Norgren R73G-2GK-NMN Valves - Excelon regulator, 0.3-10 bar
Part Number: R73G-2GK-NMN
Quick Summary
The R73G-2GK-NMN Excelon pressure regulator delivers precise compressed air control for automated panels. Unstable downstream pressure can cause actuator chatter, slower cycles, and premature wear on pneumatic systems. Designed to meet CE compliance, with IP-rated housing options and SIL-ready configurations, it supports safe, compliant operation in demanding environments. In-line or modular installation helps reduce piping complexity and makes retrofits easier across existing lines. With a balanced valve design, push-to-lock knob, and tamper-resistant accessory, maintenance is simpler and downtime is minimized. In today’s pneumatic networks, reliable pressure regulation translates directly to improved cylinder response, energy efficiency, and longer equipment life. Secondary benefits include predictable response across a 0.3 to 10 bar range and compatibility with standard G1/4 fittings.

Feature: Excelon design enables in-line or modular installation. Business Impact: reduces installation time and allows flexible positioning to fit existing layouts. Application: ideal for automating control panels where space is constrained or reconfiguration is common. Feature: Balanced valve design for stable pressure control. Business Impact: minimizes downstream fluctuation, improving actuator precision and cycle consistency. Application: essential in high-speed manufacturing lines with multiple actuators. Feature: Push-to-lock adjusting knob with tamper-resistant accessory. Business Impact: prevents accidental setting changes, enhancing process reliability and operator control. Application: suitable for harsh factory floors and environments with frequent line changes. Feature: Non-relieving outlet with 0.3–10 bar adjustment and 20 bar max inlet. Business Impact: retains set pressure under transient loads, protecting downstream devices and reducing leaks. Application: supports stable regulation across typical pneumatic circuits. Feature: Robust materials and construction (die-cast aluminium body, acetal adjusting knob, zinc bonnet, nitrile elastomers). Business Impact: provides durability in challenging environments while maintaining long-term accuracy. Application: suitable for industrial environments with exposure to dust, vibration, and temperature variation. Feature: Gauge port Rc1/8 and standard port size G1/4 with 60 dm3/s flow. Business Impact: ensures compatibility with common fittings and adequate flow for single or multi-actuator systems. Application: retrofits and new installations across automation lines. Feature: Broad accessory ecosystem (Quikclamp, tamper-resistant cover, service kits, universal brackets). Business Impact: simplifies installation, maintenance, and future servicing, reducing downtime. Application: supports scalable maintenance programs and quick component replacement.

FAQs
The Excelon regulator supports in-line and modular installation, enabling flexible mounting alongside existing piping and brackets. You can attach it to neck or universal brackets as needed (examples include 4461-50 Neck Mounting Bracket and 4424-50 Universal Bracket). Use compatible fittings (G1/4 port, Rc1/8 gauge port) to minimize space and simplify retrofits.
Outlet pressure is adjustable from 0.3 to 10 bar, with a maximum inlet pressure of 20 bar. The device is a non-relieving regulator with a balanced valve design to maintain steadier downstream pressure during load changes, supporting reliable operation of pneumatic actuators.
Yes. It’s designed as a general purpose Excelon regulator for compressed air, ideal for automation panels, cylinders, and multiple actuators requiring stable regulation. Its 60 dm3/s flow capacity accommodates typical panel and line demands, while the compact G1/4 port footprint eases integration.
The Excelon line is designed with CE compliance and available IP-rated housing options. SIL-ready configurations are offered to support safety-critical control schemes, enabling compliant operation in demanding industrial environments.
Service kits are available (R73G-KITR) for field maintenance, along with installation guides and accessory support such as Quikclamp variants and tamper-resistant covers. Regular service helps preserve regulation accuracy, reduce downtime, and extend equipment life, delivering measurable ROI over time.
