Norgren R72G-3GK-RCN Excelon Regulator - G3/8 0.3-2 bar
Part Number: R72G-3GK-RCN
Quick Summary
Norgren R72G-3GK-RCN Excelon regulator provides precise pressure control for compressed air systems used in automation and packaging lines. Engineers often struggle with downstream pressure drift when lines are dead-ended or misconfigured. This Excelon family carries CE marking and general industrial compliance, with SIL-capable and IP-rated options available on select variants to meet demanding environments. Inline or modular installation is supported, enabling flexible layouts without compromising performance. The knob-adjustment design simplifies tuning while maintaining tamper resistance for safer operations. For machine builders and maintenance teams, the combination of reliable regulation, compact footprint, and straightforward service translates into faster startups and lower lifecycle costs. Use the R72G-3GK-RCN where consistent output pressure and easy field adjustments matter.

FAQs
The R72G-3GK-RCN is designed for both inline and modular installation on G3/8 ports, allowing flexible placement across machines and panels. Its compact form factor plus compatible porting simplifies retrofits and new builds alike, enabling quick integration with minimal additional components and reduced lead times.
A balanced valve design minimizes calibration shifts caused by supply pressure fluctuations, delivering a steadier downstream pressure. In practice this translates to more consistent actuator speed and position, fewer over- or under-pressurized cycles, and improved process repeatability in automation and packaging lines.
Yes. The R72G-3GK-RCN provides adjustable 0.3–2 bar output with reliever capability and a 20 bar inlet rating, making it well-suited for packaging equipment where stable, low-pressure regulation and quick re-tuning are needed to accommodate different product handling tasks.
The Excelon regulator family typically aligns with CE marking and general industrial safety standards. For critical or harsh environments, select variants offer SIL-capable configurations and robust IP-rated housings to meet higher safety and protection requirements. Always verify the exact variant’s certification notes for your application.
Routine checks focus on knob function, port cleanliness, and sealing elements made from nitrile elastomers. Benefits include longer service intervals due to durable materials, reduced downtime from easier field adjustments, and predictable operating costs through stable downstream pressure and fewer regulator-related faults.
