3/8" Relieving Regulator – 208 SCFM | 5–150 PSI

Description

3/8" Relieving Regulator – 208 SCFM | 5–150 PSI

Product #: MCR74-38

When airflow demand increases, pressure control becomes even more critical. The MCR74-38 3/8" Relieving Regulator delivers high-capacity performance with precise, stable outlet pressure control for demanding pneumatic systems.

Built to maintain steady downstream pressure regardless of inlet fluctuations, this regulator protects tools, cylinders, automation components, and production equipment from damaging spikes and inconsistent air delivery.

As a relieving-style regulator, it automatically vents excess downstream pressure when the system is dead-ended. This allows safe and accurate pressure reduction without manual bleed-off, ensuring smooth adjustments and controlled system performance.

With an impressive 208 SCFM flow capacity, this unit supports higher air consumption applications while maintaining dependable regulation.

Important Installation Note

A pressure gauge is required for proper pressure monitoring and adjustment.
The regulator includes dual full-flow gauge ports to allow flexible gauge placement.
