Norgren R72R-2GK-RFN Excelon regulator - Relieving
Part Number: R72R-2GK-RFN
Quick Summary
Norgren R72R-2GK-RFN Excelon regulator provides precise reverse-flow pressure control for compressed air systems in automated manufacturing. Designers often battle pressure drift and tamper-prone adjustments that degrade tool performance. Certification details such as CE, SIL, or IP ratings aren’t listed for this model, so verify compliance against your sector requirements. The Excelon platform supports inline or modular installation, offering quick, scalable integration across line upgrades. Coupled with a balanced valve design and a push-to-lock knob, it reduces maintenance time and helps ensure stable output pressure. This combination translates into lower downtime, improved process control, and predictable pneumatic performance.

FAQs
Install the R72R-2GK-RFN by connecting it to the G1/4 port on your pneumatic line. The Excelon regulator supports in-line or modular installation, enabling scalable upgrades across a machine or line. Use the push-to-lock adjusting knob for secure setpoints and consider adding the Rc1/8 gauge port if you need an external pressure gauge. Ensure system supply does not exceed 20 bar.
Target outlet pressure is adjustable from 0.3 to 4 bar, with a maximum inlet pressure of 20 bar. The regulator is a relieving type, so excess pressure is vented to maintain stable output. For best results, match your actuator requirements to the 0.3–4 bar range and monitor regularly to prevent drift in dynamic loads.
Yes. The Excelon platform on the R72R-2GK-RFN is designed for inline or modular installation, which simplifies integration into existing lines and future expansions. The G1/4 port standard and Rc1/8 gauge port offer flexible connections, while a balanced valve design reduces pressure fluctuations, improving tool consistency in automated assemblies across plants.
Certification data for this model are not listed in the provided data. You should verify regulatory compliance with your supplier or datasheet before deployment, particularly if CE, SIL, or IP ratings are required in your industry. The datasheet and installation guide referenced in downloads can confirm any standards applicability. Consult the manufacturer for the latest approvals.
Maintenance and set-up considerations drive ROI by reducing downtime and extending component life. Use the tamper-resistant knob to maintain stable setpoints and the balanced valve design to minimize drift under cycling. The optional Rc1/8 gauge port enables continuous monitoring; routine inspection of elastomers and fittings helps prevent leaks in high-demand pneumatic networks. In addition, use proper filtration and regular seat checks to sustain long-term performance.
