Norgren R72G-2GK-RCN Excelon pressure regulator - Relieving
Part Number: R72G-2GK-RCN
Quick Summary
The Norgren R72G-2GK-RCN Excelon regulator controls compressed air pressure for automated manufacturing systems. Fluctuating downstream pressure and dead-end lines can cause costly downtime and inconsistent actuation. While specific certifications aren’t listed in the data, Excelon regulators are commonly designed to meet industry safety and quality expectations, including CE compliance and robust construction for challenging environments. This combination of inline installation capability, 0.3–2 bar outlet adjustment, and tamper-resistant adjustment knob delivers reliable control and easier integration into existing pneumatic circuits, supporting improved uptime and operational efficiency.

FAQs
Install the R72G-2GK-RCN in-line or as part of a modular assembly using the G1/4 port. Ensure the system is depressurized, then connect supply and downstream lines, verify gauge port accessibility Rc1/8 for monitoring, and calibrate outlet pressure to 0.3–2 bar using the knob with the push-to-lock feature to prevent unintended adjustments.
Expect a maximum inlet pressure of 20 bar, outlet pressure adjustable from 0.3 to 2 bar (4–29 psi), relieving operation, flow capacity around 33 dm3/sec (70 scfm), and a temperature range of -34 to 65 °C. The device is designed for compressed air in-line installation with a gauge port for monitoring.
Yes. The Excelon design supports inline installation, relieves downstream pressure to prevent overpressure in dead-end sections, and provides stable pressure regulation. With a 0.3–2 bar setpoint and reliable knob adjustment, it maintains consistent actuator performance even in high-cycle environments.
Specific certification details aren’t listed in the provided data. Generally, regulators in this class align with industry safety and quality expectations, including CE compliance. For definitive certification status, consult the datasheet or contact the supplier for the exact regulatory marks and testing reports.
The regulator reduces downtime by stabilizing downstream pressure, minimizes actuator misfires, and lowers maintenance due to tamper-resistant adjustment. Combined with flexible installation and durable construction, the R72G-2GK-RCN can shorten cycle times and extend component life, driving measurable uptime and operating cost reductions.
