Norgren R72G-2GK-NFN Excelon Pressure Regulator - 0.3–4 bar
Part Number: R72G-2GK-NFN
Quick Summary
Norgren R72G-2GK-NFN is a general purpose pressure regulator designed for precise control in compressed air systems. Engineers often contend with pressure fluctuations that degrade tool performance and cycle consistency. The Excelon family supports CE marking for European compliance and is designed for reliable operation in rugged factory environments, with options that accommodate IP-rated housings and SIL configurations where safety-critical. This model offers inline or modular installation and a tamper-resistant push-to-lock knob, reducing drift, maintenance downtime, and the need for retraining staff. In practice, its compatibility with Excelon 72 accessories helps streamline retrofits and upgrades.

Inline or modular installation supports space-constrained layouts, reducing installation time and enabling easy retrofits in existing lines. This translates to lower installation labor costs and faster time-to-production for new or modified cells. The balanced valve design delivers stable outlet pressure, improving tool performance, cycle accuracy, and downstream process reliability in automated assemblies. The push-to-lock adjusting knob with tamper-resistant accessory prevents unauthorized changes, reducing drift and maintenance calls in shared manufacturing environments. A non-relieving design enhances safety in exhaust paths, supporting cleaner, safer work environments and simpler compliance checks. Gauge port Rc1/8 enables straightforward system verification and commissioning during start-up and service windows. Robust materials and a 20 bar inlet tolerance deliver durable, long-term operation in high-demand plants.

FAQs
The R72G-2GK-NFN supports both inline and modular installation on Excelon 72 manifolds and compatible frames. For retrofit projects, use the 4216-52 porting block or the 4214-51 Quikclamp family to secure the regulator and align with G1/4 piping. This minimizes rework and ensures a clean, scalable upgrade path for existing pneumatic circuits.
Primary specs to verify are: outlet adjustment range 0.3–4 bar, maximum inlet pressure 20 bar, non-relieving exhaust, port size G1/4, gauge port Rc1/8, and flow capacity 33 dm3/s. These values determine compatibility with downstream actuators, valves, and your existing piping manifold, ensuring stable pressure under peak demand.
Yes, the R72G-2GK-NFN suits high-cycle automotive assemblies where consistent pneumatic pressure improves tool life and repeatability. Its inline/modular installation, tamper-resistant knob, and robust materials support demanding environments, while the broad 0.3–4 bar output range accommodates multiple tooling configurations without frequent readjustment.
The Excelon line typically aligns with CE marking for European compliance and is designed for rugged industrial use; IP ratings depend on housing configuration, and SIL-capable configurations are available for safety-critical lines. Always confirm the exact certification set on the datasheet or with your distributor for your region and application.
The tamper-resistant knob reduces drift and need for mid-shift recalibration, lowering maintenance calls. Inline or modular installation shortens installation time and simplifies retrofits, accelerating time-to-availability. With durable materials and a wide inlet range, you get long service life and fewer part replacements, delivering a favorable total cost of ownership in high-demand production environments.
