Norgren T74T-4AA-P1N Excelon 3/2 valve - 1/2 inch PTF
Part Number: T74T-4AA-P1N
Quick Summary
Excelon 3/2 valve from Norgren provides compact shut-off control for automated lines. Engineers often struggle with inline installation, limited space, and inconsistent actuation feel; this valve offers low stiction and an optional modular fit. To support safe and compliant operations, look for CE marking and IP-rated variants, with SIL options available in broader Excelon families—verify the datasheet for your exact configuration. With inline or modular installation, 1/2 inch PTF porting, and a lockable closed position, this valve enables faster assembly, reduced downtime, and predictable performance across multiple production cells.

FAQs
The T74T-4AA-P1N supports both inline installation along a pneumatic line and modular installation with other Excelon products. This flexible mounting allows rapid integration into existing manifolds or new lines, simplifying retrofits and scalable automation projects in manufacturing environments.
The 3/2 valve design provides a straightforward open or closed state with a dedicated exhaust path. The lever actuation, combined with a lockable closed position, reduces the risk of unintended actuation during maintenance and improves repeatability of cylinder retraction, which is critical for fixture-based processes and packaging lines.
Operating temperature ranges from -34 to 65 °C (-30 to 149 °F), and the valve supports a maximum inlet pressure of 17 bar. The nominal flow is 133 dm3/sec (282 scfm), enabling reliable actuation of standard pneumatic cylinders while maintaining energy efficiency in typical industrial cycles.
The provided data highlights the Excelon series’ general suitability for industrial use and mentions common safety and compatibility considerations. Specific CE certification, IP rating, or SIL options for this exact model should be confirmed in the datasheet or by consulting Norgren support to ensure regulatory compliance for your application.
With a zinc body and nitrile elastomer seals, the valve is designed for durability in standard compressed air systems. Regular inspection of the exhaust port, seals, and actuation linkage helps maintain low stiction performance. Plan for standard spare parts and periodic testing in line with maintenance schedules to ensure consistent performance and reliability.
