Norgren T68H-AGB-B2N Shut-off Valve - G1-1/4 Port
Part Number: T68H-AGB-B2N
Quick Summary
Norgren T68H-AGB-B2N shut-off valve is a compact 3/2 plug-in system that delivers precise compressed-air control for automation lines. Operators face downtime from leaks, misalignment, and difficult changeovers; this valve's lockable open/closed positions and clear exhaust path help minimize those issues. Although the provided data doesn't list certifications, this valve type typically aligns with CE marking and SIL safety practices, and IP-rated enclosures are common in harsher environments; verify the applicable certifications for your project. Designed around an aluminium body and nitrile elastomer seals, it balances durability with lightweight handling, while its 1/4" exhaust and compact footprint simplify panel integration and service.

FAQs
When installing the T68H-AGB-B2N, plan for the G1-1/4 port size and the 3/2 valve configuration to ensure correct air routing. Use the plug-in mounting for quick commissioning, verify exhaust routing options, and provide secure mounting to prevent vibration or misalignment. Leave adequate space for access to the lockable actuation and exhaust paths for maintenance.
Key specs include a flow rating of 451 dm3/sec (956 scfm) and a maximum inlet pressure of 17 bar, supporting high-demand actuators. Operating temperature spans -20 to 80 °C, enabling stable performance in diverse environments. The 3/2 valve operation and G1-1/4 port are critical for reliable actuation and exhaust management in demanding cycles.
Yes, within its stated temperature range (-20 to 80 °C) and aluminium body with nitrile elastomer seals, the valve is designed for robust plant environments. For outdoor or particularly harsh settings, confirm IP protection requirements and ensure enclosure choices align with site conditions. Always verify environmental ratings with your supplier for your exact application.
Check for CE marking and applicable safety standards for your region, along with any SIL compatibility needs for your safety instrumented systems. Depending on the installation, confirm IP ratings for environmental exposure and ensure the valve integration aligns with your company’s maintenance and reliability programs. Always request the latest certifications from the distributor or manufacturer.
The combination of a lockable actuation, durable aluminium body, and Buna/Nitrile seals reduces unplanned downtime and maintenance intervals. Its compact plug-in design speeds commissioning, while its high-flow capability supports larger actuator banks. Over time, the result is lower lifecycle costs, streamlined maintenance, and more predictable production throughput.
