PSR Pilot Operated Regulators | General Purpose
PSR pilot operated regulators are dome-loaded, self-venting volume boosters that function as a slave regulator when mated with our QB-Series electronic pressure regulators. The PSR provides a controlled pressure with much higher flow rates than can be achieved through the QB products alone. PSR pilot operated regulators can handle any inert gas or they can be adapted for use with natural gas, propane or oxygen.

General Duty, Low Cost
PSR pilot operated regulators handle most industrial shop air applications. The PSR is a low cost air volume booster that 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.
