Quick Summary

The Norgren T84T-3AA-B1N is a compact pneumatic 3/2 valve for fast shut-off in automated production lines. In crowded panels, bulky valve assemblies frustrate serviceability and drive downtime. The Excelon Plus family supports a flexible modular system with built-in tamper-proof options and rotating safety shut-off, enabling safer, faster maintenance. Across the Excelon Plus range, CE conformity and IP-rated variants are commonly specified in regional configurations, with potential SIL-rated options for safety-critical environments. This combination delivers space-efficient performance and reliable control, reducing maintenance cost while simplifying integration into modular pneumatic systems. Use with 3/8\" PTF ports and compatible mounting brackets to maximize efficiency in factory automation and packaging lines.
