Norgren R82R-3AT-RSG Reverse Flow Regulator - Gauge
Part Number: R82R-3AT-RSG
Quick Summary
The Norgren R82R-3AT-RSG reverse flow regulator provides precise pressure control for compressed air systems in automation and packaging lines. Designers often struggle with bulky regulators that consume panel space, add weight, and complicate maintenance in compact installations. Certifications commonly required for regulators in European and global markets include CE marking for safety compliance and IP ratings for enclosure protection; SIL ratings are relevant for safety-critical lines. This model’s compact form, flush-mounted gauge, and modular Excelon Plus design enable fast installation and predictable maintenance, while the 3/8" NPT port compatibility eases system integration. In turn, you gain reduced footprint, improved visibility, and lower total cost of ownership across your pneumatic network.

FAQs
Install the R82R-3AT-RSG using standard 3/8" PTF piping and ensure the 1/8" gauge port remains accessible for quick pressure checks. The flush-mounted gauge aids panel density and visibility, while the modular Excelon Plus design minimizes space consumption. Ensure clearance around the body for heat dissipation and use appropriate fittings to avoid leaks in tight panels.
The regulator provides an adjustable outlet range of 0.7 to 17 bar (10 to 247 psi) and a maximum inlet pressure of 20 bar. This supports stable downstream pressure control across typical automation circuits, while allowing safe venting in relief scenarios without requiring supplementary regulators.
Yes. Relieving means the regulator vents excess pressure to atmosphere when the downstream line exceeds the set pressure, helping prevent over-pressurization. This model is designed as a relieving regulator, which is advantageous for factory floors with dynamic loads and rapid cycle machines, ensuring consistent downstream pressure and protecting sensitive components.
The unit features a diecast aluminium body with a zinc-plated steel adjusting knob and nitrile rubber elastomers, supporting robust performance in typical manufacturing environments. It operates from -20 to 65 °C (-4 to 149 °F), making it suitable for a wide range of processes while maintaining seal integrity and mechanical stability.
The flush-mounted, integrated gauge reduces the need for separate diagnostic tools and panel removal during routine checks, shortening maintenance windows. Operators can quickly verify downstream pressure without disassembly, improving first-pass adjustments, accelerating commissioning, and reducing unscheduled downtime in high-uptime production lines.
