About Proportion-Air
Being the global leader in proportional electro-pneumatic pressure and flow control, these three words – accurate, repeatable, customizable – are what set us apart from our competition. We focus on meeting your exact needs for precise, repeatable control and build a proportional pressure or flow device to match them.
And we make it possible to go beyond “global” – Our clients in the aerospace industry can tell you how integral our products are for leaving our atmosphere.
History
Proportion-Air, Inc. began as a manufacturer of proportional electronic air pressure regulators and air flow control valves. The company was founded in 1985 by corporate president Daniel E. Cook to capitalize on the sales and marketing prospects of the unique invention of an electronic air pressure regulator.
This air pressure device was designed to accept a variety of electronic analog and digital signals in order to control pneumatic pressures with extreme accuracy while negating the effects of vibration, mounting position or environmental concerns.
What is Air Pressure Regulation?
Today, our family of brands includes Burling Valve industrial process regulators and Protect-Air USA miniature safety regulators and air fuses.

Where Others Fear to Tread
Proportion-Air goes where others fear to tread: vacuum control, vacuum through positive pressure, absolute pressure, inches of water column and direct control up to 1,000 psi. This variety of outputs can be controlled by an equally diverse range of electrical inputs including analog, digital and serial communications.
Our years of engineering and design experience give us the confidence to take on the most problematic and exacting applications.
Advanced Technology
Proportion-Air handles these difficult requirements with unique advanced control technology, resulting in products with superior accuracy, resolution, and repeatability. This refinement of performance doesn’t mean they’re delicate. All Proportion-Air products are built tough to handle the most adverse environments. Proportion-Air’s advanced “dual loop” technology allows closed loop control using many different downstream sensors in order to control many different processes and applications.
The People at Proportion-Air
Proportion-Air’s biggest asset has always been its people. Many companies offer some similar products, but you can’t get a straight answer when you call them. Proportion-Air not only offers superior products, but it has the people to back up those products. Our focus is electronic control of pressure and flow and this focus shows in our products.
