Our Complete Line of Pilot Operated Regulators
We have a wide range of air pilot operated regulators to choose from that we can match to your demanding application requirements. Your pilot operated regulator can be selected by our experienced application engineers, with your input in mind. Proportion-Air offers pilot operated pressure reducing valves (also known as volume boosters), pilot operated back pressure control valves (BPVs), pilot-operated ratio regulators, low-pressure pilot operated regulators, high-pressure pilot operated regulators, vacuum regulators, and high relief flow (with high exhaust) pilot operated regulators.
General Duty, Low Cost
The PSR-series air pilot operated regulators handle most industrial shop air applications. The PSR is a low cost air volume booster which converts an air pilot signal pressure into a high flow output pressure. This is a self relieving regulator, so pressure can be controlled forward and reverse. The PSR pneumatic regulator is one of Proportion-Air’s most widely used pilot operated regulators and is a great match with the QB series of electronic pilot regulators.
High Performance Pressure Regulators
The RM-series is at its best with the most demanding applications. The RM pilot operated regulators have great forward flow capabilities and very high relief flow for when maximum exhaust speed is required. The RM pneumatic regulator series is a rugged and dirt tolerant design made for industrial environments. The RM can control pressures higher than standard shop air systems and because of its quick exhaust design, the RM pilot operated regulator is very useful when controlling vacuum or absolute pressures.
High Performance, High Flow
The R-Series volume boosters are diaphragm operated, air piloted, self-venting regulators. They are designed for general applications that require superior pressure regulation, rapid response to changing flow demands, and excellent stability. Using QB series pressure controllers in conjunction with the R-Series volume booster gives a precision pressure control package with high forward and reverse flow capacity. The R-Series volume boosters can also be used in vacuum applications where high flow and precise vacuum control is required.
RV Series Vacuum Control Regulators
The Proportion-Air RV series is a dedicated vacuum pressure control valve. The RV is a pilot operated valve and is a great match with Proportion-Air’s full line of electronic pilot valves such as the QB1 and QB2 electronic regulators. The RV controls vacuum quickly by mechanically matching the pilot operation signal to the high flow controlled output vacuum port. High flow rates of vacuum are quickly and accurately controlled.
High Performance at Low Pressures
The RG-Series of pilot operated regulators fits all the places where standard catalog pressure regulators fall short. The RG-Series is available as a volume booster in very low pressure applications or as ratio operated regulators for very high pressures. Most nonstandard applications can be matched to an RG pilot operated regulator. All RGs are able to be pilot operated with Proportion-Air’s electronic air pressure control valves. Paired with the Proportion-Air QPV, the RG provides excellent resolution at low pressure when high flow is required.
Heavy Duty, up to 8″ Flanged
[formerly the HP-Series] The PABD-Series pilot operated (dome-loaded) regulators are used for high pressures and other high demand process applications. The PABD-Series pilot regulators are available from 1/2″ NPT up to 8″ flanges with a variety of materials for very high flows. The PABD is excellent for controlling the temperature of saturated steam.
Proportion-Air has carefully selected and tested a wide variety of pilot operated regulators. Proportion-Air’s long experience with volume boosters and other pilot operated regulators lets us carefully select a proven model that is a perfect match for your pneumatic regulator application.
What Our Customers Say
What an excellent process you have for specifying parts for your customers. I am very impressed.
I met with Bill today...He was impressed by your knowledge and application of your products and wanted me to thank you for your excellent support.
It is really a pleasure to work with Proportion-Air. You cannot imagine what kind of problems I have with some manufacturers. Thank you very much!
I'm astonished for the quickest answer ever!
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.
