Overview
The Numatics R50R-06 is a relieving-type pneumatic regulator from the proven 50-series platform, engineered for high-flow industrial automation and motion control. This unit delivers stable, adjustable pressure from 0–125 PSIG (0–8.6 bar) output with a maximum inlet pressure of 300 PSIG (20.7 bar). The 3/4″ NPTF threaded ports and integral pressure gauge make it a drop-in solution for compressed air circuits, FRL (filter-regulator-lubricator) assemblies, and pneumatic control systems.
Key Features
- High-flow capacity: 395 SCFM at +80 PSIG, 385 SCFM at +60 PSIG for demanding applications
- Relieving design: Maintains outlet pressure by venting excess air, ideal for load-holding and dynamic control
- Integrated gauge: Built-in 0–160 PSIG display for quick pressure verification without external instrumentation
- Diaphragm-operated: Smooth, responsive pressure response with minimal hysteresis
- T-handle adjustment: Ergonomic knob for fast, intuitive pressure setting in the field
- NPTF threads: Standard industrial connection compatible with most pneumatic piping and manifolds
