Norgren R84G-3AK-RMG Pressure Regulator - Integrated Gauge
Part Number: R84G-3AK-RMG
Quick Summary
The Norgren R84G-3AK-RMG pressure regulator provides precise compressed-air control for general automation tasks. Many engineers struggle with bulky regulators and hard-to-read gauges that slow setup and invite misadjustments. The Excelon Plus design delivers consistent outlet pressure from 0.3 to 10 bar with a 20 bar maximum inlet and a relieving function. Its compact, lightweight form, flush-mounted integrated gauge, and tamper-resistant push-to-lock knob streamline installation and help prevent unauthorized changes. For OEMs and maintenance teams, this delivers faster commissioning, lower panel depth, and reliable, repeatable pneumatic regulation across industrial applications.

Feature: Integrated flush-mounted gauge and compact weight. Business Impact: Faster, more accurate commissioning and easier panel installation; fewer leaks due to streamlined mounting. Application: Ideal for tight-panel automation zones where visual confirmation of outlet pressure matters. Feature: Push-to-lock adjusting knob with tamper-resistant design. Business Impact: Reduces the risk of unintentional pressure changes during operation, improving process stability. Application: Packaging lines and high-cycle conveyors where consistent regulation is critical. Feature: Relieving regulator with 0.3–10 bar output. Business Impact: Efficient venting minimizes back-pressure and improves rapid response to load changes. Application: General pneumatic control in machine tools and assembly cells. Feature: Robust MIP materials and durable construction (Diecast aluminium body, Acetal knob, POM bonnet, Nitrile elastomers). Business Impact: Enhanced durability in challenging environments and longer service life. Application: Harsh industrial environments with exposure to oils and particulates. Feature: Wide operating envelope and mounting flexibility (−20 to 65 °C, 20 bar max inlet, 3/8" PTF port, 1/8" gauge port). Business Impact: Broad environmental compatibility and seamless integration with standard pneumatic systems. Application: OEM machines, conveyors, and automation platforms that demand reliable performance across shifts. Feature: Excelon Plus ecosystem support (compatibility with mounting brackets, gauges, and service kits). Business Impact: Simplified upgrade paths and maintenance planning, lowering total cost of ownership. Application: Systems that require modular expansion and scheduled elastomer service.

FAQs
Begin by confirming port sizes: the regulator uses 3/8" PTF supply ports and a 1/8" PTF gauge port. Mount the unit on a suitable panel or bracket (consider 840024-50KIT for a General Mounting Bracket). Connect supply fittings to the 3/8" ports, ensure gauge orientation is readable, and secure the Push-to-Lock knob to prevent accidental adjustment. Check for leaks with a low-pressure test, then calibrate the outlet to the desired 0.3–10 bar range. The flush gauge simplifies real-time verification during setup and maintenance.
Medium is compressed air. Operating temperature ranges from −20 to 65 °C (−4 to 149 °F). Maximum inlet pressure is 20 bar. Outlet pressure is adjustable from 0.3 to 10 bar (4 to 145 psi). It is a relieving regulator with a flow capacity of 125 dm3/s (265 scfm). Gauge port is 1/8" PTF, and the knob adjustment is designed to be tamper-resistant.
This regulator is well-suited for general pneumatic regulation in automation lines, conveyors, and packaging equipment. The integrated gauge provides quick pressure visibility, while the compact Excelon Plus design minimizes panel depth. The relieving function helps manage venting on load changes, contributing to stable process control in high-cycle or space-constrained installations.
Certification details are not listed in the provided data. For CE, SIL, IP ratings, or region-specific approvals, consult the product literature or your Norgren distributor. The unit is designed for robust industrial use, but formal certifications should be verified against your project’s regulatory requirements before deployment.
The Excelon Plus R84G-3AK-RMG delivers reduced panel space and weight, aiding faster installation and less fatigue during handling. The push-to-lock knob minimizes unauthorized changes, supporting process stability. When paired with service kits like FRLB84-KIT, and mounting accessories such as 840024-50KIT, preventive maintenance becomes simpler, reducing downtime and extending regulator life—delivering tangible ROI for OEMs and maintenance teams.
