FKX 9000

The FKX 9000 Triple Offset Valves valve design is recommended for industrial applications where large
bore valves handle hot steam or isolate parts of their plants and have high/low temperatures that prevent the
use of rubber lining elements.


Compared to ball valves, the Crane®FKX 9000 Triple Offset Valves is an affordable solution that requires less
structural support to ensure bubble tight shut-off. The result is a virtual zero leak rate even in high-pressure, high-temperature applications. Due to their quarter-turn movement for opening and closing, the valves are easy to automate and they can fulfill a quick closing time, which is often required in safety applications.
