Norgren R82R-2AK-RFN Excelon Plus Regulator - Relieving
Part Number: R82R-2AK-RFN
Quick Summary
R82R-2AK-RFN Excelon Plus reverse flow regulator provides precise outlet pressure control for compressed air systems in automation. Engineers often contend with tamper-prone adjustments and inconsistent flow in compact installations, which can drive downtime and waste energy. Certifications such as CE, SIL or IP ratings are not specified in the data; verify with manufacturer documentation before procurement. The unit uses a push-to-lock adjusting knob with built-in tamper resistance and a lightweight diecast aluminium body for a small, robust footprint. With 1/4" NPT ports and a 1/8" gauge port, it simplifies field installation and troubleshooting. Rated to 20 bar max inlet and 0.3–4 bar adjustable outlet, it delivers reliable regulation with minimal parts count, supporting maintenance efficiency and reduced lifecycle cost.

Excelon Plus design offers a compact, lightweight regulator that reduces panel footprint and overall system mass. This enables space-constrained installations and easier service access, improving machine ergonomics and reducing setup time. Ideal for OEM lines and retrofits in automation cells where space is at a premium. Push-to-lock adjusting knob with tamper resistance prevents unintended changes during operation, delivering stable regulation and fewer drift events. This translates to predictable actuator performance and lower maintenance costs in high-cycle environments such as packaging and electronics assembly. The relieving regulator protects downstream equipment by venting excess pressure and preventing backflow, enhancing safety and reliability across pneumatic circuits serving cylinders and valves. Installation remains straightforward with 1/4" NPT ports and a 1/8" gauge port, supporting quick diagnostics. The unit tolerates up to 20 bar inlet pressure and offers a controllable 0.3–4 bar outlet range, enabling flexible tuning for diverse loads and processes. Built for durability, the diecast aluminium body, POM bonnet, acetal knob, and nitrile elastomer seals withstand factory vibration and chemical exposure while delivering long service life with minimal maintenance.

FAQs
The R82R-2AK-RFN uses standard 1/4" NPT ports with a 1/8" gauge port for diagnostics. For best results, mount the regulator in a clean, vibration-free area within the compressed air line, ensure compatible fittings are used, and verify the gauge port connections with appropriate test adapters to monitor outlet pressure without disturbing the main line once installed.
This model provides an outlet pressure adjustment from 0.3 to 4 bar (4 to 58 psi) and is rated for a maximum inlet pressure of 20 bar. This range supports precise actuation of downstream valves and cylinders while maintaining safety margins in typical automation applications.
Yes, the R82R-2AK-RFN is a relieving regulator. The relief path helps protect downstream components from overpressure by venting excess pressure when the setpoint is exceeded, enhancing system safety and preventing unintended actuator cycling or damage in dynamic loads.
The regulator combines a diecast aluminium body with a POM bonnet, an acetal adjusting knob, and nitrile rubber elastomer seals. This blend delivers structural durability, resistance to vibration, and reliable sealing in standard factory conditions, contributing to a longer service life with reduced maintenance
The push-to-lock knob includes a tamper-resistant design that minimizes unintentional pressure changes during operation. This reduces drift, rework, and downtime, leading to more consistent performance, lower idle time, and a faster return on investment for automation lines and retrofit projects.
