IMI Norgren R84G-6GK-RFN Pressure Regulator - Relieving
Part Number: R84G-6GK-RFN
Quick Summary
R84G-6GK-RFN is a compact pressure regulator that stabilizes compressed air in automated production lines. Fluctuating pressure drives tool wear, shortens component life, and leads to inconsistent process results. The Excelon Plus platform uses a lightweight diecast aluminium body and a push‑to‑lock, tamper‑resistant knob for reliable, user‑friendly operation. Although the datasheet highlights performance ranges and materials, this design aligns with common industry expectations for safe, predictable pneumatic regulation. With rugged construction and straightforward mounting options, it supports scalable upgrades in automotive, packaging, and general automation environments.

FAQs
To install, ensure inlet and outlet lines match G3/4 ports and connect the Rc1/8 gauge port for pressure monitoring. Mount using suitable Excelon Plus mounting brackets (for example 840024-50KIT or 840068-51KIT as needed), then secure the push to lock knob to prevent tampering. Verify no air leaks and test at low pressure before full operation.
The regulator supports a maximum inlet pressure of 20 bar. The outlet pressure is adjustable from 0.3 to 4 bar (4 to 58 psi), providing flexible regulation across pneumatic actuators while safeguarding downstream components from over-pressurisation.
Yes. Its Relieving Excelon Plus design, 125 dm3/s flow capability, and robust aluminium body are well matched to automotive and other high-demand automation environments. The combination of compact size, reliable regulation, and easy mounting supports scalable deployment across multiple stations with consistent performance.
The data provided lists country of origin as United Kingdom and details on materials and performance, but it does not specify certification marks. For regulatory compliance, verify with the distributor or Norgren for CE or other regional certifications applicable to your installation and region.
Expect reduced downtime due to tamper-resistant adjustment, preventing unauthorized setpoint changes. The lightweight aluminium body and durable elastomers lower wear and replacement frequency. The regulator's precise control reduces tool wear and rejects variability, delivering measurable improvements in process consistency and overall equipment effectiveness (OEE).
