Norgren T68H-8GB-B2N Valve - 3/2 Shut-off, G1 Port
Part Number: T68H-8GB-B2N
Quick Summary
The Norgren T68H-8GB-B2N valve is a compact 3/2 shut-off for pneumatic control in automation. Engineers often contend with leaks and difficult actuation in tight-space installations, leading to downtime and maintenance overhead. Although the Olympian Plus family promotes robust performance, verify certifications such as CE marking, IP ratings, and SIL on regional datasheets to meet regulatory needs. Designed for a G1 port and easy installation, it delivers reliable control with a 1/4 inch exhaust, helping your production lines achieve higher uptime and lower lifecycle costs. For procurement, this translates to improved component standardization and faster maintenance planning within pneumatic systems.

FAQs
Install the T68H-8GB-B2N by aligning the G1 threaded port with your manifold inlet, secure the valve to the rail or panel, connect the compressed air supply, and attach the 1/4" exhaust as specified. Ensure the inlet pressure does not exceed 17 bar and verify the T handle can be locked in the desired state during setup and testing.
Key specs include a 3/2 valve operation, G1 port, maximum inlet pressure of 17 bar, flow capacity of 451 dm3/sec (956 scfm), operating temperature range of -20 to 80 °C, and an aluminium body with nitrile elastomer seals. The actuator is a T handle, and the unit weighs about 0.988 kg, suitable for mid to high-speed pneumatic control.
Yes, for many packaging lines requiring reliable, fast actuation and compact footprints. The 3/2 configuration supports straightforward on/off control, while the 17 bar rating and 956 scfm flow enable quick response. The lockable open/closed feature enhances safety during changeovers, and the light aluminium body supports repeated cycling in tight spaces.
The provided data focuses on the Olympian Plus family and essential specifications but does not list explicit certifications such as CE, IP, or SIL. For global deployments, verify regional compliance with the supplier datasheets and ensure CE marking, IP protection, and any required SIL ratings are met for your specific application.
Maintenance benefits come from the valve’s robust aluminium body and nitrile seals, reducing corrosion risk and leakage. The lockable mechanism simplifies safe servicing, while its compact size and plug-in design shorten installation and changeover times. Over time, this translates to lower downtime, standardized spare parts, and a clearer maintenance strategy across multiple lines.
