Lugged & wafer type butterfly valves
Butterfly valves comprise of a disc that rotates in the passageway to stop and start flow through a 90 degrees turn. As well as having good shut off capabilities, a butterfly valve can be secured into intermediate positions using the lockable handle for flow regulating purposes.
Butterfly valves benefit from a compact design, making them ideal for applications where space is limited and costly materials are required. Thanks to their low pressure drop and high pressure recovery, lever operated butterfly valves are also a good solution for large pipe installations.
