Quick Summary

Norgren R84G-4GK-RMN Excelon Plus pressure regulator controls compressed air pressure for automation systems. Engineers often battle fluctuating outputs and difficult-to-tune regulators that waste energy and impact cycle times. While the data does not list CE, SIL, or IP certifications, the Excelon Plus design emphasizes safety, reliability, and tamper-resistant adjustment to support critical manufacturing environments. With a G1/2 port, 0.3-10 bar outlet range, and relieving operation, it delivers consistent pressure control across pneumatic circuits. The compact form factor and robust materials reduce footprint while improving serviceability, making it a practical choice for OEMs and maintenance teams alike. This translates to lower operating costs and greater line uptime in continuous production setups.

Feature: Push-to-lock adjusting knob with built-in tamper-resistant feature. Benefit: Prevents accidental changes due to vibration, maintaining stable setpoints and reducing unplanned downtime in busy production lines. Application: Panel-mounted or machine-mounted regulators in automated assembly cells. It supports quick resets during changeovers without tools, improving changeover speed and consistency. Feature: Relieving regulator design. Benefit: Reduces back pressure and leakage, delivering faster response and cleaner pressure control for sensitive air tools and actuators. Application: High-speed pneumatic actuations in packaging or robotics. Feature: Compact weight and dimensions (0.59 kg, 167 mm height, 74 mm length, 70 mm width). Benefit: Easier integration in tight enclosures and on compact manifolds, enabling denser plumbing layouts and easier maintenance access. Application: OEM machinery with limited panel space. Feature: Robust material construction (die-cast aluminium body, acetal knob, POM bonnet, nitrile elastomers). Benefit: Enhanced durability and chemical resistance in harsh industrial environments, reducing replacement cycles and maintenance costs. Application: Harsh factory floors and wash-down areas. Feature: Flow capacity of 125 dm3/sec (265 scfm) and maximum inlet pressure of 20 bar. Benefit: Supports reliable performance across standard pneumatic circuits, enabling consistent actuation without over-sizing systems. Application: General automation lines and process equipment. Feature: Range and series alignment with Excelon Plus ecosystem (Range R84G, Series Excelon Plus). Benefit: Streamlined compatibility with mounting kits and accessory options for faster install and upgrades. Application: Retrofit projects and multi-vendor assemblies for scalable lines.

FAQs

Install with a G1/2 male port connection and Rc1/8 gauge port for monitoring. Use the Excelon Plus mounting options (such as Quikclamp kits or general mounting brackets) to secure the regulator in the panel or machine frame. The knob is push-to-lock for tamper resistance, helping maintain the set pressure during vibration or frequent changeovers.
Medium is compressed air. Maximum inlet pressure is 20 bar. Outlet pressure is adjustable from 0.3 to 10 bar (4 to 145 psi). Gauge port is Rc1/8, and the unit relieves to atmosphere. These specs support stable control across standard pneumatic circuits.
Yes. The R84G-4GK-RMN is part of the Excelon Plus family and leverages compatibility with mounting kits such as 840014-51KIT (Quikclamp) and 840024-50KIT (General Mounting Bracket), enabling fast installation and clean panel layouts.
Regularly inspect the elastomer seals (Nitrile rubber) and ensure the adjusting knob remains tamper-resistant. If elastomer wear is suspected, use the FRLB84-KIT Elastomer Service Kit for elastomer replacement. The die-cast aluminium body and POM bonnet are designed for durability in oily or dusty environments, reducing frequent replacements.
Expect improved process stability due to precise 0.3-10 bar control, reduced waste from over-pressurization, and less downtime from drift thanks to the tamper-resistant knob. The compact form factor simplifies installation, enabling denser manifolds and easier maintenance, which translates to lower operating costs and higher line uptime.
