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.

Compact and robust design.
Multi-position handles as a standard feature for valves up to DN-100/4".
Two-position handle as a standard feature for valves starting from DN-100/4".
Several models of easily interchangeable manual handles and pneumatic or electric actuators.
Low-pressure losses.
Body halves are interchangeable with any connection type.
Connections: DIN 11850.
