Norgren R84G-3GK-RFE Excelon Plus Regulator with Sensor
Part Number: R84G-3GK-RFE
Quick Summary
R84G-3GK-RFE is a pressure regulator for compressed air systems, delivering precise outlet pressure control for automation equipment. This unit addresses drift and calibration challenges by integrating sensing directly into the regulator, reducing wiring complexity and sensor mounting time. The Excelon Plus family emphasizes modularity, compact weight, and tamper-resistant knob design, enhancing reliability in busy manufacturing environments. With a maximum inlet of 20 bar and an adjustable 0.3 to 4 bar output, it suits applications from general pneumatic actuation to precision tooling. CE-compliant expectations and IP-rated enclosure concepts are industry standards for this class of regulator, while IO-Link readiness opens data-enabled optimization. For procurement, its robust build and material choices translate into lower maintenance costs and longer service life in harsh plant conditions.

Integrated electronic pressure sensor delivers real-time feedback for closed-loop control, reducing wiring and installation time. This improves regulation accuracy and minimizes calibration drift in high-cycle lines. In practice, you gain faster stabilization after pressure changes and easier data capture for performance dashboards. Modular Excelon Plus design supports quick field adjustments with a push-to-lock knob that includes tamper-resistant features. This protects setups from inadvertent drifts during busy shifts, shrinking downtime and rework on assembly lines that rely on consistent pneumatic actuation. G3/8 port with Rc1/8 gauge port aligns with standard fittings and measurement devices, simplifying retrofit projects. The diecast aluminium body and POM bonnet provide a durable yet lighter package, easing installation in restricted spaces without sacrificing ruggedness or corrosion resistance in harsh factory environments. Relieving operation helps manage exhaust, improving responsiveness to dynamic loads and reducing backpressure in critical pneumatic circuits. With a flow rating of 125 dm3/sec (265 scfm), the regulator supports medium-to-high demand lines, delivering rapid stabilization and reduced energy waste in packaging, machine tending, or automation cells. IO-Link readiness enables data-driven maintenance and remote tuning through compatible masters and I/O modules. When paired with NC-ME-4A4B-12DLA, NC-HB-8A5F-12A0A, NC-HA-8A5F-12AAA, or NC-MP-4A4B-12DLA, operators gain visibility and control across the network. Material choices—nitrile elastomer seals, Acetal knob, and a diecast body—support long life and chemical compatibility in modern factories. Beyond performance, the R84G-3GK-RFE offers installation flexibility and compatibility with a wide range of pneumatic systems, including packaging, robotics, and tooling lines. Its compact footprint and consistent performance under -20 to 65 C extend service life in temperature-varied environments, while the integrated design reduces peripheral components and total cost of ownership.

FAQs
The R84G-3GK-RFE is designed for standard pneumatic installations using G3/8 thread connections and Rc1/8 gauge ports for pressure sensing. Its diecast aluminium body and POM bonnet simplify mounting in confined spaces, while the compact 86×70×167 mm footprint helps fit into crowded control cabinets. When retrofitting, ensure compatible fittings, check inlet pressure up to 20 bar, and align the outlet to the target 0.3–4 bar range for stable actuation.
The integrated electronic pressure sensor provides real-time pressure feedback to the control system, enabling closed-loop regulation and faster response to load changes. This reduces drift, minimizes manual calibration, and supports data logging via IO-Link. As a result, automation lines achieve tighter tolerances, lower cycle times, and improved repeatability without additional external sensing hardware.
Yes. With a maximum inlet of 20 bar and an adjustable 0.3–4 bar outlet, the R84G-3GK-RFE is capable of handling medium-to-high demand lines. Its 125 dm3/s (265 scfm) flow rate supports rapid stabilization after pressure changes, improving throughput in packaging, robotics, and precision tooling environments while maintaining compact dimensions for tight machine layouts.
The product line commonly aligns with CE expectations and supports robust enclosure concepts suitable for industrial environments. While SIL ratings aren’t specified in the provided data, consult the datasheet for exact safety certifications and ensure your integration complies with your facility’s regulatory requirements. For safety-critical roles, pair with appropriate SIL-rated safety components as needed.
To enable data-driven monitoring, pair the regulator with IO-Link masters and I/O modules listed in the Excelon Plus ecosystem, such as NC-ME-4A4B-12DLA (IO-Link master with EtherNet/IP), NC-MP-4A4B-12DLA (PROFINET master), NC-HB-8A5F-12A0A (I/O module, Standard), and NC-HA-8A5F-12AAA (I/O module, Auxiliary power). This enables sensor data access, remote tuning, and integration with PLC networks.
