3/8" Relieving Regulator – 144 SCFM | 5–150 PSI
Product #: MCR73-38
In a compressed air system, pressure control is not optional. It is the difference between smooth production and premature equipment failure. The MCR73-38 3/8" Relieving Regulator is engineered to deliver steady, reliable outlet pressure even when inlet pressure fluctuates.
Designed to maintain consistent downstream pressure, this regulator protects tools, automation components, and pneumatic equipment from damaging spikes and instability.
Because it is a relieving-style regulator, it automatically vents excess downstream pressure when the system is dead-ended. That allows outlet pressure to be reduced safely and accurately without manually bleeding the line. Precise, controlled, dependable.
With a 144 SCFM flow capacity, this regulator is ideal for small to mid-range industrial applications that demand consistent performance.
Important Installation Note
A pressure gauge is required for proper monitoring and adjustment.
The regulator includes dual full-flow gauge ports for flexible installation.
