Norgren R82G-2GT-RSN Pressure Regulator - Relieving
Part Number: R82G-2GT-RSN
Quick Summary
R82G-2GT-RSN is a general-purpose pressure regulator for compressed air systems in automation. Many engineers struggle with bulky regulators that add weight and consume valuable panel space while complicating field tuning. Engineers typically seek CE compliance, IP protection, and SIL considerations to ensure safety and long-term reliability. As part of the Excelon Plus family, this regulator offers a compact, modular design that lowers downtime and total cost of ownership. With G1/4 ports, T-bar adjustment, -20 to 65 °C operation, and a 20 bar inlet rating, it delivers precise setpoints up to 17 bar in demanding environments.

Feature: Compact, lightweight construction backed by a diecast aluminium body and aluminium bonnet reduces installation footprint and weight, enabling easier panel mounting and faster retrofits. Business Impact: Lower installation costs, reduced shipping weight, and simplified service in tight spaces. Application: Control panels and compact automation lines where space is at a premium. Feature: Precise regulation via T-bar adjustment and a broad outlet range from 0.7 to 17 bar with a 20 bar maximum inlet. Business Impact: Fast, repeatable setpoints and stable pressure delivery, minimizing part wear and improving actuator performance. Application: Pneumatic circuits requiring tight pressure control for consistent cylinder speed and force. Feature: Relieving regulator design delivers venting to atmosphere when set pressure is reached, enhancing safety and overpressure protection. Business Impact: Improved system safety, reduced risk of accidental over-pressurization, and easier compliance with safety workflows. Application: Safety-critical pneumatic lines and test benches. Feature: Adequate flow capacity of 33 dm3/s (70 scfm) supports multiple actuators or higher demand zones without pressure drop. Business Impact: Higher throughput and fewer downstream bottlenecks, reducing cycle times. Application: Medium-scale automation zones with several cylinders operating in parallel. Feature: Robust material selection – zinc-plated steel knob, diecast aluminium body, aluminium bonnet, and nitrile elastomer seals – provides durability in manufacturing environments. Business Impact: Longer service life, lower maintenance frequency, and predictable performance across shifts. Application: Wide-temperature factory floors and washdown-adjacent areas (within rated operating range). Feature: Excelon Plus compatibility and modular design enable straightforward integration with Norgren’s accessory ecosystem and service tools. Business Impact: Faster commissioning, easier field upgrades, and lower total cost of ownership. Application: Existing Excelon Plus installations and new lines requiring scalable pneumatic regulation.

FAQs
The regulator uses a G1/4 port for main flow and a Rc1/8 gauge port for monitoring. Install with standard pneumatic fittings, hand-tighten then torque to spec per the installation guide, and use the T-bar to set your desired outlet pressure within 0.7–17 bar. Ensure the inlet supply is within the 20 bar maximum and that the regulator is mounted in a vibration-free location.
Outlet pressure is adjustable from 0.7 to 17 bar (10 to 247 psi). The regulator supports a maximum inlet pressure of 20 bar, with a -20 to 65 °C operating range for reliable performance in standard industrial environments.
Yes. The device is a relieving regulator, which vents to atmosphere when set pressure is reached, helping to prevent overpressure and enabling safer operation of pneumatic circuits in automated lines.
Key specs include 33 dm3/s (70 scfm) flow capacity, G1/4 port, Rc1/8 gauge port, -20 to 65 °C operating range, 20 bar max inlet, and a 0.7–17 bar regulation window. These ensure stable pressure delivery for mid‑volume pneumatic systems.
Durable materials (diecast aluminium body, aluminium bonnet, nitrile elastomer seals, zinc-plated adjusting knob) support long service life in busy plants. Regular inspection of seals and setpoint verification using the T-bar adjustment helps maintain precision and reduces unexpected downtime; reference the datasheet and installation guide for intervals and procedures.
