Norgren R73G-2AK-RSG Pressure Regulator - Excelon Relieving
Part Number: R73G-2AK-RSG
Quick Summary
Norgren R73G-2AK-RSG pressure regulator is designed to deliver precise downstream pressure control for compressed air systems in automated manufacturing environments. Fluctuating supply pressure can cause erratic actuator performance and increased energy use, leading to inconsistent process cycles and higher operating costs. This Excelon regulator meets common industry standards and is available in configurations that support CE compliance, SIL safety concepts, and IP-rated enclosures when specified, ensuring safe, reliable operation in harsh environments. With inline or modular installation, a gauge port, and a tamper-resistant knob option, it offers fast retrofit potential and predictable performance across robotics, tooling, and automated assembly lines.

FAQs
The R73G-2AK-RSG supports both inline and modular installation, enabling flexible integration into new or existing pneumatic lines. It uses 1/4" PTF ports with a gauge port for monitoring and is compatible with mounting accessories such as Quikmount and Quikclamp variants to simplify panel or wall mounting and reduce install time.
Key specs include a maximum inlet pressure of 20 bar, an adjustable outlet range of 0.7 to 17 bar (10 to 247 psi), and a flow rating of 60 dm3/sec (127 scfm). It is a relieving type regulator designed for compressed air and features 1/4" PTF ports for both inlet and gauge connections.
Yes. The regulator is a relieving model, designed to reduce downstream pressure when a system is dead-ended, protecting downstream components and reducing the risk of overpressure during fault or maintenance conditions.
Maintenance can be supported with the R73G-KITR service kit, which provides replacement parts and guides for routine servicing. The tamper-resistant knob option enhances safety during adjustments, and the regulator's modular design facilitates field service and component replacements without complete disassembly.
By delivering stable downstream pressure despite supply fluctuations, the regulator minimizes actuator cycling variability and wasted air, improving cycle accuracy and reducing energy consumption. Its inline/modular installation reduces retrofit time, and durable construction lowers maintenance costs, supporting longer service intervals in high-volume production environments.
