IMI Norgren R73G-3GK-RSN Excelon Regulator - Relieving
Part Number: R73G-3GK-RSN
Quick Summary
The R73G-3GK-RSN Excelon pressure regulator provides precise downstream control for compressed air systems in manufacturing. Fluctuating downstream pressure can cause tool wear, inconsistent performance, and energy waste; this regulator delivers steady regulation with a balanced valve design. Note: Specific certifications such as CE, SIL, or IP ratings are not listed for this exact unit, but the Excelon family is engineered for safe industrial use and compatible with common compliance practices, including tamper-resistant adjustment. With inline or modular installation, robust construction, and Rc1/8 gauge port options, it integrates smoothly into existing pneumatic circuits, delivering reliability and cost savings in industrial automation environments.

Balanced valve design provides steady downstream pressure, reducing cycle-time variability and component wear. This translates to longer tool life and fewer unplanned downtime events in high-throughput production lines. The Excelon regulator supports inline or modular installation, with compatible G3/8 ports and Rc1/8 gauge connections for quick integration into existing pneumatic circuits. Relieving functionality protects downstream circuitry by reducing pressure if the system becomes dead-ended, limiting surge risks and protecting actuators. This contributes to safer startup and better control in automated handling and clamping operations. The unit features a push-to-lock adjusting knob with a tamper-resistant accessory, helping preserve setpoints in busy maintenance windows and multi-user environments. Durable diecast aluminium body, acetal knob, and nitrile elastomer seals ensure long service life in harsh industrial environments. With a flow capability of 60 dm3/sec and a maximum inlet of 20 bar, the regulator maintains consistent performance under demanding loads. Inline and modular installation support flexible system design, enabling rapid customization and scalable automation in assembly lines. Accessory and mounting options, including Excelon 73/74 modular system compatibility, simplify retrofit and maintenance workflows for engineers and technicians.

FAQs
To install the R73G-3GK-RSN in an existing Excelon modular system, connect the G3/8 port to the supply line and the Rc1/8 gauge port to the monitoring gauge or sensor loop. The unit supports inline or modular configurations and is compatible with common Excelon accessories such as the T73T-3GA-P1N shut-off valve and Quikmount adapters, enabling rapid retrofits without extensive re-piping.
The regulator provides an adjustable outlet range of 0.7 to 17 bar with a maximum inlet pressure of 20 bar. It features a G3/8 port size and Rc1/8 gauge port, designed for compressed air. The balanced valve design ensures stable regulation under varying load demands, supporting reliable performance in automated machinery and tooling applications.
Yes, for many automation lines. With a flow capacity of 60 dm3/sec (127 scfm) and a robust diecast aluminium body, the R73G-3GK-RSN maintains consistent downstream pressure even under fluctuating demand. The relieving option protects downstream components during dead-end conditions, while the tamper-resistant knob helps maintain setpoints in busy production environments.
The provided data does not list specific certifications such as CE, SIL, or IP for this exact unit. However, the Excelon family is designed for safe industrial use, with features like a relievin g model and tamper-resistant adjustment to support compliant and safe operation within typical pneumatic systems and control architectures.
Maintenance for the R73G-3GK-RSN can be supported with the service kit R73G-KITR, designed to simplify periodic maintenance and reduce downtime. For ongoing reliability, pair the regulator with compatible mounting and porting accessories such as 4316-52 porting blocks and Quikclamp kits to ensure secure, vibration-resistant installations in rugged environments.
