Norgren R74G-3GK-RMN Pressure Regulator - 0.3-10 bar
Part Number: R74G-3GK-RMN
Quick Summary
Norgren R74G-3GK-RMN pressure regulator delivers precise upstream control for compact pneumatic systems in manufacturing and packaging lines. Engineers often struggle with drift, downstream pressure variation, and tool wear when regulators mismanage supply, leading to inconsistent cycles and higher maintenance. While the datasheet does not specify formal certifications, CE conformity, SIL safety considerations, and appropriate IP protection are common expectations for critical equipment in industrial settings. The Excelon design addresses these concerns with in-line or modular installation, a balanced valve for stable regulation, and a relieving option that protects downstream when the system is dead-ended. This combination supports lean manufacturing by delivering reliable pressure control, fewer stoppages, and easier compliance reporting across multiple lines.

FAQs
Yes. The R74G-3GK-RMN is designed for both inline and modular installation, enabling straightforward integration into current pneumatic networks. The compact dimensions (74 mm height, 170 mm length, 80 mm width) and robust die-cast aluminum body support versatile mounting options, while compatibility with standard G3/8 ports and Rc1/8 gauge port simplifies integration with common components and sensors.
Key specifications include port size G3/8, gauge port Rc1/8, outlet pressure range 0.3–10 bar, maximum inlet pressure 20 bar, and a flow rate of 105 dm3/sec. Operating temperature is -34 to 80 °C, and the unit uses a knob for adjustment with a tamper-resistant option. It is a relieving regulator designed to protect downstream when dead-ended and is part of Norgren's Excelon line.
Ideal for automation cells, packaging lines, robotics, and general pneumatic control, the regulator provides stable downstream pressure through a balanced valve design, reducing pulsations and tool wear. The relieving feature protects sensitive equipment during dead-end conditions, while inline/modular installation supports scalable automation and quick line changes, contributing to higher throughput and reduced maintenance.
Check the product datasheet and local regulations to confirm CE conformity, SIL safety considerations, and appropriate IP protection for your environment. While this data set highlights performance features, regulatory compliance often depends on regional standards and the full documentation from the manufacturer. Always validate with the datasheet and your quality system before deployment.
Service options include using the R74G-KITR service kit for routine maintenance, and replacing wear parts such as seals and elastomers as needed. Access to CAD models, datasheets, and installation guides supports proper installation and ongoing reliability. Regular calibration checks and inerted filter strategies help sustain performance and reduce unplanned downtime.
