Norgren R72G-2GK-RMN Pressure Regulator - Relieving
Part Number: R72G-2GK-RMN
Quick Summary
Norgren R72G-2GK-RMN pressure regulator provides precise downstream pressure control for compressed air systems in manufacturing and automation. Engineers often contend with drift, dead-end pressure buildup, and unauthorized knob adjustments; this model’s push-to-lock knob and tamper-resistant features help address these challenges. The Excelon family offers CE conformity and robust duty across industrial environments, with relieving capability for safe depressurization and reliable setpoint stability. Designed for inline or modular installation, it delivers consistent control while reducing installation time and overall lifecycle costs for pneumatic systems.

Excelon design enables both in-line and modular installation, reducing dedicated space needs and simplifying retrofit projects. This translates to faster commissioning and lower installation costs on new lines and upgrades; ideal for control panels and pneumatic manifolds in manufacturing. The regulator uses a balanced valve for tight pressure control, minimizing fluctuations that affect actuators and tools, improving cycle consistency and accelerating throughput. With the relieving model, downstream pressure can be reduced safely when a system is dead-ended, protecting components and enabling safer maintenance windows. The push-to-lock adjusting knob, paired with tamper-resistant accessory options, prevents unauthorized setpoint changes and preserves process integrity in high-mix environments. Durable materials—zinc diecast body, acetal bonnet and knob, and nitrile elastomer seals—support long service life in dirty or damp factory floors while maintaining reliable performance across a wide temperature range. Its compact dimensions (Height 49 mm, Length 106 mm, Width 51 mm) and modest weight enable easy replacement and retrofit within existing footprints, with compatibility for inline use on G1/4 ports and Rc1/8 gauge ports to support measurement and tuning.

FAQs
The R72G-2GK-RMN supports both inline and modular installation, enabling flexible mounting on control panels or manifolds. This reduces footprint, simplifies retrofits, and accelerates commissioning in manufacturing lines. The G1/4 port size and Rc1/8 gauge port provide straightforward plumbing and measurement connections for rapid setup and ongoing tuning.
Key specifications include a maximum inlet pressure of 20 bar and an outlet pressure adjustment range of 0.3 to 10 bar (4 to 145 psi). The medium is compressed air, with a flow capacity of 33 dm3/s (70 scfm). These values support stable downstream pressure for pneumatic actuators and tooling while maintaining energy efficiency.
Yes, the R72G-2GK-RMN is a relieving regulator. This means it can reduce downstream pressure when the system becomes dead-ended, protecting downstream components from overpressure and enabling safer depressurization during maintenance or fault conditions. This feature improves safety and reduces the risk of component damage in stalled or blocked lines.
Key materials include a zinc pressure diecast body, an acetal bonnet, an acetal adjustment knob, and nitrile rubber elastomers, all chosen for toughness and chemical resistance. The operating temperature range is -34 to 65 C (-29 to 149 F). These choices support long service life in dirty, humid, or temperature-variant factory environments while preserving setpoint accuracy.
CAD models are available via the CAD download link, and full datasheets are provided in PDF format for specification verification. An installation guide is also accessible to aid wiring, mounting, and commissioning. Accessories include tamper-resistant knobby configurations and gauge options, enabling safer operation and easier on-site tuning.
