Norgren R73G-3GK-NMN Excelon Regulator - 0.3-10 bar
Part Number: R73G-3GK-NMN
Quick Summary
Norgren R73G-3GK-NMN Excelon pressure regulator provides precise inline control of compressed air for automation systems. Many engineers struggle with drift from unsecured adjustments; this unit’s push-to-lock knob and tamper-resistant accessory prevent unauthorized changes. Certification details aren’t listed in the data; verify CE, SIL or IP ratings on the datasheet to confirm compliance. Designed for inline or modular installation, it supports compact layouts and easy maintenance across automation lines. With a balanced valve design and a 0.3–10 bar range, it delivers stable output under varying loads. For purchasing teams, this translates to predictable performance, reduced maintenance calls, and lower life-cycle cost.

Excelon design enables in-line or modular installation, reducing panel space and simplifying retrofits on crowded machines. This flexibility accelerates commissioning, lowers installation time, and makes future upgrades straightforward. Compatible with compact control panels and modular valve systems, it supports scalable automation architectures without sacrificing access for service or diagnostics. A balanced valve design provides stable pressure control across varying flow demands, minimizing pressure bounce and actuator chatter. The predictable outlet pressure improves repeatability of pneumatic cycles and extends seal life in actuators, making it ideal for precision gripper actuation and pick-and-place lines where consistency matters. Push to lock adjusting knob with tamper-resistant accessory secures setpoints in busy environments, reducing unplanned changes and drift during shifts. Tamper protection lowers the risk of process variation and downtime while compatibility with 4455-51 tamper-resistant cover and wire extension simplifies upgrades and security compliance. The G3/8 port size with Rc1/8 gauge port enables straightforward piping and test points, while the non-relieving design maintains steady downstream pressure. A 20 bar maximum inlet pressure and 0.3–10 bar (4–145 psi) adjustable outlet support reliable actuator control across applications. With a flow capacity of 60 dm3/sec (127 scfm), the regulator suits mid-scale pneumatic circuits without throttling. Durable diecast aluminium body, zinc bonnet, acetal resin knob, and nitrile rubber elastomers deliver robust performance in factory environments. The Excelon R73G series supports inline and modular configurations and is compatible with service kits like R73G-KITR for efficient maintenance and reduced life-cycle costs.

FAQs
The R73G-3GK-NMN supports in-line or modular installation, enabling flexible mounting in tight control panels and on machine frames. This provides faster commissioning and easier future upgrades, with compatibility to Excelon modular components and standard G3/8 piping. It’s well-suited for automation lines that require compact footprints and scalable configurations without compromising service access.
The balanced valve design delivers tighter regulation and reduced pulsations, improving actuator response and system stability during fluctuating demand. Practically, this means steadier speeds for cylinders, fewer pressure spikes, and extended seal life in actuators—benefiting precision tasks like gripper operation and repeatable pick-and-place cycles.
Yes, the regulator is rated for a maximum inlet pressure of 20 bar and provides a non-relieving outlet. This ensures consistent downstream pressure without a built-in relief path, so system designers must account for adequate relief or safeties in the overall pneumatic circuit. The adjustable outlet range is 0.3 to 10 bar (4–145 psi) for precise control.
Certification details are not listed in this dataset. To confirm CE, SIL, IP or other standards, review the datasheet linked in the Downloads section (Datasheet PDF) or contact Norgren support. Verification on the datasheet ensures alignment with your regulatory needs and project requirements.
Maintenance is streamlined by the availability of a dedicated service kit (R73G-KITR) and compatible tamper-resistant accessories (4455-51). Cooler downtime, longer mean time between service, and more predictable performance contribute to lower lifecycle costs. The robust Excelon design supports longer service intervals in mid-scale pneumatic networks, improving overall uptime and return on investment.
