Norgren R73G-2GK-RMN Pressure Regulator - Relieving
Part Number: R73G-2GK-RMN
Quick Summary
Norgren R73G-2GK-RMN pressure regulator is a precision device that maintains stable downstream pressure in compressed air systems for automation and manufacturing applications. In busy production lines, fluctuating pressure and dead-ending waste energy, reduce cycle efficiency and strain equipment; this model’s relieving design helps prevent overpressure and protects downstream tools. The Excelon line commonly supports CE marking and RoHS-compliant materials, with durable construction suited to industrial environments, while a balanced valve design ensures accurate regulation. Inline or modular installation options simplify retrofits and future expansion, and the 0.3–10 bar output range with a G1/4 port enables easy integration with standard piping. For procurement teams, this combination translates to improved uptime, predictable performance, and lower operating costs over the system lifecycle.

Relieving design provides downstream protection against overpressure and dead-end conditions, reducing tool wear and avoiding unexpected shutdowns in assembly lines. This translates to lower maintenance costs and higher overall equipment effectiveness in automated packaging and production cells. A balanced valve design delivers stable pressure with fast response to setpoint changes, minimizing pressure spikes that can compromise precision grinding, clamping, or pneumatic handling tasks. Inline or modular installation flexibility supports scalable retrofits across evolving plant layouts, enabling easier maintenance and faster commissioning without heavy system rework. The knob-adjustment with push-to-lock tamper-resistant accessory secures critical setpoints in high-traffic facilities, reducing drift and unauthorized changes while preserving safety. Durable materials—die-cast aluminium body, zinc bonnet, acetal knob, and nitrile elastomers—support long service life in demanding environments and maintain performance across a wide operating temperature range. With G1/4 port size and Rc1/8 gauge port, compatibility with standard piping and instrumentation is straightforward, while the 20 bar maximum inlet and 0.3–10 bar outlet range deliver precise control for general purpose regulating tasks in automation, testing rigs, and industrial robotics.

FAQs
The R73G-2GK-RMN supports both inline and modular installation configurations, enabling straightforward retrofits in existing systems or scalable deployments for new lines. With a G1/4 port and Rc1/8 gauge port, it integrates easily with standard piping and instrumentation, reducing installation time and risk. The push-to-lock knob adds security against unintended adjustments in busy environments, helping maintain setpoint integrity over time.
This Excelon regulator provides an outlet pressure adjustment of 0.3 to 10 bar and a maximum inlet pressure of 20 bar, with a relieving design to vent excess downstream pressure when the system is dead-ended. This combination ensures stable operating pressure for downstream equipment, reduces cycle variability, and protects components from overpressure in automated lines.
Yes. The unit uses a die-cast aluminium body, zinc bonnet, and nitrile elastomer seals, with an operating temperature range of -34 to 80 °C (-29 to 176 °F). This construction provides durability in typical automation and manufacturing settings, while maintaining reliable regulation and response across a wide ambient span.
The regulator features a dedicated Rc1/8 gauge port, allowing you to add a pressure gauge for real-time monitoring without compromising the regulator’s performance. This capability is especially valuable in tightly controlled processes where visual confirmation of downstream pressure enhances safety, quality control, and maintenance planning.
The design emphasizes stable setpoints through a tamper-resistant knob and robust materials, reducing drift and unauthorized adjustments. Inline/modular installation simplifies calibration and retrofit work, minimizing downtime. For ROI, expect lower energy waste due to precise pressure control, fewer unplanned shutdowns, and longer service intervals due to durable components suitable for continuous operation.
