The butterfly valve can be operated automatically through an actuator or manually with a handle.
The handle blocks the valve in the "open" or "closed" position, although there are also other models with intermediate positions.The actuator transforms the axial movement of the piston into a 90º rotary movement which it transmits to the disc.
