Norgren R84G-4GT-RFG Pressure Regulator - Integrated Gauge
Part Number: R84G-4GT-RFG
Quick Summary
Pressure regulator R84G-4GT-RFG ensures stable compressed air pressure for precision pneumatic actuation in automation systems. Fluctuating downstream pressure can lead to inconsistent tool performance, increased scrap, and longer setup times. Key certifications such as CE compliance, IP-rated protection, and SIL-ready configurations are standard expectations for industrial regulators, supporting safety, reliability, and maintainability in harsh environments. Designed as part of the Excelon Plus family, this unit combines a compact footprint with a flush-mounted gauge and a T-bar adjustment for quick field calibration. This translates to lower total cost of ownership and smoother integration into your existing panel layouts.

FAQs
Check that your supply line uses a standard G1/2 inlet and that the downstream circuit accepts 0.3–4 bar setpoints. The unit also features a flush-mounted gauge and a Rc1/8 gauge port, simplifying monitoring and diagnostics. For quick mounting, consider Excelon Plus mounting kits like 840014-51KIT or 840024-50KIT to secure the regulator in compact panels.
The regulator provides an adjustable outlet range of 0.3 to 4 bar (4 to 58 psi) and is a relieving type, meaning it vents excess pressure to ambient when the setpoint is exceeded. Maximum inlet pressure is 20 bar, allowing safe operation across typical plant air systems.
Yes. Its compact Excelon Plus design, integrated gauge, and T-bar adjustability make it ideal for general pneumatic actuation in automation and packaging lines. The G1/2 inlet, 0.3–4 bar regulation, and robust materials provide reliable performance in space-constrained panels and repeatable tool control.
Certifications are not explicitly listed in the provided data. For responsible selection, verify with the supplier or Norgren documentation whether CE, IP ratings, or SIL-ready configurations apply to this specific model in your jurisdiction and application.
The integrated gauge reduces misreadings and maintenance time, while the modular Excelon Plus system supports easy replacement and upgrades. Field-adjustability via the T-bar simplifies calibration, minimizing downtime. Over time, this can lower maintenance costs and improve overall equipment availability in production lines.
