Powder Handling System


  VALVES -- [ Butterfly Valves ]

Description :

Butterfly Valves consist of two high-pressure die-cast semi-bodies manufactured from aluminium alloy, either a steel core disc coated with unique SINT®-polymer composite (optionally FDA-approved) or a cast iron disc, and a pre-tensioned elastomer seal.

The food industry offers a version with stainless steel disc and integral seal.

While V1FS has a top flange and a bottom section suitable for attachment of a flexible sleeve, V2FS comes with identical top and bottom flange.


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 into a mass-produced industrial product with features that allow extremely versatile use.
VFS Butterfly Valves are used in all types of bulk solids 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 to the engineering materials used, for many years they have represented a particularly economic yet most efficient solution.
