Butterfly valves
Butterfly valves
Butterfly valves regulate the flow of liquids or gases in pipelines. The closing element is a disc mounted on a rotating shaft, which turns during opening or closing to control the flow of the medium.
Center Line, FKX900L, and Xomox butterfly valves operate across a wide temperature and pressure range, even under vacuum. They are designed for frequent on/off operation and long service life.
