Norgren R74M-6GK-RMN Pressure Regulator - Relieving
Part Number: R74M-6GK-RMN
Quick Summary
Norgren R74M-6GK-RMN pressure regulator provides precise air pressure control for automation lines. Engineers often struggle with compact layouts, multi-point regulation, and delivering consistent pressure across a growing regulator network. In the Excelon family, inline or modular installation is supported, with manifolds handling up to six regulators without booster signals. This model offers a 0.3 to 10 bar outlet range and a G3/4 port, enhancing reliability and scalability in busy plants. Designed for rugged industrial environments, it supports Excelon manifolds and scalable compressed air networks.

Pressure Regulators
Feature → Business Impact → Application: Excelon design enables inline or modular installation, reducing panel footprint and simplifying retrofits, which cuts installation time and cost while improving future scalability across multiple regulators in automated lines. This supports lean maintenance and quicker expansion of air regulation networks in manufacturing plants. Feature → Business Impact → Application: Outlet pressure adjustment from 0.3 to 10 bar allows precise control for diverse pneumatic tasks, improving process stability and reducing part wear due to pressure fluctuations in assembly and packaging lines. Application: Suitable for high-precision pick-and-place, CNC tooling feeds, and automated testing benches where tight pressure tolerance is critical. Feature → Business Impact → Application: Relieving regulation improves venting and pressure relief response, enhancing safety and rapid fault-handling in multiplex regulator manifolds typical of automated transfer lines. Application: Used in multi-point regulators where quick venting minimizes cycle times and avoids overpressure events.

FAQs
The Excelon design supports inline or modular installation, allowing up to six regulators on a single manifold without booster signals. Use the G3/4 port connections for supply and the Rc1/8 gauge port for monitoring. Ensure proper orientation and secure mounting to maintain alignment and accurate pressure control across the entire bank.
Outlet pressure is adjustable from 0.3 to 10 bar (4 to 145 psi), with a maximum inlet pressure of 20 bar. The regulator delivers a nominal flow of 105 dm3/sec (222 scfm), suitable for multi-point regulation in compact automation panels.
Yes. The relieving regulation mode provides stable outlet pressure with rapid venting on demand, while the knob adjustment offers fine-tuning. With a robust diecast aluminium body and nitrile elastomer seals, it supports consistent performance in demanding production environments.
Check the product datasheet for your region’s required certifications (CE marking and other regulatory marks are commonly applicable for industrial automation components). The datasheet for the R74M-6GK-RMN provides detailed compliance information and any part-specific certification notes. You can also review the downloadable datasheet linked on the product page.
Service kits are listed for related regulators in the Excelon line (e.g., 4381-700 Pressure Regulators). For ongoing maintenance, verify compatibility with 4355-51 accessories (Tamper Resistant Cover and Wire) and plan periodic inspection of the adjusting knob, gauge port, and elastomer seals to sustain performance in continuous-duty applications.
