Norgren R74G-4AK-NMN Pressure Regulator - 0.3-10 bar
Part Number: R74G-4AK-NMN
Quick Summary
Norgren R74G-4AK-NMN pressure regulator precisely controls compressed air pressure for automation and packaging lines. Common challenges include setpoint drift, dead-ended relief, and awkward inline mounting that disrupt workflow. This Excelon design supports inline or modular installation, a balanced valve for steady downstream pressure, and a push-to-lock knob with tamper-resistant options to prevent tampering in shared environments. The design aligns with standard industry certifications such as CE compliance and IP-rated configurations where applicable. With a 1/2" PTF port, 0.3–10 bar outlet range, and a robust diecast aluminium body, it delivers reliable performance, reduces waste, and simplifies maintenance in demanding pneumatic systems.

FAQs
The R74G-4AK-NMN supports both inline and modular installation using 1/2" PTF ports with a 1/4" gauge port for monitoring. It is compatible with Norgren mounting accessories such as Quikmount pipe adapters and Quikclamp systems, enabling quick retrofits and clean line layouts in new builds.
Key specs include a maximum inlet pressure of 20 bar and an adjustable outlet pressure range of 0.3 to 10 bar. The regulator provides a flow of 105 dm3/s, operates from -34 to 80 °C, and is non-relieving, ensuring downstream pressure stability for sensitive actuators.
Yes. Its balanced valve design delivers stable downstream pressure, even under fluctuating supply conditions, and the non-relieving configuration provides consistent performance in dead-ended sections. The rugged diecast aluminium body and nitrile seals support reliable operation in busy automation environments.
This model is designed to align with common industry certifications; verify the datasheet for exact CE compliance and IP-related options based on configuration. If your application requires SIL or other safety-specific certifications, consult the datasheet or reach out for a configuration that meets those requirements.
The regulator’s precision control reduces pressure-related wear on downstream actuators, lowering maintenance and replacement costs. Tamper-resistant knobs minimize drift caused by unauthorized adjustments, and modular compatibility with mounting systems shortens downtime during replacements or upgrades, improving overall line uptime and process reliability.
