Norgren T73T-3AA-P1N Excelon 3/2 Valve - Lockable Closed
Part Number: T73T-3AA-P1N
Quick Summary
Norgren Excelon T73T-3AA-P1N is a compact 3/2 valve for precise compressed air shut-off. In demanding automation lines, stiction, drift, and leaks can slow cycles and inflate maintenance costs, but this design minimizes start-up resistance and provides reliable operation. Certifications and compliance are configuration-dependent; look for CE marking, SIL readiness, and IP-rated options in the datasheet to meet your safety and regulatory requirements. When paired with other Excelon modular components, it delivers scalable control while reducing assembly time. Targeted for inline or modular installation, it supports streamlined panel design and consistent performance across machines and lines.

FAQs
Begin by identifying the 3/8" PTF ports and ensuring a compatible piping layout. The Excelon design supports in-line installation or modular integration with other Excelon components. Use the threaded exhaust port for proper venting and secure mounting to a pre-defined bracket or panel. Verify torque specs and seal integrity, then test the circuit at a low pressure before full operation.
Key specs include a 3/2 valve operation with slide lever actuation, 3/8" PTF port size, maximum inlet pressure of 17 bar, flow rate of 131 dm3/s (278 scfm), operating temperature from -34 to 65 C, and zinc body with nitrile elastomer seals. The valve supports inline or modular configurations within the Excelon family.
Yes, its low-stiction actuation and lockable closed position help minimize cycle-to-cycle variability and leakage in medium-speed to high-speed packaging lines. The compact 3/2 design and 3/8" ports offer reliable shut-off, while the Excelon modular approach supports scalable integration as line throughput grows or configurations change.
Certification availability is configuration-dependent. Look for CE marking, SIL readiness, and IP-rated options in the datasheet and installation guide for your specific build. Consult the CAD and PDF datasheets to confirm which certifications accompany the chosen configuration and to ensure compliance with your regional requirements.
The lockable closed position reduces unintended leaks during maintenance, while low-stiction actuation lowers wear and energy losses over time. The modular Excelon ecosystem simplifies spares and upgrades, cutting downtime for repairs and improving panel scalability, which translates to lower total cost of ownership for pneumatic systems.
