Norgren T68H-BGB-B2N 3/2 Shut-off Valve - G1-1/2 Port
Part Number: T68H-BGB-B2N
Quick Summary
Norgren T68H-BGB-B2N is a compact 3/2 shut-off valve designed for high-reliability pneumatic control in automated production lines. Engineers often face leaks, slow actuation, and maintenance challenges in tight spaces that disrupt line throughput. This valve's Olympian Plus construction uses an aluminium body and nitrile elastomer seals, with a lockable open or closed position for safe service. While certification details vary by region, users should verify CE compliance, SIL readiness, and IP protection in the datasheet. Built for durability and fast installation, it supports predictable cycle times, lower downtime, and improved reliability across packaging, machine tending, and automated assembly.

FAQs
For best results, mount the valve in a standard manifold or panel with direct inlet/outlet connections and an accessible lockable actuation. Use the 1/4" threaded exhaust to route air away from sensitive components. Ensure compatibility with G1-1/2 port sizing and maintain clear airflow paths to avoid pressure drop that could affect quick cycling.
The 3/2 arrangement provides a dedicated supply, exhaust, and control path, enabling rapid, clean cylinder actuation and reliable venting. Combined with a 17 bar maximum inlet pressure and a high flow rate (451 dm3/sec), it supports fast response times and consistent cylinder travel in automated lines, reducing cycle times and improving throughput.
Yes, the valve is designed for broad industrial environments, with an operating range of -20 to 80 °C. The aluminium body and nitrile elastomer seals are chosen for durability and chemical compatibility with standard compressed air systems, contributing to stable performance in environments such as paint booths, automated assembly, and packaging lines.
Confirm certifications in the product datasheet and regional approvals. Key considerations typically include CE compliance, SIL readiness, and IP ratings relevant to your installation. Always check the exact model configuration and regional requirements with the datasheet to ensure full compliance for your application.
The combination of a lockable actuation feature, robust aluminium body, and nitrile seals reduces maintenance downtime and leak potential, improving uptime and cycle consistency. Its compact footprint and reliable actuation support easier installation and longer service intervals, contributing to lower total cost of ownership in packaging, machine tending, and automated assembly lines.
