With way over a million units operating worldwide, WAM VFS-type Butterfly Valves for powdery and granular materials represent one of the Group's most industrial products.
VFS Butterfly Valves 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.
