IMI Norgren R72G-2AK-NFN Pressure Regulator - 0.3-4 bar
Part Number: R72G-2AK-NFN
Quick Summary
Pressure regulator solutions stabilize compressed air for automated systems, delivering steady pressure to pneumatic actuators. Many plants struggle with pressure spikes and gauge drift that degrade performance and waste energy. In many projects, CE marking and rugged construction are important, and for safety-critical lines, SIL-rated components are a consideration. Excelon design enables in-line or modular installation, with a balanced valve that reduces pressure fluctuation and increases control accuracy. Push-to-lock adjustment and tamper-resistant features minimize field changes, supporting predictable maintenance intervals and lower downtime. For procurement teams, this combination translates to reliable performance, reduced energy consumption, and easier compliance across European manufacturing environments.

FAQs
The regulator supports inline installation as well as modular mounting. Recommended accessories include the Neck Mounting Bracket 74316-50 and Quikclamp variants 4214-51/52, enabling compact, secure setups in panel or wall-mounted configurations without sacrificing serviceability.
It handles up to 20 bar inlet pressure with an adjustable outlet range of 0.3 to 4 bar. The unit uses a 1/4" PTF port for supply and a 1/8" PTF gauge port for monitoring, supporting precise pressure control and straightforward calibration.
Yes. The Excelon design is explicitly intended for inline or modular installation, offering stable pressure control for continuous packaging and automation workflows. The balanced valve helps maintain setpoints during load changes, improving line efficiency and product consistency.
Maintenance benefits come from the tamper-resistant knob with push-to-lock adjustment and robust materials (acetal, nitrile elastomers, zinc die-cast body). Regular checks should verify seal integrity, knob security, and flow performance, minimizing drift and unexpected recalibration during production runs.
Stable outlet pressure reduces cycle variance, lowers air leaks, and minimizes energy waste. The non-relieving design helps conserve compressed air, while easy installation and tamper-resistant features reduce downtime and adjustment errors, delivering measurable improvements in throughput and operating costs over the life of the line.
