Norgren R84G-4AT-RMN Excelon Plus Regulator Relieving
Part Number: R84G-4AT-RMN
Quick Summary
Norgren R84G-4AT-RMN Excelon Plus pressure regulator delivers precise air pressure control for automation lines. Engineers often contend with weight, size, and setup complexity when retrofitting compact pneumatic systems. While formal certifications are not listed here, verify CE, IP, or SIL where applicable to meet your safety and reliability standards. Designed to reduce installation time and lifecycle costs, it pairs with Excelon Plus mounting kits and gauges to fit tight spaces and evolving lines. The regulator's 0.3–10 bar range and 20 bar inlet support a wide array of pneumatic tasks, while the T-bar adjustment enables fine, repeatable control. This combination helps streamline maintenance and expandability in modern manufacturing environments.

Compact by design, the Excelon Plus R84G-4AT-RMN reduces weight and footprint without sacrificing performance. This lightweight, modular system enables flexible configurations, faster line changes, and simpler maintenance, delivering smaller enclosures and lower installation costs in OEM facilities. The T-bar adjustment provides precise outlet control from 0.3 to 10 bar, with a robust 20 bar maximum inlet, meaning reliable regulation across diverse machines and cycles. A relieving regulator speeds depressurization, improving cycle times and safety in clamping and pick-and-place applications. With a flow rating of 125 dm3/sec (265 scfm), the unit supports multiple actuators or manifolds, boosting overall system throughput. Durable diecast aluminium body, zinc-plated knob, POM bonnet, and nitrile elastomer seals ensure long service life in harsh environments. Compatibility with Excelon Plus mounting kits (Quikclamp) and gauge solutions (Gauge Adaptor Kit) simplifies installation and future upgrades. Maintenance is further supported by elastomer service kits (FRLB84-KIT), reducing downtime and total cost of ownership. OEMs can standardize on this regulator family to minimize spare parts variety while maintaining performance across lines.
