Crane FKX9000 Triple Offset Butterfly Valves


The Crane®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.
