Norgren R84G-3AT-RSG Pressure Regulator - Relieving
Part Number: R84G-3AT-RSG
Quick Summary
Norgren R84G-3AT-RSG pressure regulator stabilizes compressed air for automation systems. It addresses fluctuating pressures that cause actuator stalling and wear by delivering precise setpoints quickly. In the Excelon Plus family, engineers often rely on CE-compliant designs with SIL-ready configurations and robust IP-rated options to meet safety and reliability requirements. Built for fast integration with 3/8 in PTF ports and a flush-mounted integrated gauge, it helps reduce installation time and lifecycle costs while delivering consistent performance in compact form.

Excelon Plus R84/B84 Elastomer Service Kit
The integrated gauge and T-bar adjustment provide immediate visibility and precise setpoints, reducing trial fittings and calibration time, which speeds up commissioning and minimizes downtime in automated lines. By supporting a maximum inlet pressure of 20 bar and an adjustable outlet range of 0.7 to 17 bar, the regulator delivers reliable regulation across typical industrial air systems, improving process stability and reducing energy waste. The diecast aluminium body with a 3/8" PTF feed and 1/8" PTF gauge port enables compact panel mounting, saving valuable enclosure space while maintaining durability in harsh plant environments. A relieving design protects downstream equipment from overpressure events, enhancing safety and compliance in regulated facilities. Its modular Excelon Plus ecosystem compatibility, including mounting brackets and integrated gauge options, simplifies retrofits and future expansions. Serviceability is supported by elastomer-based components and a dedicated elastomer service kit, helping minimize maintenance downtime and lifecycle costs.

FAQs
Yes. The unit uses a 3/8" PTF supply port and a 1/8" PTF gauge port, enabling straightforward installation on common pneumatic lines. For mounting, options within the Excelon Plus family include 840024-50KIT (General Mounting Bracket), 840068-51KIT (Neck Mounting Bracket and Panel Nut), and 840014-51KIT (Quikclamp). Pair with the integrated gauge for quick setup and ensure enclosure clearance to maintain airflow and access to adjustment hardware.
Key specs include a maximum inlet pressure of 20 bar, an adjustable outlet range of 0.7 to 17 bar (10–247 psi), and a flow capacity of 125 dm3/s (265 scfm). The regulator is relieving, designed to vent excess pressure to protect downstream components, and operates over -20 to 65 °C, making it suitable for varied manufacturing environments while maintaining tight regulation.
Ideal for automated production lines, pneumatic tooling, and general purpose compressed air systems in manufacturing and packaging. Its compact 74 mm length, 70 mm width, and 186 mm height support panel mounting in space-constrained control cabinets, while the integrated gauge simplifies monitoring in routine maintenance and troubleshooting tasks across automotive, food & beverage, and process industries.
This Excelon Plus regulator aligns with common industry expectations, with CE-style compliance availability and SIL-capable configurations for safety-critical lines, plus IP-rated variants depending on enclosure and environment. Always verify the exact unit’s certification package in the datasheet and order confirmation to ensure it meets your plant’s regulatory requirements and safety programs.
Maintenance is supported by elastomer components and a dedicated service kit (FRLB84-KIT). Regular elastomer inspections and replacement with the FRLB84 elastomer kit help maintain seal integrity, reduce leak rate, and extend service intervals. The modular design also simplifies retrofits and upgrades within the Excelon Plus family, lowering lifecycle costs and downtime during plant changes or capacity expansions.
