Norgren R82G-2AK-RFN Excelon Plus Regulator - Relieving
Part Number: R82G-2AK-RFN
Quick Summary
Norgren R82G-2AK-RFN Excelon Plus regulator is a precision pressure regulator for compressed air systems in automation and manufacturing. Engineers often struggle with drift, overshoot, and tamper-prone adjustments that disrupt line uptime. This model features a push-to-lock adjusting knob with built-in tamper resistance, helping maintain set pressures in harsh environments. While many regulators offer basic control, the Excelon Plus design emphasizes a compact, lightweight footprint and a flexible modular system that simplifies installation and future upgrades. When evaluating regulators, verify safety and environmental compliance (CE marking) and consider environmental protection needs (IP ratings). The result is reliable, scalable regulation that reduces downtime and total cost of ownership for critical pneumatic lines.

Compact and lightweight construction reduces installation footprint and simplifies routing in tight panel spaces, delivering measurable space and labor savings on new builds and retrofits. This translates to faster machine commissioning, easier service access, and lower total installed cost. The Excelon Plus family’s flexible modular architecture enables rapid configuration changes and straightforward upgrades to future regulators without replacing plumbing or wiring, cutting downtime during line changes and reducing spare parts inventory. The push-to-lock adjusting knob adds tamper resistance, minimizing inadvertent pressure drift from operator interaction and extending set-point stability in busy manufacturing environments. Relieving regulator action provides predictable venting and stable downstream pressure, improving cycle consistency and tool performance in automation cells. Durable die-cast aluminium bodies with POM bonnet and nitrile elastomer seals offer robust wear resistance and chemical compatibility, lowering maintenance and replacement costs over the regulator’s life. The integrated 1/4" NPT port with a 1/8" gauge port supports standard pneumatic plumbing, while compact dimensions (115 mm x 56 mm x 47 mm) and a light 0.23 kg weight facilitate quick mounting and minimal panel intrusion across multiple workstations.

FAQs
The R82G-2AK-RFN installs via standard 1/4" NPT port connections with a dedicated 1/8" gauge port for pressure monitoring. Use correct thread sealant and torque per Norgren guidelines, mount with adequate clearance for the knob, and connect the gauge line to the 1/8" port to monitor outlet pressure. Ensure downstream components are rated for 0.3–4 bar and that the maximum inlet does not exceed 20 bar.
Key performance specs include an outlet pressure adjustment range of 0.3 to 4 bar (4 to 58 psi) with a maximum inlet pressure of 20 bar. The regulator processes up to 33 dm3/sec (70 scfm) of flow and uses a 1/4" NPT port complemented by a 1/8" gauge port for monitoring. These figures support stable regulation across typical automation workloads.
The R82G-2AK-RFN is designed for industrial automation settings and operates from -20 to 65 °C (-4 to 149 °F). Its diecast aluminium body, POM bonnet, and nitrile elastomer seals provide durability and chemical resistance. For outdoor or particularly harsh environments, confirm IP protection and enclosure ratings with your supplier and consider additional protective measures.
When selecting regulators, verify CE safety conformity and applicable IP protection requirements for your environment. If your safety or process needs include functional safety or SIL considerations, check with the supplier whether the specific R82G-2AK-RFN variant supports SIL-rated configurations or compatible safety-certified options within the Excelon Plus family.
The tamper-resistant push-to-lock knob helps prevent unintended pressure changes, reducing drift and rework in high-traffic production lines. Combined with a compact, modular design and reliable diecast aluminium construction, you can expect lower maintenance labor, faster swaps or upgrades, and improved line uptime—yielding a favorable return on investment through more consistent pneumatic performance.
