Inoxpa A480/A490 Sanitary Butterfly Valves

Sanitary 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 it's 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 (sanitary pneumatic butterfly valve, sanitary butterfly valve with pneumatic 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
