaged F-Series FCV, a proportional flow control valve that consists of an electronic pneumatic positioner, a pneumatic valve actuator, an LVDT position sensor to continuously monitor valve position, an angle seat valve, and a parabolic shaped linear valve trim. These valves fit pipe sizes from 0.25" to 1.5", and permit flow ranges from as low as 1-20 scfh to 25-250 scfm. The company's basic flow control valve allows a maximum Cv of 19, as well as an integral closed-loop position with +/-0.3% F.S. resolution; analog outputs of 0-10 Vdc and 4-20 mA are available.
