Norgren R84G-6AT-RMG Excelon Plus Pressure Regulator - 20 bar
Part Number: R84G-6AT-RMG
Quick Summary
Norgren R84G-6AT-RMG is a general purpose pressure regulator for compressed air systems. Engineers often struggle with fluctuating line pressures that degrade tool performance and increase cycle times. The Excelon Plus series supports CE-compliant installations and offers IP-rated configurations where required, paired with a compact die-cast aluminium body and a flush-mounted integrated gauge for quick verification. Designed for simple installation, the T-bar adjustment and 3/4\" PTF ports minimize assembly steps while delivering precise outlet settings from 0.3 to 10 bar. With a 20 bar maximum inlet and relieving operation, this regulator provides reliable, maintenance-friendly performance for automation lines, helping reduce energy waste and downtime.

FAQs
The R84G-6AT-RMG uses a 3/4" PTF port for supply lines and a 1/8" PTF gauge port, allowing straightforward integration with common pneumatic manifolds. Compatible mounting options include Excelon Plus Mounting Brackets, Quikclamp assemblies, and panel nut kits, which streamline retrofits and new builds without sacrificing accessibility or diagnostics.
The regulator delivers precise outlet pressure across 0.3 to 10 bar with relieving actuation, ensuring stable downstream pressure during load changes. The 20 bar maximum inlet protects downstream components and supports rapid stabilization after startup, improving tool repeatability and reducing air waste in automation cells.
The Excelon Plus family is designed for CE-compliant installations and offers configurations that align with common industrial safety practices. For safety-critical or SIL-related applications, verify the specific machine safety architecture and select configurations or accessories that meet your plant's SIL/ safety requirements, while leveraging the regulator's relieving operation for safer depressurization in line with standard procedures.
The flange-mounted gauge is flush with the bonnet for quick visual verification. After mounting, set the outlet pressure using the T-bar adjustment, reference the gauge port for real-time monitoring, and confirm readings against your process setpoint. For installations requiring panel integration, use the Excelon Plus Gauge KIT (840073-01KIT) to maintain visibility in cramped cabinets.
Choose elastomer seals compatible with your process fluids (nitrile rubber is standard for many compressed air systems). The diecast aluminium body provides robust durability, while regular inspection of the gauge port and adjustment mechanism helps maintain accuracy. For extended life, pair with compatible mounting and service kits such as the Elastomer Service Kit FRLB84-KIT and panel nuts that simplify field servicing.
