Norgren R84G-3GT-RSG Pressure Regulator - Integrated Gauge
Part Number: R84G-3GT-RSG
Quick Summary
Norgren R84G-3GT-RSG pressure regulator provides precise, adjustable control of compressed air pressure for general‑purpose systems. Engineers often contend with bulky regulators that complicate panel installation and maintenance in tight spaces. For planning and compliance, verify CE marking, IP ratings, and SIL capability with the official datasheets, since certifications are critical for safety approvals. The Excelon Plus design combines a lightweight diecast aluminum body with a flush-mounted integrated gauge, while the T-bar adjustment simplifies setpoint changes, delivering faster commissioning and reduced downtime in production lines. This translates to lower lifecycle costs and improved process stability across automated systems.

Feature → Business Impact → Application: The Excelon Plus R84G-3GT-RSG uses an integrated flush-mounted gauge, reducing panel depth and simplifying on-site calibration, which lowers installation time and field maintenance costs in compact control cabinets. This enables reliable pressure control in bottleneck lines and high-cycle applications. Feature → Business Impact → Application: Relieving regulation protects downstream equipment from overpressure events, improving system safety and reducing unplanned downtime in milling, casting, and packaging lines where pressure transients are common. Feature → Business Impact → Application: T-bar adjustment offers quick, repeatable setpoints, enabling tight process control in general‑purpose pneumatic systems and robotics cells without complex tuning. Feature → Business Impact → Application: Diecast aluminium body and nitrile elastomer seals deliver robust performance in harsh factory environments, extending service life and reducing spare part usage in continuous operation lines. Feature → Business Impact → Application: Compatible with Excelon Plus mounting brackets, quikclamps, and integrated gauge kits, enabling modular installations and faster retrofits in existing panels and new builds.

FAQs
Install the regulator using standard panel mounting practices for Excelon Plus components. Use the panel nut and mounting options (for example 840048-89KIT and related mounting accessories) to secure the unit, connect the G3/8 port for supply, and route the Rc1/8 gauge line. Ensure the gauge is oriented for easy readability and verify clearance for the integrated T-bar adjustment knob during commissioning.
The R84G-3GT-RSG provides an adjustable outlet from 0.7 to 17 bar, suitable for general‑purpose regulation. The maximum inlet pressure is 20 bar, allowing safe operation with standard compressed air systems while maintaining accurate downstream control if supply fluctuations occur.
This model is a relieving regulator, meaning it ventes excess pressure to atmosphere when the downstream pressure exceeds the setpoint. This feature protects sensitive downstream equipment, maintains stable regulation under load fluctuations, and reduces the risk of overpressure in the line.
Compatible accessories include the Excelon Plus Panel Nut kit (840048-89KIT) for panel mounting, the integrated gauge kit (840073-02KIT) for enhanced monitoring, mounting brackets (840024-50KIT, 840068-51KIT), and quick-clamp options (840014-51KIT, 840014-52KIT). Service kits such as FRLB84-KIT are also available for elastomer replacement, ensuring long-term reliability.
Benefits include a compact, lightweight design (0.59 kg) with a flush-mounted gauge for fast diagnostics, T-bar adjustability for precise setpoints, and durable materials (diecast aluminum body and nitrile elastomers) that resist wear in industrial environments. Together, these features reduce downtime, extend service intervals, and improve process consistency in automated manufacturing lines.
