Overview
The Norgren R74G-6AK-RMG is a general-purpose pneumatic pressure regulator engineered for industrial air preparation applications. As part of Norgren’s Excelon modular system, this unit delivers precision pressure control with integrated pressure gauging. The regulator features a robust inlet pressure rating of 300 PSIG (21 Bar) and a maximum outlet pressure of 150 PSIG (10.3 Bar), making it suitable for demanding pneumatic systems requiring stable, filtered air.
