Norgren R82R-2AT-RSN Reverse Flow Regulator - Excelon 0.7-17
Part Number: R82R-2AT-RSN
Quick Summary
Norgren R82R-2AT-RSN Excelon Plus reverse flow regulator controls outlet pressure for compressed air systems. It helps prevent backflow and pressure spikes that disrupt automation lines. In this class, typical industry standards include CE marking and robust housings, with reliability supported by the diecast aluminium body, aluminium bonnet, and nitrile elastomer seals; verify exact approvals in the datasheet. This compact, modular regulator reduces footprint and simplifies installation, while offering a precise T-bar adjustment for quick setup in 1/4" NPT pneumatic circuits and 1/8" gauge port configurations. For OEMs and service teams, it delivers consistent performance with easy maintenance and scalable integration into existing networks.

Feature → Business Impact → Application: The Excelon Plus R82R-2AT-RSN includes a reverse flow design that prevents back pressure from destabilizing upstream components, reducing unplanned downtime in pick-and-place and packaging lines. This translates to improved line availability and lower maintenance costs in high-cycle automation. Feature → Business Impact → Application: Outlet pressure is adjustable from 0.7 to 17 bar via a T-bar knob, enabling precise actuator control and repeatable performance across multiple machines, which minimizes set-up time and improves process consistency in pneumatic feeders and clamps.

FAQs
The R82R-2AT-RSN is designed for 1/4 inch NPT ports; connect the port to standard pneumatic fittings with appropriate sealants or thread tape. Align the gauge port with the accessory line as recommended, then tighten fittings to manufacturer torque specs. Use the T-bar adjustment to set initial outlet pressure, then validate with a calibrated gauge to ensure stable performance at load.
Outlet pressure is adjustable from 0.7 to 17 bar using the T-bar knob. Start with the regulator disconnected, set a nominal baseline on the gauge, and then apply system load to verify regulation accuracy. Fine-tune under typical operating conditions to achieve repeatable actuator response and avoid overshoot during startup.
Yes, the unit supports a flow of up to 33 dm3/s (70 scfm) and a maximum inlet pressure of 20 bar, making it suitable for many medium-demand pneumatic circuits. For larger actuators or higher throughput, consider staged regulation or parallel regulators to maintain stable outlet pressure at peak demand.
The regulator uses a diecast aluminium body with an aluminium bonnet, zinc-plated steel adjusting knob, and nitrile rubber elastomers. This combination provides durability, corrosion resistance, and temperature tolerance from -20 to 65 °C, helping maintain performance in factory floors and exposure-prone installations.
