FAQs
Install the R73G-3GK-NFN in a compact pneumatic loop using the G3/8 port and Rc1/8 gauge connection for monitoring. Take advantage of the inline or modular installation design to fit tightly on existing frames or modular panels, and consider the tamper-resistant accessory for environments where unintentional adjustments must be prevented.
The regulator provides an adjustable outlet range of 0.3 to 4 bar (4 to 58 psi) with a maximum inlet pressure of 20 bar. It is a non-relieving device, ensuring controlled behavior in fault conditions and improving safety and predictability in pneumatic circuits.
Yes. Its balanced valve design delivers stable pressure control, supporting consistent actuator performance in packaging and automation lines. The inline/modular installation capability simplifies integration into compact lines, while the 0.3–4 bar adjustment range accommodates typical packaging actuators and regulators used in modern manufacturing cells.
The data provided highlights safety-oriented features and standard industry design practices, including tamper-resistant options and robust materials. For regulatory compliance, verify regional requirements and supplier documentation (including CE-related expectations where applicable) with your procurement team or Norgren representative to ensure alignment with your specific regulatory regime.
Maintenance can be supported with the R73G-KITR service kit specific to the R73G range, along with replacement parts for the adjusting knob and elastomer seals. Regular checks on inlet pressure, outlet setting accuracy, and visual inspection of the gauge port should be part of a preventive maintenance plan to sustain performance and reduce downtime.
