Flour Milling VFS Butterfly Valves Description VFS Butterfly Valves consist of two high-pressure die-cast semi-bodies manufactured from aluminium alloy, a swivel disc in stainless steel or cast iron, and a pre-stressed elastomer seal or an integral seal. While V1FS has a top flange and a beaded bottom section suitable for the attachment of a flexible sleeve, the V2FS comes with an identical top and bottom flange. Applications VFS Butterfly Valves are used in all types of flour mills where interception of gravity-fed or pneumatically conveyed dry materials is required. Typical applications are storage, transport and processing lines. They are fitted beneath hoppers, bins, silos, screw or other type conveyors, or to intercept pneumatic conveying ducts. Due to their special design and to the engineering materials used, they represent a particularly cost-effective yet most efficient solution. No contamination due to metal steel disc and NBR white seal; Dust-tight thanks to components geometry; Suitable for different materials in the same configuration; Safety for OEM and end user thanks to ATEX zone 22 certification; Quick integration into the process; Modular design and easy maintenance thanks to small numbers of components; High flexibility thanks to interchangeable components. For closing bins, hoppers and silos containing powders or granular materials, VFS Butterfly Valves are among the most widely used equipment worldwide. What used to be custom-built items for specific applications, have been turned by WAM® into a mass-produced industrial product with features that allow extremely versatile use.
