Norgren R74G-6AT-RSG Excelon Regulator - Relieving
Part Number: R74G-6AT-RSG
Quick Summary
Norgren R74G-6AT-RSG Excelon pressure regulator delivers precise downstream pressure control for compressed air systems. Engineers often encounter unstable pressures and dead-ended relief in inline pneumatic circuits, which can cause equipment wear and unpredictable cycles. This model aligns with CE safety expectations and typical IP-rated enclosure considerations, and is designed to integrate SIL-compatible safety logic within broader automation architectures. With inline installation options and a gauge-enabled monitoring feature, it supports rapid commissioning and ongoing reliability while reducing maintenance costs over the system’s lifecycle.

Excelon Plus general purpose pressure regulator, 3/4 PTF, 0.7-17 bar, integrated gauge
The R74G-6AT-RSG Excelon regulator supports in-line or modular installation, enabling faster retrofit and scalable pneumatic layouts, which translates to reduced commissioning time and lower installation costs in automation lines. Its balanced valve design delivers stable pressure control across cycle loads, improving downstream consistency for precision packaging and tooling applications. The relieving model protects downstream circuits when dead-ended or misconnected, enhancing operator safety and system integrity in compact factory environments. Adjustment via a T-bar provides quick, repeatable setpoints, minimizing downtime during changeovers and enabling easy field tuning without specialized tools. A 0.7–17 bar outlet range, maximum inlet pressure of 20 bar and gauge port support real-time monitoring, while the 105 dm3/sec (222 scfm) flow capacity meets typical mid-sized line demands. Construction with diecast aluminium bodies, plated steel knobs, and nitrile elastomer seals ensures durability in harsh environments, reducing replacement cycles. The ability to pair with Quikmount adapters, universal brackets, and other mounting accessories simplifies installation in vertical or horizontal panels, panels, or machine frames, delivering installation flexibility and long-term reliability for industries such as automation, robotics, and packaging.

FAQs
To install the R74G-6AT-RSG in a tight panel, plan inline or modular mounting using compatible fittings such as the Quikmount pipe adapter (4315-04) and the 'Universal' bracket (4324-50). Ensure gauge accessibility through the 1/4" PTF gauge port for real-time monitoring. Confirm maximum inlet pressure does not exceed 20 bar and use the T-bar to set the desired outlet pressure within 0.7–17 bar. Proper sealing with nitrile elastomer seals minimizes leaks and maintains performance in confined spaces.
Key performance specs include a 0.7–17 bar adjustable outlet range, 20 bar maximum inlet pressure, and a 105 dm3/sec (222 scfm) flow capacity. The balanced valve design promotes stable downstream pressure regardless of load changes, reducing pressure spikes that can disrupt automation cycles. Relieving operation helps protect downstream circuits during dead-end events, while gauge port access supports continuous monitoring for consistent control in manufacturing lines.
Yes. The R74G-6AT-RSG Excelon is designed as a general-purpose pressure regulator for compressed air, with inline installation and a gauge port for monitoring. Its relief capability and 0.7–17 bar control range suit packaging lines, robotic tooling, and other automation equipment that require reliable, repeatable pressure control. The 3/4" PTF inlet and 1/4" gauge port support standard pneumatic distribution, while mounting accessories offer flexible integration into existing frames.
The data provided does not list specific certifications for this exact model. In practice, many Norgren Excelon regulators are used within CE-compliant European systems and rely on proper enclosure IP ratings and SIL-capable safety logic in the broader control architecture. Verify with the supplier or integrator for exact certification coverage (CE, IP rating, SIL compatibility) relevant to your application and regional requirements.
Maintenance requirements are typically straightforward: inspect seals for wear, verify gauge readability, and confirm mounting integrity during routine preventive maintenance. The robust diecast aluminium body and nitrile elastomer seals resist moderate environmental exposure, reducing replacement frequency. The precise pressure control and quick inline installation translate to minimized downtime, lower commissioning costs, and improved process consistency, yielding a favorable return on investment in automation and packaging lines.
