Feature → Balanced valve design for optimum pressure control improves downstream stability and reduces system-wide pressure fluctuations, enabling tighter tolerances in automated assemblies. Business Impact → This translates to fewer malfunctions, lower scrap rates, and improved line throughput in high-volume production. Application → Best suited for general pneumatic circuits requiring consistent pressure delivery in compresses air networks. Feature → Inline or modular installation capability reduces integration time and simplifies retrofits in existing plants. Business Impact → Engineers can leverage space-saving layouts and quicker serviceability on crowded control panels. Application → Ideal for retrofit projects and new builds where space is at a premium. Feature → Push to lock adjusting knob with tamper resistant accessory enhances reliability and operator accountability. Business Impact → Minimizes accidental setting changes and reduces maintenance calls. Application → Critical in shared production lines and safety-conscious environments. Feature → G1/4 port and Rc1/8 gauge port support flexible piping and easy diagnostics. Business Impact → Streamlines installation, calibration, and gauge verification. Application → Common in compact control modules and Excelon 73/74 series configurations. Feature → Non-relieving operation with 0.7–17 bar output and 20 bar max inlet ensures predictable control under load. Business Impact → Improves repeatability and protects downstream actuators from pressure spikes. Application → Essential for precision pressurization and automation loops where strict pressure bands are required. Feature → Material choices (die-cast aluminium body, zinc bonnet, nitrile elastomers) deliver durability in harsh factory environments. Business Impact → Extends service life and reduces replacement cycles in vibration-prone areas. Application → Suitable for continuous duty in industrial air systems with demanding temperatures. Feature → Flow capacity of 60 dm3/sec (127 scfm) supports moderate to high-demand circuits. Business Impact → Maintains responsiveness in fast-paced lines and supports higher cycle rates. Application → Useful in applications with rapid pressure balancing and quick cycle times.

FAQs

Yes. The R73G-2GT-NSN is designed for inline or modular integration with Excelon 73/74 series accessories. It uses a G1/4 port and Rc1/8 gauge port, enabling seamless connection to compatible porting blocks (4316-52) and quikmount systems (4315-09). For best results, pair with T73T-2GA-P1N shut-off valves and the Quikclamp mounting options to simplify installation and service access in compact control panels.
The unit provides an outlet pressure adjustment range of 0.7 to 17 bar with a maximum inlet pressure of 20 bar. It is a non-relieving regulator, meaning it maintains set pressure without venting when the output side is under load. Ideal for stable pneumatic circuits where precise downstream pressure is required and venting is undesirable.
Yes, thanks to its balanced valve design and Excelon architecture, the R73G-2GT-NSN offers stable pressure control with reduced drift, which is beneficial for high-cycle automation lines. Its robust construction (diecast aluminium body and nitrile elastomers) supports reliable performance in vibration-prone environments, while the 0.7–17 bar range covers most general pneumatic actuation needs.
Certification details are not listed in the provided data. Please consult the official Norgren datasheet linked in the product downloads (Datasheet PDF, Installation Guide PDF) or contact the supplier to confirm CE marking, IP rating, and SIL suitability for your specific region and safety requirements.
The regulator features a push-to-lock adjusting knob with tamper-resistant options, reducing unintended changes and calibration drift. Its inline/modular installation simplifies servicing and part replacement, while durable materials (aluminium body, zinc bonnet, nitrile elastomers) extend service intervals. Together, these aspects reduce downtime, improve process stability, and lower total cost of ownership over the regulator’s life in automated systems.
