Norgren T74T-6AA-P1N Shut-off Valve - Excelon 3/2 Modular System
Part Number: T74T-6AA-P1N
Quick Summary
T74T-6AA-P1N is a compact Excelon 3/2 shut-off valve for inline pneumatic control in automated production lines. Engineers often struggle with downtime and misoperation when integrating modular valves into existing manifolds, leading to project delays and higher maintenance costs. Key certifications to verify include CE marking, SIL safety compatibility, and IP-rated enclosure options—check the datasheet for availability and options for this variant. By enabling inline or modular installation with other Excelon products, this valve reduces installation time, simplifies spare parts management, and boosts line uptime, aligning with efficiency targets in automated manufacturing and process control. This approach also supports broader benefits in industrial automation and streamlined procurement across valve families.

FAQs
Yes. The T74T-6AA-P1N uses a 3/4 inch PTF port and is designed for both inline installation and modular stacking with other Excelon components, enabling compact manifolds and straightforward integration into existing pneumatic circuits. Follow proper thread sealing practices and confirm that supporting components are rated for your system pressure to prevent leaks.
Maximum inlet pressure is 17 bar and operating temperature ranges from -34 to 65 °C (-30 to 149 °F). This makes the valve suitable for typical factory compressed air networks while maintaining performance in cool to warm environments. If service conditions exceed these limits, consult the datasheet for elastomer options and recommended replacements.
Yes, the T74T-6AA-P1N is compatible with inline and modular Excelon configurations, allowing rapid scaling of control logic without redesigning piping. Modular installation reduces part count, speeds up commissioning, and simplifies maintenance by keeping a consistent valve family across the line, which is especially beneficial in packaging and automotive assembly environments.
Nitrile rubber seals offer good compatibility with clean, dry compressed air and are suitable for most standard environments. Monitor for ozone exposure, high heat, or oil presence that can shorten seal life. If your service conditions exceed the elastomer’s tolerance, consider alternative materials per the datasheet and schedule periodic seal inspections during routine maintenance.
