Norgren R84G-6AT-RFN Pressure Regulator - Excelon Plus
Part Number: R84G-6AT-RFN
Quick Summary
Norgren R84G-6AT-RFN pressure regulator is designed to deliver stable compressed air pressure for actuating automation equipment across manufacturing lines. Fluctuating line pressure and pressure spikes often cause inconsistent cycle times and premature wear, making precise control essential. This Excelon Plus model is a relieving regulator built to perform in challenging environments, with a T-bar adjustment for fine setting and a compact, lightweight form. With CE marking for European compliance and ISO 9001 quality manufacturing practices, it is designed for durable, long service life in standard plant atmospheres. The 3/4 in PTF port and optional 1/8 in gauge port simplify integration into existing manifolds, while the modular mounting and available service kits help minimize downtime and total cost of ownership.

Compact, lightweight design reduces panel footprint and simplifies installation, delivering a clear business impact of faster project timelines and easier retrofits. The Excelon Plus modular system enables flexible configurations, meaning you can swap or add components without replacing the entire regulator, which translates to lower lifecycle costs and quicker adaptation to changing production needs in automated lines. The T-bar adjustment provides precise outlet pressure control (0.3–4 bar), reducing cycle variability and improving tool actuation accuracy in processes such as clamping and forming. The relieving regulator topology enhances safety by venting excess pressure automatically, mitigating downstream shocks and leaks in high-demand pneumatic circuits. Availability of 3/4 in PTF port with a 1/8 in gauge port supports straightforward plumbing and monitoring, while compatible mounting brackets and QuickClamp solutions speed up installation in control panels. Durability is reinforced by a diecast aluminium body, nitrile elastomer seals, and a zinc-plated steel adjusting knob, ensuring reliable performance in typical plant temperatures (−20 to 65 °C) and environments.

FAQs
The R84G-6AT-RFN is compatible with Excelon Plus mounting brackets and QuikClamp assemblies. These options reduce panel space, simplify alignment, and speed up installation, particularly in retrofit projects or multi-point manifolds. Accessory kits like 840024-50KIT and 840014-51KIT are commonly used to secure the regulator and integrate with existing frames, minimizing downtime during commissioning.
Key specs include a 3/4 in PTF inlet, a gauge port of 1/8 in PTF, a regulated outlet range of 0.3–4 bar, and a maximum inlet pressure of 20 bar. The reliving design helps prevent pressure overshoot, while the T-bar adjustment enables precise setpoint tuning. With a flow of about 125 dm3/sec (265 scfm), the regulator supports moderate tooling and actuator demands without sacrificing accuracy.
Yes. The Excelon Plus R84G-6AT-RFN is intended for general purpose compressed air regulation in automation environments. Its relieving function and adjustable output support stable actuator actuation, consistent cycle times, and safer operation in tooling lines. For best results, pair it with compatible gauge adapters and mounting kits to ensure robust, vibration-tolerant installation.
The regulator is positioned for European markets with CE marking and is produced to high-quality manufacturing standards. For system-level safety requirements, customers often verify ISO 9001-quality processes in the manufacturer and consider site-specific regulatory needs. Depending on the environment, some installations may require additional protection or IP-rated housings and SIL-level approvals at the system level.
Maintenance and lifecycle support include the Excelon Plus elastomer service kit FRLB84-KIT and compatible gauge adaptor kits such as 840100-01KIT. Regular replacement of elastomer seals and periodic calibration checks help sustain performance. For quick field service, use the provided installation guides and CAD resources to replace components with minimal disassembly and downtime.
