Low Cost Valves & Electronic Pressure Regulators

Proportion-Air’s pressure and flow controllers are never the lowest initial purchase price, but our products are always the lowest cost of ownership in the long run. We often come across our low cost valves in the field. Many times these products have been in operation for 20+ years! This is certainly not something we guarantee, but we are not surprised when it happens. Our low cost valves can be this durable because of our process, which seeks to understand the application and specify the correct product for the job.


– The Best Low Cost Valves are not always the least expensive –

Too often, electronic pressure regulators get misused and poorly specified. If we understand your application, we can specify a product that will perform the best and the longest.


We offer electronic pressure controls to meet every budget. Our low cost valves and electronic pressure regulators are carefully selected with your input, individually hand built and calibrated at our factory in McCordsville, Indiana and backed by real people when you need to pick up the phone.

    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.
