VFS Butterfly Valves are used in all types of bulk solids processing plants where interception of gravity fed or pneumatically conveyed dry powders or granules are required.


VFS Butterfly Valves can be fitted beneath hoppers, bins, silos or other type conveyors, or material interception in pneumatc conveying. Single or Double Flanged Models are available.


For closing bins, hoppers and silos containing powders or granular materials, VFS Butterfly Valves are among the most widely used equipment worldwide.
