Butterfly valves A480, whether manually or automatically operated, can be used in most liquid product applications in the food-processing, pharmaceutical and chemical industries. 。The design of the butterfly valve between flanges A490 facilitates its installation and maintenance, allowing the extraction of the valve by means of 4 screws while the flanges welded to the installation remain fixed.
Sanitary butterfly valves 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.
