Norgren R74G-4GT-RSN Excelon regulator - without gauge
Part Number: R74G-4GT-RSN
Quick Summary
R74G-4GT-RSN is a compact Excelon regulator that delivers precise pressure control for general pneumatic systems. Many OEM lines struggle with pressure drift and downtime when systems dead-end or fluctuate, impacting cycle times and productivity. While commonly aligned with CE-compliant practices and available in IP-rated configurations for harsh factory environments, this regulator is designed for inline or modular installation in demanding environments. The combination of balanced valve technology and easy T-bar adjustment reduces commissioning time and provides predictable actuation. For automation, robotics tooling, and versatile plant air networks, it delivers reliable, scalable pressure control with minimal footprint.

FAQs
The R74G-4GT-RSN supports inline and modular installation within the Excelon family, enabling flexible deployment on existing lines or new assemblies. It is compatible with common mounting accessories such as the Universal bracket and Quikclamp options, which simplify retrofits and reduce overall installation time.
Key specs include medium as compressed air, port size G1/2, gauge port Rc1/8, adjustment via T-bar, maximum inlet pressure of 20 bar, outlet adjustment from 0.7 to 17 bar, relieving operation, and a flow rate of 105 dm3/sec. Operating temperature ranges from -34 to 80 °C, with body and bonnet in die-cast aluminium and nitrile elastomers for seals.
Yes. The Excelon R74G-4GT-RSN includes relieving capability to reduce downstream pressure when the system becomes dead-ended, protecting downstream components and reducing risk of overpressure, pulsations, and potential line faults in automation cells.
For maintenance and compatibility, use the R74G-KITR service kit. Accessories such as T74T-4GA-P1N (Excelon modular shut-off valve), 4316-52 porting block, and mounting options like the 4324-50 Universal bracket and other Quikclamp variants simplify installation and service life.
The R74G-4GT-RSN delivers predictable pressure control, reducing abnormalities that cause downtime and waste. Easy field adjustment minimizes calibration time, modular installation speeds up commissioning, and robust materials extend service life, lowering total cost of ownership in general pneumatic systems and robotics applications.
