butterfly valves are primarily used in industrial applications and the chemical industry, as well as the fields of water supply and water/waste water treatment. The concentric and single-eccentric designs are available as standard. However, the double-eccentric and triple-eccentric shut-off valves are also available for projects on request. Use of matched control components such as position indicators, positioners and process controllers allows butterfly valves to also be used in control circuits.
