The compact aluminium body with nitrile elastomer seals reduces weight while delivering durable performance in harsh plant environments, translating to lower structural fatigue and longer service life. The 3/2 valve configuration with an unthreaded exhaust simplifies piping layouts and reduces leak paths, improving system reliability and reducing maintenance overhead in crowded valve manifolds. The T handle actuation that can be locked in open or closed positions enhances operator safety and process control, eliminating accidental actuation and improving line shutdown procedures. A high flow rating of 451 dm3/sec (956 scfm) supports faster cycle times, delivering tangible productivity gains on quickly actuated circuits and high-demand lines. Operating from -20 to 80 °C and up to 17 bar inlet pressure, the valve tolerates typical industrial environments while maintaining consistent performance. Compatibility with G1-1/4 piping and plug-in installation keeps replacement and manifold upgrades straightforward, supporting scalable automation strategies and reduced downtime during maintenance.

FAQs
Install using standard G1-1/4 piping with the valve mounted in a vertical or horizontal orientation as allowed by the designation. Connect the compressed air supply to the inlet port, attach the outlet to the downstream control line, and ensure the exhaust path is unobstructed or fitted with an appropriate silencer. Use the T handle for manual operation and engage the lockout feature during setup or maintenance to prevent unintended actuation. Verify seals and tighten fittings to manufacturer torque recommendations to avoid leaks.
The T68C-AGB-B2N supports a maximum inlet pressure of 17 bar and operates across a temperature range of -20 to 80 °C (-4 to 176 °F). This makes it suitable for typical industrial pneumatic circuits and tools exposed to varied climates and process conditions while maintaining reliable shut-off and actuation performance.
Yes, the 3/2 plug-in shut-off design with a robust aluminium body and nitrile elastomer seals is well-suited for moderate to high-cycle automation lines. Its flow rating of 451 dm3/s (956 scfm) supports rapid actuation, while the lockable open/closed positions help prevent accidental cycling during startup, maintenance, or safety-critical operations.
Certification details are model-specific and listed in the datasheet. When selecting this valve for regulated environments, verify CE compliance and any SIL- or IP-related classifications shown for your market. Always consult the latest installation guide or datasheet to confirm which certifications apply to your configuration and jurisdiction.
The lockable open/closed feature reduces accidental actuation and unplanned stoppages, contributing to lower downtime costs. The durable aluminium body and nitrile elastomer seals resist wear in harsh environments, decreasing maintenance intervals. Combined with straightforward G1-1/4 installation and a reliable 3/2 operation, users typically see improved line uptime and predictable performance, supporting a favorable total cost of ownership in automated pneumatic systems.
