Norgren R73G-3GT-RSN Excelon Regulator - Relieving
Part Number: R73G-3GT-RSN
Quick Summary
R73G-3GT-RSN pressure regulator provides precise downstream pressure control for compressed air systems in automation and manufacturing. Unstable pressure or dead-ended lines can cause tool chatter, inconsistent performance, and costly downtime. The Excelon design supports inline or modular installation with a balanced valve arrangement and standard relieving to protect downstream circuits, while the push-to-lock adjusting knob adds tamper resistance for safe operation. Typical industry approvals like CE compliance and compatibility with standard setpoints underpin reliable performance in harsh factory environments. By combining robust materials with a compact footprint, this regulator helps engineers meet efficiency targets and reduce maintenance costs across OEM installations and repairs.

Feature: Balanced valve design provides precise pressure control with minimal drift. Business impact: This translates to tighter setpoints and fewer fluctuations in downstream pressure, which reduces cycle times and tool wear in high-usage lines. Application: Use in automated assembly cells and inline production lines where consistent regulator performance is essential. Feature: Relieving capability allows downstream pressure relief when the system is dead-ended. Business impact: It protects sensitive downstream equipment from overpressure events, lowers energy loss, and simplifies safety compliance during maintenance. Application: Critical for long piping runs and systems with rapid valve closures in packaging, painting, or robotics stations. Feature: Push-to-lock adjusting knob with tamper-resistant accessory. Business impact: Prevents accidental changes, maintains stable settings in vibration-prone environments, and supports audit trails. Application: Installed in OEM control panels and machine bays exposed to shop floor conditions. Feature: Inline or modular installation offers flexible mounting options. Business impact: Reduces cabinet footprint, speeds retrofits, and eases scalability for growing lines. Application: Suitable for machine builders adding to existing lines or configuring new automation cells. Feature: Wide operating temperature range and robust materials. Business impact: Ensures reliable performance from cold rooms to heated clinics, lowering replacement cycles and maintenance costs. Application: Suits industrial automation in varied climates with diecast aluminium body and nitrile elastomer seals.

FAQs
The R73G-3GT-RSN fits standard G3/8 piping and Rc1/8 gauge ports. For inline mounting, attach the regulator directly to the service line; for modular installations, use compatible bracket assemblies. Ensure the outlet pressure range is set within 0.7–17 bar and verify seals, fittings, and torque per the datasheet to avoid drift.
Outlet pressure is adjustable from 0.7 to 17 bar with a maximum inlet pressure of 20 bar. Flow capacity is about 60 dm3/s (127 scfm). The G3/8 port size and Rc1/8 gauge port support typical OEM air circuits, enabling stable regulation across standard automation loads.
Yes. The unit uses a zinc-plated adjusting knob, a die-cast aluminium body, and nitrile elastomer seals, delivering resilience in vibration-prone manufacturing cells. The tamper-resistant knob helps prevent unwanted changes during operation, supporting consistent performance in dynamic environments.
This Excelon regulator is designed for industrial use with CE compliance, ensuring alignment with essential safety directives. For more advanced safety classifications like SIL or IP ratings, consult the full datasheet and your certification requirements to confirm suitability for your specific risk profile.
Relieving capability protects downstream components from overpressure, reducing downtime and maintenance costs. A balanced valve design minimizes drift, while the tamper-resistant knob reduces inadvertent setting changes, contributing to longer tool life and more predictable operation in OEM installations.
