Norgren R74M-4GK-RMN Excelon regulator - Relieving
Part Number: R74M-4GK-RMN
Quick Summary
R74M-4GK-RMN Excelon manifold pressure regulator provides stable compressed air pressure for automation manifolds. Engineers struggle with inconsistent supply and space constraints when expanding multi-regulator banks. Certification details such as CE, SIL, or IP ratings are not listed in the data; verify with Norgren for regulatory compliance. In practice, the Excelon design supports inline or modular installation, simplifying panel layout and maintenance while delivering reliable regulation. From a business perspective, the compact form, modular mounting options for up to six regulators, and durable materials translate to faster deployments and reduced lifecycle costs. Additionally, the design facilitates easy integration with Norgren accessories such as tamper-resistant covers and mounting clamps, supporting long-term reliability in harsh industrial environments.

FAQs
The R74M-4GK-RMN supports inline and modular installation, enabling flexible panel layouts and scalable regulator banks. It is compatible with Norgren mounting accessories such as the 4355-51 tamper-resistant cover and Quikclamp kits (4214-51, 4214-52), which simplifies retrofits and reduces assembly time on existing equipment.
Key specs include a G1/2 inlet, 0.3–10 bar adjustable outlet, 20 bar maximum inlet pressure, a relapse-relieving configuration, and a gauge port Rc1/8. Flow is rated at 105 dm3/sec, with an operating temperature range of −34 to 80 °C, suitable for most standard industrial environments.
Yes. The Excelon R74M-4GK-RMN is designed for inline and modular installations and supports manifolds typically up to six regulators without booster signals, making it well-suited for distributed regulator banks in packaging, automation, and light to medium-duty process lines.
Consider service kits like 4381-700 (Pressure Regulators) for routine maintenance. The regulator uses durable diecast aluminium bodies, Acetal resin adjusting knobs, and nitrile elastomer seals, which influence seal replacement intervals. Compatibility with existing spare parts can minimize downtime during service windows.
