Butterfly Valves

Butterfly valves are valves that the flow of gas or liquid or gas completely or partially closes with a disk that rotates to its diameter. Butterfly valves are mainly used as a valve but can also serve as a control valve. The open and closure can be controlled manually or automatically: electric or pneumatic.
Depending on the application, butterfly valves can be used in different versions.
