Norgren R72G-2AK-RCN Excelon Regulator - 0.3-2 bar Relieving
Part Number: R72G-2AK-RCN
Quick Summary
Norgren R72G-2AK-RCN Excelon regulator provides precise pressure control for compressed air systems in automation and manufacturing. When downstream pressure drifts or a system dead-ends, operators face wasted energy, erratic actuations, and unplanned downtime. The Excelon line is CE compliant and designed for reliable operation across -34 to 65 °C with a robust zinc diecast body and tamper-resistant knob, ensuring longevity in harsh environments. For engineers and procurement teams, this combination translates to consistent outlet pressure, reduced setpoint drift, and seamless integration with inline or modular installations, driving reliability and cost efficiency in pneumatic production lines.

FAQs
The R72G-2AK-RCN Excelon regulator is designed for inline or modular installation using 1/4" PTF ports and a 1/8" PTF gauge port. It supports pressures up to 20 bar and delivers adjustable outlet pressure from 0.3 to 2 bar. This combination enables straightforward retrofits into existing piping or new automation circuits without special adapters.
The regulator maintains a tight, repeatable setpoint across the specified range, minimizing pressure drift under varying load conditions. The balanced valve design reduces overshoot and rapid cycling, improving actuator response times and reducing energy waste in pneumatic tools and conveyors.
Yes. The Excelon R72G-2AK-RCN is built for reliable operation across -34 to 65 °C, with a zinc pressure-diecast body and acetal bonnet. Its relieving feature protects downstream systems, while the tamper-resistant knob helps maintain process integrity in busy production floors and controlled environments.
The Excelon regulator family is designed to meet common European safety and performance standards, with CE conformance to support European market requirements. This ensures compatibility with regulated automation environments and helps simplify compliance documentation for projects and audits.
By delivering stable outlet pressure and reducing setpoint drift, the R72G-2AK-RCN minimizes downtime and improves cycle consistency. The tamper-resistant knob reduces risk of unauthorized changes, lowering maintenance overhead and support calls, while the durable construction decreases replacement costs in high-usage lines.
