BVFS Butterfly Valves consist of two high-pressure die-cast semi-bodies manufactured from aluminum alloy, a swivel disc in polymer composite， cast iron or stainless steel, and a rubber seal.
BVFS Butterfly Valves are used in all kinds of powder and granular material processing plants where interception of gravity-fed or pneumatically conveyed dry materials is required. They are fitted below 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 and most efficient solution.
