Norgren R82R-2GT-RSN Reverse Flow Regulator - 0.7-17 bar
Part Number: R82R-2GT-RSN
Quick Summary
Norgren R82R-2GT-RSN is a compact reverse flow regulator for compressed air systems in automation. Designers often wrestle with bulky, hard-to-adjust regulators that waste panel space and compromise response time. The Excelon Plus family delivers a relieving regulator with G1/4 ports and an adjustable 0.7–17 bar output, designed for precise, reliable control. Certification coverage such as CE marking and SIL safety considerations, plus IP enclosure compatibility when installed in harsh environments, should be verified against your system requirements. This combination supports space-saving installation, consistent pressure control, and easier maintenance, delivering value for manufacturers pursuing leaner pneumatic circuits and predictable performance.

Feature: Relieving regulator with adjustable outlet pressure. Business Impact: Prevents over-pressurization and improves system safety, reducing risk of component fatigue and shutdowns. Application: Ideal for cylinder circuits and valve banks where precise venting and controlled release are critical. The design minimizes pressure spikes during cycle changes, contributing to longer actuator life and steadier motion. Feature: G1/4 port size with Rc1/8 gauge port. Business Impact: Easier integration with standard manifolds and diagnostic tooling, lowering installation time and the need for adapters. Application: Fits common pneumatic subsystems in automation lines, from pick-and-place to assembly cells. Feature: T-bar adjustment. Business Impact: Quick, tactile pressure tuning with repeatable settings, reducing commissioning time and maintenance outages. Application: On-the-fly balancing of regulator performance during line changes or product variants. Feature: 20 bar maximum inlet pressure; 0.7–17 bar outlet range. Business Impact: Wide operating window supports multi-zone control and scalable line upgrades, improving process accuracy while preserving safety margins. Application: Process-critical machines that demand stable downstream pressure under fluctuating supply. Feature: Lightweight, compact geometry (0.25 kg; 145 mm height × 47 mm length × 56 mm width). Business Impact: Minimal panel footprint and reduced installation weight for modular systems and mobile machines. Application: Space-constrained panels and portable automation modules benefit from easier handling and faster retrofits. Feature: Diecast aluminium body, aluminium bonnet, nitrile elastomer seals. Business Impact: Robust construction ensures long life in demanding environments while resisting common pneumatic fluid contaminants. Application: Industrial environments with exposure to vibration, temperature swings, and routine maintenance cycles.

FAQs
The R82R-2GT-RSN uses standard G1/4 ports, allowing straightforward mounting on common manifolds and panels. For best results, align the flow direction with the regulator’s markings, use compatible seals (Nitrile elastomer), and verify that gauge ports (Rc1/8) are connected to appropriate monitoring lines to maintain accurate pressure readings during operation.
Key specs include a maximum inlet pressure of 20 bar and an adjustable outlet pressure range from 0.7 to 17 bar, with reliving operation. This setup helps prevent over-pressurization while delivering precise downstream pressure control for most pneumatic actuators in automation cells.
Yes, when paired with proper system design and calibration. The T-bar adjustment provides tactile, repeatable control, and the 0.7–17 bar outlet range supports tight regulation for cylinders and grippers. Its low weight and compact dimensions also simplify integration into space-constrained assemblies common in take-off lines and packaging equipment.
Certification details are not listed in the provided data. For compliance, confirm CE marking, SIL-safety considerations, and any IP enclosure requirements with the supplier literature and your internal standards. Always review the installation guide and datasheet to ensure your application meets the necessary regulatory and safety criteria.
The Excelon Plus regulator offers a compact, modular design with durable materials (diecast aluminium body, aluminium bonnet, nitrile seals) that resist wear in typical industrial environments. Benefits include reduced downtime during setup, predictable pressure regulation, and potential energy savings from stable downstream pressure, contributing to faster ROI in automated lines and high-mix production environments.
