Description
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 full fill a quick closing time, which is often required in safety applications.
