Butterfly Valve Sandwich 4900


Sandwich butterfly valves, whether manually or automatically operated, can be used in most liquid product applications in the food-processing, pharmaceutical and chemical industries. The design allows to easily instal or remove the valve without separating the pipes.

Operating principle

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