Norgren R82R-2GK-RFG Reverse Flow Regulator - Relieving
Part Number: R82R-2GK-RFG
Quick Summary
Norgren R82R-2GK-RFG reverse flow regulator is designed to precisely control compressed air pressure in automation lines. In tight spaces and under fluctuating loads, regulators can drift, causing tool downtime and waste. Common certifications to verify include CE marking for safety, SIL reliability considerations, and IP ratings for environmental protection; consult the datasheet for details. The Excelon Plus family delivers a compact, modular solution featuring a flush-mounted integrated gauge, a push-to-lock adjusting knob, and reverse flow protection, all in a lightweight diecast body. This combination supports faster, more repeatable set-ups and reduced maintenance, while ensuring reliable performance across a range of industrial applications such as stamping, assembly, and automotive tooling.

FAQs
Begin by confirming the G1/4 port and Rc1/8 gauge port compatibility with your manifold. Mount the regulator in the intended orientation, ensure the flush-mounted gauge is accessible, and tighten connections to the recommended torque. Use the push-to-lock knob to secure adjustments and verify there are no leaks at the inlet or outlet. The compact diecast body helps fit into tight panels while maintaining proper clearance for the gauge.
The regulator provides an outlet pressure range of 0.3 to 4 bar (4 to 58 psi) with a maximum inlet pressure of 20 bar, and a flow specification of 33 dm3/s (70 scfm). This supports stable downstream pressure across variable loads, making it suitable for tooling actuation and clamping in automation cells that require repeatable pressure profiles.
Yes, thanks to the Excelon Plus design’s compact, lightweight construction (0.23 kg) and modular system, it fits into fast-cycle applications where space is at a premium. The integrated gauge plus tamper-resistant knob helps maintain setpoints in busy environments, while the reliving feature ensures quick response and reduces load-induced pressure fluctuations in rapid actuation sequences.
To ensure regulatory alignment, verify the product datasheet and installation guide for CE safety markings, reliability considerations (such as SIL-related expectations in relevant contexts), and any IP enclosure ratings applicable to your environment. Always cross-check the supplier’s documentation for up-to-date certification details before procurement.
The regulator’s integrated gauge and push-to-lock knob reduce maintenance steps by enabling quick verification and secure adjustments without tools. Its durable diecast aluminium body and Nitrile elastomer seals support long service life in demanding settings, lowering downtime and replacement costs. The modular Excelon Plus system also simplifies spares management and potential upgrades across multiple lines, improving overall ROI.
