Norgren R74G-3AK-RMG Excelon general purpose pressure regulator - 0.3-10 bar, with gauge
Part Number: R74G-3AK-RMG
Quick Summary
The Norgren R74G-3AK-RMG Excelon general purpose pressure regulator is a compact inline regulator that provides precise downstream pressure control for compressed air systems. In practice, engineers often struggle with space constraints and inconsistent pressure when retrofitting or expanding existing lines. While the dataset doesn’t itemize every certification, typical industrial practice emphasizes CE marking and robust protection against environmental exposure; verify compliance with local standards and supplier statements for your region. This model supports inline or modular installation, which accelerates commissioning, reduces piping complexity, and improves maintenance access, while maintaining reliable performance across a wide operating temperature range. Leveraging the Excelon platform, it delivers predictable control and smoother downstream pressure for automated processes including robotics, packaging, and tooling.

FAQs
The R74G-3AK-RMG supports common mounting accessories used with Norgren Excelon regulators, including 4315-02 Quikmount pipe adapters, 4324-50 'Universal' Bracket, 4314-51 Quikclamp, 4368-51 Neck Mounting Bracket, 4314-52 Quikclamp with wall mounting bracket, and related tamper-resistant and panel mounting options. These enable inline installation, rapid retrofits, and secure mounting in compact automation layouts.
Key specifications include a maximum inlet pressure of 20 bar and an adjustable outlet pressure range of 0.3 to 10 bar (4 to 145 psi). The regulator supports a flow of 105 dm3/sec (222 scfm), with a 3/8 inch port size and a 1/4 inch gauge port for monitoring, making it suitable for many standard compressed air applications.
Yes. The R74G-3AK-RMG is a relieving model, meaning it can reduce downstream pressure when the system becomes dead-ended. This feature protects downstream components and maintains safer operating conditions during fault or idle states, which is important in automated lines and tool stations.
Certification details are not listed in the provided data. For regulatory compliance, verify CE marking and any region-specific standards with your supplier. If your application requires safety or functional safety certification (such as SIL), confirm with Norgren or an authorized distributor and obtain official documentation before deployment in safety-critical systems.
Regular maintenance benefits from the tamper-resistant knob and a dedicated service kit (R74G-KITR) that supports quick part replacement. The balanced valve design yields stable pressure with minimal drift, enhancing process consistency and reducing scrap. In terms of ROI, the combination of modular installation, reliable pressure control, and ease of service typically lowers downtime and extends asset life in automated lines.
