PSR pilot operated regulators are dome-loaded, self-venting volume boosters ideal for pairing 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 handle most industrial shop air applications. The PSR is a cost effective 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.
