Norgren R84G-3AT-RFN Pressure Regulator - Relieving
Part Number: R84G-3AT-RFN
Quick Summary
Norgren R84G-3AT-RFN pressure regulator is designed to stabilize compressed air pressure for automation systems. In real-world panels, fluctuating supply pressure can cause erratic actuator response and increased wear; this model targets that pain by delivering consistent output across load variations. It aligns with CE conformity, RoHS compliance, and ISO 9001-based manufacturing quality controls, ensuring safe operation and reliable supply chain integration. Designed for panel-mounted installations in compressed-air systems, it supports flexible 3/8 in PTF piping and quick T-bar adjustment, offering business value by reducing downtime and maintenance. This combination delivers consistent pressure control across variable loads, improving tool accuracy and extending component life in automation lines.

Excelon Plus modular design enables flexible mounting and streamlined panel integration, reducing installation time and enabling scalable pneumatic control across multiple stations. The tight 0.3–4 bar output range delivers precise regulation, minimizing actuator overshoot and energy waste while improving repeatability in tooling cycles. Relieving operation ensures safe venting during shutdown sequences, lowering the risk of pressure spikes that can damage sensitive components. A 20 bar maximum inlet supports common plant air supplies, simplifying retrofits and new-build deployments without sacrificing performance. The 3/8" PTF port and 1/8" PTF gauge port provide straightforward piping and real-time monitoring, while T-bar adjustment offers intuitive, workshop-friendly tuning. With 0.79 kg weight and compact dimensions, the regulator fits narrow panels and tight enclosures, reducing cabinet footprint. The Excelon Plus materials—diecast aluminium body and zinc-plated steel knob—balance durability with lightweight handling, supporting long service intervals and predictable maintenance planning. Overall, the R84G-3AT-RFN pairs a robust mechanical package with modular accessories, enabling rapid installation and case-by-case optimization in automated production lines.

FAQs
The R84G-3AT-RFN uses 3/8" PTF inlet/outlet connections with a 1/8" PTF gauge port, simplifying integration with standard compressed air lines. It is designed for panel mounting in automation environments, and compatible mounting brackets from the Excelon Plus range support quick, secure installs in control panels and machine frames.
The regulator provides an adjustable outlet pressure range of 0.3 to 4 bar (4 to 58 psi). It tolerates a maximum inlet pressure of 20 bar, allowing reliable operation in typical plant air systems and reducing the risk of over-pressurization within downstream components.
Yes. The Excelon Plus line is designed for panel-mounted installations, and compatible mounting accessories such as the Excelon Plus General Mounting Bracket and Quikclamp kits help secure the regulator in tight control cabinets. This promotes clean wiring, reduces vibration concerns, and simplifies future servicing or replacements.
This regulator aligns with common industry expectations for safety and quality, including CE conformity for European safety compliance, RoHS for restricted substances, and ISO 9001-based manufacturing controls. These certifications matter because they assure regulators and procurement teams of consistent performance, safer operation, and a reliable supply chain across plant environments.
Maintenance is supported by the Excelon Plus elastomer service kit FRLB84-KIT for elastomer seals and periodic diaphragm checks, helping extend service life and maintain accuracy. The unit’s lightweight build and modular design simplify on-site inspections, while availability of compatible mounting brackets reduces downtime during retrofit or replacement, delivering measurable uptime improvements and cost savings over time.
