Overview
The Norgren P74C-NAD-PPA is an Excelon® 74 series solenoid-operated control valve featuring a 3-port/2-position (3/2) configuration with spring return and integral lockout capability. This 24 VDC model operates from -20°F to 130°F (-30°C to 55°C) and provides reliable pneumatic system control in industrial applications. The valve’s modular design allows integration with Norgren Quikclamp® adapters for flexible piping configurations without requiring port threading.
