Norgren T68H-4GB-B2N 3/2 Plug-in Shut-off Valve - G1/2
Part Number: T68H-4GB-B2N
Quick Summary
The T68H-4GB-B2N is a 3/2 plug-in shut-off valve for compressed air systems. This compact unit delivers reliable on/off control of pneumatic actuators in automation lines, helping to reduce cycle times and improve overall line reliability. A common challenge is unintended actuation during maintenance, which this valve mitigates with a lockable open or closed position. Certification notes: CE/SIL/IP status for this unit are not specified in the data; verify compliance with regional standards during procurement. In practice, the Olympian Plus design combines a robust aluminium body with nitrile elastomer seals, enabling easy integration with OEM machinery and service-friendly maintenance and replacement workflows.
