Norgren R82R-3GK-RFG Reverse Flow Regulator - Relieving
Part Number: R82R-3GK-RFG
Quick Summary
Norgren R82R-3GK-RFG reverse flow regulator controls pressure in compressed air systems for precise pneumatic tooling and automation. Engineers often face backflow, fluctuating outlet pressures, and tamper-prone adjustment knobs that disrupt cycle consistency. This Excelon Plus model supports robust performance in demanding environments, with integrated gauge visibility and a push-to-lock knob that resists unauthorized changes. By combining a compact diecast body with a light 0.23 kg weight and a G3/8 port, it fits tight machine layouts while preserving full flow. The unit is designed for -20 to 65 °C operation and supports reliable relieving regulation, enabling safer startup and reduced tool wear. CE-aware design and standardized dimensions help streamline compliance and installation across multi-site plants.

FAQs
For tight panel spaces, rely on the compact 115 mm height, 47 mm length, and 56 mm width with a lightweight 0.23 kg body. Use the G3/8 main port and Rc1/8 gauge port to simplify plumbing, and install the flush-mounted gauge for quick pressure checks during setup and maintenance.
Key specs include a 0.3–4 bar outlet range, 20 bar maximum inlet pressure, and a flow of 31 dm3/sec. The unit operates from -20 to 65 °C and uses a relieving design to protect tooling. Together these ensure stable downstream pressure, reduced cycle variation, and safer startup in automation cells.
Yes, with a 31 dm3/sec flow capacity and a G3/8 port, the R82R-3GK-RFG supports common high-demand tooling setups. The relieving function helps protect sensitive actuators, while the integrated gauge and tamper-resistant knob aid in consistent, compliant operation across multiple workstations.
Verify CE compliance for European installations and check IP ratings and SIL considerations within your system design. Certifications can vary by configuration and region; consult the datasheet and installation guide to confirm exact regulatory alignments for your plant.
The integrated gauge reduces maintenance time by enabling rapid verification, while the tamper-resistant knob minimizes drift and unauthorized adjustments. The compact design lowers panel rework, and stable pressure improves tooling life, resulting in lower maintenance costs and potential energy efficiency gains over the system lifecycle.
