WAM Butterfly Valves – VFS

VFS Butterfly Valves consist of two high-pressure die-cast semi-bodies manufactured from aluminium alloy, a swivel disc in SINT polymer composite or cast iron, and a prestressed elastomer seal.

WAM VFS Butterfly Valve


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 is required. VFS Butterfly Valves can be fitted beneath hoppers, bins, silos, screw or other type conveyors, or for material interception in pneumatic conveying ducts. Due to their special design and to the engineering materials used, they represent a particularly economic yet most efficient solution.

For the food industry a version with stainless steel disc and integral FDA-approved seal is available. While V1FS comes with a top flange and a bottom section suitable for the attachment of a flexible sleeve, V2FS has an identical top and bottom flange. VFS valves can be fitted with a manual lever or a pneumatic or gear motor actuator.
