Norgren R84G-3GT-RFG Pressure Regulator - Integrated Gauge
Part Number: R84G-3GT-RFG
Quick Summary
Norgren R84G-3GT-RFG is a general purpose pressure regulator designed for compressed air systems in automation and manufacturing. Engineers often face bulky regulators, limited visibility, and installation complexity that slow line changes. CE compliance and robust protection ratings, with an integrated gauge option, address global standards and field reliability. Designed for quick integration, this Excelon Plus regulator reduces footprint while delivering precise 0.3 to 4 bar output, supporting efficient pneumatic systems. For design engineers, that means faster commissioning and fewer field returns, while procurement benefits from common spare parts and consistent performance across lines. In addition to the integrated gauge, the Excelon Plus family offers modular ease of maintenance and compatibility with a range of mounting and service kits.

The integrated flush-mounted gauge and T-bar adjustment provide immediate visibility and precise control with minimal surface intrusion, enabling faster start-ups and fewer calibration steps, a clear win for uptime and energy efficiency. The lightweight diecast aluminium body and compact footprint reduce weight while maintaining durability, making it ideal for space-constrained panels and crowded automation bays. With a relieving design and a maximum inlet of 20 bar and an adjustable outlet from 0.3 to 4 bar, operators gain stable, quick-response regulation for critical tooling and pick-and-place lines. Compatibility with Excelon Plus accessories — such as mounting brackets (840024-50KIT) and Quikclamp kits (840014-51/52KIT) — simplifies installation and future reconfiguration. Modular construction and nitrile elastomer seals offer reliable operation in fluctuating ambient temperatures and oily air streams while minimizing maintenance. The product’s compact dimensions (186 mm height, 70 mm length, 74 mm width) and weight of 0.79 kg make it straightforward to specify for standard panels and enclosures.

FAQs
Install using standard G3/8 pipe fittings and mount with compatible Excelon Plus brackets (e.g., 840024-50KIT) or Quikclamp kits (840014-51/52KIT). Connect the Rc1/8 gauge port for monitoring and set the T-bar to the desired 0.3-4 bar range. Ensure the inlet pressure does not exceed 20 bar and verify leak-free connections after mounting.
Key specs include outlet pressure 0.3 to 4 bar, maximum inlet pressure 20 bar, relieving type, flow about 125 dm3/sec, G3/8 port size, Rc1/8 gauge port, and operating temperature range -20 to 65 °C. The regulator weighs 0.79 kg and uses a diecast aluminium body with nitrile elastomer seals.
Yes. It is designed for the Excelon Plus family and works with mounting options such as 840024-50KIT General Mounting Bracket and 840014-51/52KIT Quikclamp sets, enabling rapid installation and flexible panel layouts.
The Excelon Plus range typically supports essential industry standards, including CE marking for European compliance and robust protection ratings for industrial environments. Always verify the exact certification for your region and configuration in the datasheet or brochure.
The integrated gauge reduces setup time, the compact form factor eases panel design, and modular mounting minimizes rework. Together with stable 0.3-4 bar regulation and low-maintenance elastomers, this lowers energy waste, shortens changeovers, and reduces maintenance costs over the asset life.
