Norgren R74G-4GK-RMN Excelon Regulator - 0.3-10 bar
Part Number: R74G-4GK-RMN
Quick Summary
R74G-4GK-RMN Excelon pressure regulator delivers reliable, adjustable pressure control for compressed air systems in automation environments. End users often contend with downstream pressure drift, pulsations, and dead-end conditions that degrade performance and increase energy use; this regulator addresses those challenges with a balanced valve design and built-in relief to protect downstream circuitry. Certification details aren’t listed in this data; however, Excelon regulators are engineered for rugged industrial use and provide compatibility for inline or modular installations in crowded plant layouts. By combining precise setting control, tamper-resistant adjustment features, and robust materials, this solution supports predictable performance, reduced maintenance, and easier procurement across pneumatic networks.

FAQs
The regulator supports both inline and modular installation, enabling flexible placement within existing or new pneumatic circuits. The compact footprint and standard G1/2 port thread simplify mounting to common manifolds, and the unit’s weight and materials are chosen for straightforward integration in crowded control panels while maintaining robust performance.
Key specs include a G1/2 port size, Rc1/8 gauge port, 0.3–10 bar outlet pressure range, and a maximum inlet pressure of 20 bar. The regulator operates over -34 to 80 °C and delivers a flow of 105 dm3/sec (222 scfm). These specs support consistent regulation across typical factory air networks.
Yes. The Excelon regulator uses a diecast aluminium body and bonnet with nitrile elastomer seals, designed for durability in demanding environments. With a 0.8 kg weight and a broad operating temperature range, it supports reliable performance across typical production floors, maintenance areas, and outdoor-rated installations where compressed air is essential.
This model is specified as without gauge. For gauge-equipped variants, look at related models in the Excelon range such as R84G-4GK-RMG. The standard regulator provides a gauge port Rc1/8 for optional instrumentation, and there are accessory and service kit options (R74G-KITR) to support maintenance and calibration as needed.
Maintenance benefits come from a durable European-designed build, tamper-resistant adjustment features, and a service kit option (R74G-KITR) that simplifies periodic calibration and parts replacement. The relieving function protects downstream equipment during dead-end events, reducing downtime and potential damage, contributing to lower overall operating costs and predictable ROI in automation lines.
