Norgren R84G-4GK-RFE Pressure Regulator - Integrated Sensor
Part Number: R84G-4GK-RFE
Quick Summary
Norgren R84G-4GK-RFE pressure regulator is a precise air-pressure control device designed for automated pneumatic systems. Operators often battle fluctuating pressure, drift, and manual adjustments that slow cycles; integrated electronic pressure sensing and a push-to-lock knob help stabilize performance. Certification considerations for industrial components typically include CE marking, IP ratings, and SIL safety perspectives, depending on region and application. The Excelon Plus family brings robust reliability to packaging, robotics, and line feeding through a compact footprint, real-time feedback, and easy IO-Link compatibility for remote monitoring. These features translate to reduced downtime, predictable maintenance, and simpler supplier management in modern manufacturing plants. This combination supports safer, more efficient operations across high-volume production.

FAQs
Install using standard G1/2 fittings; ensure the regulator is mounted with proper clearance for the 167 mm height and 70 mm width. Connect the inlet to the supply and outlet to the actuator, using the Rc1/8 gauge port if feedback monitoring is required. Utilize the push-to-lock knob to set the target pressure and verify zero leaks with a suitable leak detector. IO-Link options may be used for remote monitoring when paired with compatible masters.
Key specs include a 0.3 to 4 bar adjustable outlet pressure, maximum inlet pressure of 20 bar, G1/2 port size, Rc1/8 gauge port, and a flow of 125 dm3/s (265 scfm). The regulator is Relieving type, designed for compressed air with operating temperature -20 to 65 °C, and a weight of 0.79 kg. Construction uses diecast aluminium body with acetal knob and nitrile elastomer seals.
While the data sheet does not list explicit certification markings, the Excelon Plus family is designed for robust industrial use and typical CE-compliant environments. For critical processes, confirm CE conformity and applicable IP ratings with your procurement team and ensure the specific installation complies with regional regulations and your plant’s safety standards.
The integrated electronic pressure sensor provides real-time feedback, reducing drift and the need for external sensors. This lowers maintenance costs, minimizes downtime due to manual recalibration, and enables easier remote monitoring via IO-Link. In high-volume lines, these benefits translate to higher throughput, more consistent product quality, and faster fault isolation.
The R84G-4GK-RFE supports IO-Link through the Excelon Plus ecosystem. Compatibility highlights include IO-Link master NC-ME-4A4B-12DLA and IO-Link I/O modules NC-HB-8A5F-12A0A, with IO-Link master PROFINET interfaces like NC-MP-4A4B-12DLA, enabling remote sensing, diagnostics, and streamlined configuration in production environments.
