Powdery And Granular Materials 100mm VFS WAM Butterfly Valve

Powdery and Granular Materials WAM Butterfly Valve VFS

WAM Butterfly Valve VFS consist of two high-pressure aluminium alloy die-cast semi-bodies, a SINT polymer composite or cast iron swivel disc, and a pre-stressed elastomer seal.
For the food industry a version with stainless steel disc and an FDA/EN-approved, integral seal is available.
While V1FS has a top flange and beaded bottom section – suitable for the attachment of a flexible sleeve – V2FS comes with identical top and bottom flange.

To close silos, hoppers or bins containing powders or granules, VFS Butterfly Valves range among the most widely used equipment worldwide.

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.
