Norgren R82R-2GK-RFN Excelon Plus Reverse Flow Regulator - Relieving
Part Number: R82R-2GK-RFN
Quick Summary
Norgren R82R-2GK-RFN Excelon Plus reverse flow regulator provides precise pressure control in pneumatic systems for compact automation equipment. Engineers often struggle with backflow, pressure spikes, and tamper-prone adjustments that disrupt line efficiency. In regulated environments, considerations such as SIL safety integrity, CE compliance, and IP-rated ruggedness are important for ensuring safe, reliable operation on harsh factory floors. This model offers a compact, lightweight form with a push to lock adjusting knob that resists accidental changes, while the reliving design delivers dependable venting when pressure relief is required. By combining robust materials with a modular system and standard G1/4 ports, it helps reduce installation time and maintenance while supporting consistent downstream performance across multiple lines.

FAQs
To install the R82R-2GK-RFN, mount the regulator with the G1/4 port orientation as shown in the datasheet, connect the inlet from the compressed air supply and route the outlet to the downstream line, and optionally attach the Rc1/8 gauge port for pressure monitoring. Use a stable panel mount and tighten fittings to minimize leaks. The push-to-lock knob helps prevent inadvertent setpoint changes during operation.
Key performance specs include a outlet pressure adjustment range of 0.3 to 4 bar, a maximum inlet pressure of 20 bar, flow capability of 33 dm3/s (70 scfm), and relieving operation. The porting includes G1/4 for inlet/outlet and Rc1/8 for the gauge port. Operating medium is compressed air, with a compact, lightweight die-cast aluminum body for industrial environments.
Yes. The model offers a tight, adjustable 0.3–4 bar range, a tamper-resistant knob for stable setpoints, and a compact form factor ideal for crowded automation panels. Its relieving design helps maintain accurate downstream pressures under load, while standard G1/4 connections simplify integration with actuators, pilots, and pressure sensors across automated lines.
Industrial regulators like the R82R-2GK-RFN are designed to meet general regulatory expectations for pneumatic components used in automation. Check the specific product documentation or datasheet for confirmation of CE marking, IP protection levels, or SIL-related suitability. If your project requires formal certification, verify with the supplier or distributor before deployment.
Maintenance is simplified by a tamper-resistant knob that reduces drift from accidental adjustments, a compact, durable housing, and modular design that supports quick replacements or upgrades. ROI benefits come from extended service life, reduced downtime due to backflow issues, and faster commissioning thanks to standardized G1/4 connections and straightforward installation.
