Norgren R84G-3GT-RMG Pressure Regulator - Relieving
Part Number: R84G-3GT-RMG
Quick Summary
Norgren R84G-3GT-RMG pressure regulator provides precise compressed-air control for compact pneumatic automation systems. Plant floors often struggle with fluctuating downstream pressure, bulky devices, and maintenance-heavy setups that slow throughput. While the data highlights core performance specs, engineers should consider industry standards such as CE marking and IP-rated housings where applicable, and SIL configurations for safety-critical lines. The Excelon Plus design emphasizes a flush-mounted integrated gauge and a lightweight chassis, delivering faster commissioning and more reliable monitoring. In practice, these attributes translate to lower installation time, easier service, and improved total cost of ownership for OEM panels and retrofit projects.

Integrated gauge and flush-mounted gauge reduce commissioning time and simplify diagnostics, enabling quicker fault isolation and less downtime in control cabinets. The business impact is measurable: faster start-up, better process visibility, and fewer field visits for gauge checks, which is especially valuable on high-mix production lines. Application-wise, the R84G-3GT-RMG is well-suited for compact panels where space is at a premium and reliable pressure regulation is essential for actuators and valves. The G3/8 port size, 0.3–10 bar outlet range, and 20 bar max inlet support high-flow actuation with stable downstream pressure, improving cycle times for robotics and pick-and-place equipment. T-bar adjustment delivers precise setpoint control, while the 125 dm3/sec flow ensures adequate performance for medium-to-high-demand circuits. The diecast aluminium body, nitrile elastomer seals, and POM bonnet provide robust operation across industrial temperatures and vibration. This regulator’s modular mounting options, including Excelon Plus brackets and Quikclamp kits, simplify installation and field retrofit, reducing time-to-value and spare-part diversity. In real-world terms, engineers appreciate the lighter weight (0.79 kg) and compact footprint (186 x 70 x 74 mm), which reduces panel load and allows denser layouts. With integrated gauge, the device supports proactive maintenance strategies and can be paired with the Excelon Plus service kits FRLB84-KIT for elastomer replacements, extending lifecycle and reducing total cost of ownership.

FAQs
Install on a suitable panel or enclosure using Excelon Plus mounting options such as 840024-50KIT (general mounting bracket) or 840068-51KIT (neck mounting bracket and panel nut). Connect the G3/8 inlet and Rc1/8 gauge port per your pneumatic circuit diagram, then set the outlet pressure using the T-bar adjustment within the 0.3–10 bar range. Ensure ambient temperature stays within -20 to 65 °C and use compatible elastomer seals (nitrile) for your media.
Key specs include G3/8 port size, Rc1/8 gauge port, maximum inlet pressure of 20 bar, outlet pressure adjustment range of 0.3–10 bar, relieving regulation, and a flow capacity of 125 dm3/s (265 scfm). Operating temperature range is -20 to 65 °C, with a compact diecast aluminium body and integrated gauge for straightforward monitoring.
Yes. The regulator is designed for Excelon Plus mounting ecosystems and is compatible with brackets like 840024-50KIT and 840068-51KIT, as well as Quikclamp options 840014-51KIT and 840014-52KIT, enabling flexible orientations and fast installations in control panels and machine frames.
While the data here does not list specific certifications, when selecting for a facility you should verify CE marking and IP-rated enclosures for your environment, and consider SIL configurations for safety-critical applications. Always confirm with the supplier to ensure the exact model configuration meets your regulatory and safety requirements.
The flush-mounted integrated gauge simplifies pressure monitoring and reduces calibration time, while the modular mounting and compatible Makings kits decrease installation time and spare-part diversity. Together, these features can lower maintenance labor, minimize unscheduled downtime, and shorten the payback period in high-uptime manufacturing environments.
