Function

To close silos, hoppers or bins containing powders or granules, VFS Butterfly Valves range among the most widely used equipment worldwide.
What used to be custom-built items for specific applications, WAM has turned into a mass-produced, industrial product with features that allow extremely versatile use.
VFS Butterfly Valves are used in all types of powder and granular material processing plants where interception of gravity-fed or pneumatically conveyed dry materials is required. They are fitted beneath hoppers, bins, silos, screw or other type conveyors, or to intercept pneumatic conveying ducts. Due to their special design and engineering materials used, they represent a particularly cost-effective yet most efficient solution.
