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.
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.
