4800 Butterfly Valve
Operating principle
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.
Design and features
Compact and robust design.
Multi-position handle as standard feature for valves up to DN-100/4″.
Two-position handle as standard feature for valves starting from DN-100/4″.
