Norgren R72G-3GK-RFN Excelon General Purpose Regulator - Relieving
Part Number: R72G-3GK-RFN
Quick Summary
Excelon general purpose regulator is a precision pneumatic pressure control device for automated manufacturing lines. Engineers often contend with pressure swings and dead-ended sections that disrupt performance and waste energy. This Excelon design supports common compliance needs with CE-related expectations and a relief option to protect downstream circuits, while offering robust inline or modular installation. With a compact aluminum-zinc body, tamper-resistant adjustment, and a proven range of operating temperatures, it delivers reliable control in demanding environments. For engineers, this translates to fewer field adjustments, tighter process control, and reduced unplanned downtime across production lines. The product is part of the Excelon family, designed for reliable performance in compressed air systems.

Inline or modular installation is supported by the Excelon regulator, enabling flexible placement in compact frames or larger manifolds. This translates to shorter installation times, fewer fittings, and easier field upgrades, reducing overall project lead times. It is ideal for automation panels where space and future reconfiguration are considerations. Balanced valve design provides consistent pressure control across load changes, improving tool performance and precision. The result is tighter process control, reduced part wear, and less rework in high-cycle applications such as pneumatic clamping and coupling systems. Users benefit from predictable output even as line demand fluctuates. Relieving models actively reduce downstream pressure when the system is dead-ended, enhancing safety and preventing backflow or pressure spikes. For life-cycle costs, this means fewer unplanned shutdowns and simpler compliance testing in manufacturing environments. This feature is particularly valuable in multi-station conveyors and automated tooling where dead-end events are possible. Push-to-lock adjustment with tamper-resistant accessory helps maintain set-point integrity in busy panels and protected environments. Operators can quickly secure settings, while engineers can rely on consistent performance across shifts. This reduces maintenance calls and rework caused by inadvertent changes. R72G-3GK-RFN uses a zinc pressure die-cast body, acetal bonnet, and nitrile elastomer seals to withstand industrial duty, with operating temperature from -34 to 65 °C and a maximum inlet pressure of 20 bar. Gauge port Rc1/8 supports integration with standard test and monitoring equipment, while dimensions and weight (49 mm height, 106 mm length, 51 mm width, 0.36 kg) fit common control cabinets. The regulator delivers up to 33 dm3/s (70 scfm) of flow for reliable supply.

FAQs
Install the R72G-3GK-RFN by mounting it on a suitable panel or inline manifold using the G3/8 port connections. Use the Rc1/8 gauge port for monitoring and test connections. Ensure the maximum inlet pressure of 20 bar is not exceeded and verify that the relief feature is configured to protect downstream circuits. Follow the included installation guide for torque and sealant recommendations.
The regulator provides an adjustable outlet range of 0.3 to 4 bar (4 to 58 psi) with a maximum inlet pressure of 20 bar. It is a relieving type, allowing downstream pressure to be reduced when the system is dead-ended, which enhances safety and stability in pressure-critical applications.
Yes. The Excelon design supports inline installation or modular configurations, enabling flexible placement in control panels or manifolds. This simplifies future upgrades, reduces installation time, and supports common automation architectures where space and reconfiguration may change over the plant lifecycle.
The provided data does not specify certifications. For regulated environments, confirm CE marking and any region-specific compliance with your supplier or Norgren, and ensure the unit configuration meets your plant’s regulatory requirements. If needed, request documentation for additional standards to support your QA and commissioning processes.
The push-to-lock knob with tamper-resistant features helps prevent unintended set-point changes, reducing drift and maintenance calls. This supports consistent tool performance, decreases downtime from misadjustments, and improves uptime for high-cycle pneumatic systems such as conveyors and automated tooling.
