3/4" Relieving Regulator – 220 SCFM | 5–150 PSI

Description

3/4" Relieving Regulator – 220 SCFM | 5–150 PSI

Product #: MCR74-75

When your system moves serious air, pressure control must keep pace. The MCR74-75 3/4" Relieving Regulator is built for higher-capacity compressed air applications that demand steady, dependable outlet pressure without fluctuation.

This regulator maintains a consistent downstream pressure regardless of inlet pressure swings, protecting tools, automation components, and production equipment from damaging overpressure and instability.

As a relieving-style regulator, it automatically vents excess downstream pressure when the system is dead-ended. That means you can reduce outlet pressure safely and accurately without manually bleeding the line. Clean adjustment. Controlled response. Reliable protection.

With a 220 SCFM flow rating, this 3/4" model is well-suited for main distribution drops and high-demand point-of-use stations.

Important Installation Note

A pressure gauge is required for proper monitoring and adjustment.
Dual full-flow 1/4" FNPT gauge ports are provided for flexible installation.
