Norgren R72G-3GK-NFN Pressure Regulator - 0.3-4 bar
Part Number: R72G-3GK-NFN
Quick Summary
Excelon pressure regulator R72G-3GK-NFN delivers precise compressed air pressure control for compact automation systems. This device addresses space constraints and the risk of downstream over-pressure by delivering stable outlet pressure. CE-compliant by design, with rugged construction and available IP-rated variants in the Excelon range to withstand harsh environments. Using inline installation or modular mounting reduces panel footprint, while the tamper-resistant knob helps maintain setpoints and reduces unintended changes in busy production lines. In practice, you gain improved repeatability, easier maintenance, and predictable operating costs when integrating this regulator with standard G3/8 plumbing.

FAQs
Install the regulator with a G3/8 inlet connection and Rc1/8 gauge port for monitoring. Use inline or modular mounting as supported by the Excelon range to optimize space. Ensure the outlet is configured for 0.3-4 bar and verify the 20 bar maximum inlet pressure rating. The push to lock knob helps prevent setpoint drift after installation, and pairing with a compatible pipe adaptor (G3/8) simplifies plumbing.
Key specs include medium: compressed air; port size: G3/8; outlet pressure adjustment: 0.3–4 bar (4–58 psi); maximum inlet pressure: 20 bar; non-relieving regulation; gauge port Rc1/8; flow: 33 dm3/s (70 scfm). Material details include a zinc pressure die-cast body, acetal bonnet and knob, and nitrile elastomer seals.
Yes. Its 0.3–4 bar adjustable outlet and non-relieving design provide stable pressure to actuators, improving repeatability and response consistency in automated lines. The G3/8 size and inline/modular installation support a wide range of actuator configurations in compact panels.
The Excelon series is designed with industrial safety and European compliance in mind, featuring CE-compatible design and robust construction for demanding environments. For specific IP ratings or SIL configurations, consult the latest Excelon data sheets and the accompanying installation guides to ensure alignment with your site requirements.
Regular visual inspection for leaks and wear, and periodic verification of outlet pressure against the setpoint are recommended. The tamper-resistant knob helps maintain calibration between maintenance intervals. Use compatible fittings and maintain clean, dry compressed air to preserve seal life and ensure consistent regulation.
