R73G-3AT-RMN

Quick Summary

Norgren R73G-3AT-RMN pressure regulator is designed to deliver precise compressed air control for automated manufacturing and process lines. Engineers often battle pressure drift, dead-ended relief, and inconsistent downstream performance that disrupts tooling and cycle times. This Excelon regulator features balanced valve design, inline or modular installation, and a push-to-lock adjusting knob for tamper resistance—delivering stable outlet pressure and reduced set-point drift. The unit supports standard relieving to protect downstream circuits when a system is dead-ended, improving safety and uptime. CE compliance is standard, and the design is compatible with SIL-rated control schemes in configured installations, with flexible mounting options including inline, neck mount, and Quikmount accessories. These attributes translate to lower maintenance, fewer part substitutions, and longer equipment life.

Inline or modular installation simplifies system layout and reduces panel footprint, enabling retrofits without costly piping changes. This flexibility speeds commissioning in new lines, and supports both in-line and modular drop-in configurations for control panels. Balanced valve design minimizes pressure overshoot during demand fluctuations, delivering stable outlet pressure and improved tool response, which translates into higher throughput and reduced scrap in high-speed production. Relieving capability protects downstream circuits when the system is dead-ended, reducing risk of equipment damage and enabling safer pressure decay in circuits with long piping runs. The push-to-lock adjusting knob, paired with a tamper-resistant accessory, helps maintain calibration in harsh environments and minimizes operator-initiated set-point drift. Diecast aluminium body, zinc-plated knob, and nitrile elastomer seals deliver robust durability in dirty conditions, extending service life and reducing maintenance intervals. With a 20 bar max inlet and 0.3–10 bar adjustable outlet flow of 60 dm3/sec (127 scfm), the unit accommodates diverse automation needs while remaining compact enough to fit tight manifolds. Compatibility with Quikmount, neck mounting brackets, and other mounting accessories provides versatile installation options for inline manifolds, pneumatic cabinets, and control panels, simplifying upgrades and replacements.

FAQs

Yes. The R73G-3AT-RMN supports in-line installation and modular mounting configurations. With a 3/8" PTF port and 1/4" gauge port, it fits common pneumatic manifolds and control panels, while compatible mounting accessories such as Quikmount and neck brackets simplify retrofits without extensive re-piping.
Key specs include a maximum inlet pressure of 20 bar, an adjustable outlet range of 0.3 to 10 bar (4 to 145 psi), a flow capacity of 60 dm3/sec (127 scfm), and a relief-enabled regulator design. The device uses a 3/8" PTF port with a 1/4" gauge port and a T-bar adjustment for precise tuning.
Yes. The Excelon R73G-3AT-RMN is a relieving model, designed to reduce downstream pressure when the system is dead-ended. This protects downstream components, minimizes overshoot, and supports safer shutdown procedures in lines that may become isolated or temporarily unloaded.
Several options support versatile installation, including Quikmount pipe adapters (4315-02), Neck Mounting Bracket (4461-50), Tamper Resistant Cover and Wire (4455-51), Mounting Nut (5191-88), Quikclamp (4314-51), and Quikclamp with wall mounting bracket (4314-52), plus the 'Universal' Bracket (4424-50). These enable inline manifolds, cabinet mounting, or wall-mounted configurations.
Industrial automation, packaging lines, robotics, and general pneumatics benefit from its precise pressure control, inline or modular installation, and dead-end relief capability. This makes it suitable for general purpose air line regulation in manufacturing environments requiring reliable, tamper-resistant adjustment and robust materials.
