IMI Norgren R82G-3AK-RFG Regulator - Relieving
Part Number: R82G-3AK-RFG
Quick Summary
R82G-3AK-RFG Excelon Plus regulator is a precision pressure control solution for compressed air systems. It helps maintain stable downstream pressure, reducing drift and variability in automated circuits. In crowded panels, a compact, integrated gauge and tamper-resistant knob minimize adjustments and inadvertent changes. This family aligns with CE-type safety considerations and widely adopted industry standards, with variants designed for robust operation in industrial environments. For procurement and maintenance, the Excelon Plus delivers a modular, lightweight solution that simplifies installation, reduces space needs, and supports consistent performance across multiple lines and applications.

Feature → Business Impact → Application: The regulator features a flush-mounted integrated gauge, which enables quick, accurate monitoring without protruding hardware, reducing setup time and potential panel interference in tight enclosures; application in high-density automation lines benefits from faster commissioning and easier fault tracing. Feature → Business Impact → Application: A knob-adjust mechanism with push-to-lock and tamper-resistant design minimizes unauthorized changes in critical processes, improving process stability and compliance in regulated environments. Feature → Business Impact → Application: Diecast aluminium body and lightweight construction lower weight and integral footprint, enabling simpler mounting on compact manifolds and reducing overall system weight in mobile or OEM equipment. Feature → Business Impact → Application: The 3/8" PTF inlet and 1/8" gauge port support standard pneumatic fittings and diagnostic access, ensuring broad compatibility with existing plant air networks and easy integration with pre-existing sensing/monitoring. Feature → Business Impact → Application: The relieving (relief-type) design provides controlled depressurization to prevent downstream overshoot, improving energy efficiency and protecting downstream components in packaging lines and assembly cells. Feature → Business Impact → Application: 0.3–4 bar outlet range and 20 bar max inlet pressure offer precise regulation across typical industrial cycles, enabling tight control of actuators while maintaining compressor/load efficiency. Materials such as acetal knob, POM bonnet, nitrile elastomers and a nickel-free choice provide chemical resistance and long life in oily or humid environments, reducing maintenance costs and downtime.

FAQs
Plan for a compact panel layout using the 3/8" PTF inlet and 1/8" gauge port to enable straightforward piping and diagnostics. Ensure supply air is clean and dry to protect nitrile elastomer seals, use the flush-mounted gauge for quick readings, and mount the unit in a location with access to the adjustment knob for service. The regulator supports up to 20 bar inlet and 0.3–4 bar outlet; verify correct orientation and secure mounting to avoid vibration.
Certification details for North American and European markets typically align with CE-type safety expectations for pneumatic regulators. Verify specific compliance in your region by consulting the datasheet and installation guide, and confirm any regional endorsements with your supplier. Relevant documents, including the datasheet and installation guide, are available in the downloads section to support certification audits.
The R82G-3AK-RFG supports a maximum inlet pressure of 20 bar. The outlet pressure is adjustable from 0.3 to 4 bar (4 to 58 psi), providing precise, stable regulation for a wide range of pneumatic actuators and downstream devices in automated lines.
Key construction includes a diecast aluminium body, a POM bonnet, an acetal adjusting knob, and nitrile elastomers for seals, all chosen for rigidity, chemical resistance, and long life in humid or oily industrial environments. The flush-mounted gauge and tamper-resistant knob further contribute to reliability in harsh factory settings and minimize unintended adjustments.
