1/2" Relieving Regulator – 220 SCFM | 5–150 PSI

Description

1/2" Relieving Regulator – 220 SCFM | 5–150 PSI

Product #: MCR74-50

In a compressed air system, pressure is either controlled… or it’s in control of you. The 1/2" MCR74-50 Relieving Regulator keeps your downstream equipment protected by delivering stable, repeatable outlet pressure even when inlet conditions fluctuate.

Designed to maintain consistent pressure regardless of upstream swings, this regulator is ideal for protecting tools, valves, cylinders, and production equipment from pressure spikes that cause wear, inconsistency, and downtime.

Because this is a relieving-style regulator, it automatically vents excess downstream pressure when the system is dead-ended. That means if outlet pressure needs to be reduced, the regulator handles it internally without requiring manual bleeding. Clean, controlled, precise.

With a 220 SCFM flow rating, it supports substantial air demand in industrial applications without becoming a bottleneck.

Important Note

A pressure gauge is required for proper operation and monitoring.
The regulator includes dual full-flow gauge ports to accommodate installation.

Why Choose a Relieving Regulator?

• Maintains steady outlet pressure

• Compensates for inlet pressure fluctuations

• Automatically vents excess downstream pressure

• Protects pneumatic tools and automation equipment

• Improves production consistency

If your application requires pressure adjustments without shutdown or manual bleed-off, a relieving regulator is the correct solution.

Recommended Accessories

For proper installation and monitoring, we recommend:

• • Back Mounted Pressure Gauge – LSCB20-200

  • Wall Mounting Bracket – MC4324-50

These accessories ensure accurate pressure visibility and secure mounting in industrial environments.

The MCR74-50 is built for shops and facilities that demand controlled, reliable air delivery. Proper regulation is not optional in a professional compressed air system. It is foundational.
