Norgren R73G-2AT-RSN Excelon regulator - Relieving
Part Number: R73G-2AT-RSN
Quick Summary
The R73G-2AT-RSN is a general purpose pressure regulator for compressed air systems. Engineers often wrestle with downstream pressure drift, space constraints, and costly calibration cycles. The Excelon design uses a balanced valve and a relieving function to protect downstream circuits. Inline or modular installation and a push-to-lock adjusting knob support fast, tamper-resistant commissioning. In many markets CE marking and standard safety norms accompany these regulators; check the datasheet for the exact certifications. Together these features deliver reliable performance, lower maintenance costs, and easier scalability in automation environments. Retailers and OEMs benefit from a compact 1/4" PTF footprint and broad operating range.

Balanced valve design delivers precise downstream pressure control, reducing fluctuation and wear on connected tools, which translates to longer tool life and fewer scrap cycles in high-cycle automation. In practice, this improves pneumatic circuit stability across production lines and minimizes rework due to pressure swings. Inline or modular installation options provide flexible deployment, enabling easy retrofits and scalable automation without costly system overhauls. Operators experience faster commissioning and fewer downtime events when expanding or reconfiguring lines. The relieving function protects downstream devices during dead-end conditions, reducing energy waste and potential component damage in peak-flow scenarios. Tamper-resistant adjustment with a push-to-lock knob prevents accidental setting changes, supporting compliance and reducing maintenance calls. A wide operating range (−34 to 80 °C) and robust materials ensure compatibility with diverse factory environments, delivering consistent performance with less maintenance. The 1/4" PTF ports and 60 dm3/s flow support efficient, high-throughput air regulation for tooling and automation assets. This combination of features is especially valuable for OEMs seeking predictable costs and extended service life.

FAQs
Yes. The regulator uses 1/4 inch PTF ports for both inlet and gauge connections, enabling straightforward integration into existing 1/4 inch pneumatic circuits. Its inline or modular mounting options simplify retrofits and new installations without custom adapters.
Key specs include a maximum inlet pressure of 20 bar, an adjustable downstream range of 0.7 to 17 bar (10 to 247 psi), and a rated flow of 60 dm3/s (127 scfm). The device is a relieving regulator, providing downstream relief when the system is dead-ended to protect components.
Yes. The Excelon regulator is designed for inline installation with a balanced valve that stabilizes pressure across cycles, improving cycle consistency and tool life in automated production lines. Its compact footprint and modular installation options support scalable automation without bulky hardware.
CE marking and adherence to common industrial safety norms are typical for this class of regulator, with exact certifications documented in the datasheet. Always verify the specific regulatory marks on the product packaging or datasheet to ensure compliance for your region and application.
Plan for periodic inspection of elastomer seals (Nitrile rubber) and the adjusting knob, which is zinc-plated steel, to prevent leakage and drift. The die-cast aluminium body and zinc bonnet offer durability on the factory floor, reducing replacement frequency. Regular checks of inlet pressure and outlet setpoint accuracy help sustain performance and ROI.
