Fitted beneath silos, hoppers, or bins, VFF Silo Closure Butterfly Valves are used in all types of building material processing plants where interception of gravity-fed dry materials is required.
VFF-type Silo Closure Butterfly Valves are manufactured from a one-piece fabricated carbon steel body lined with engineering polymer composite. Due to the four corner slots the integrated upper square flange can be adapted to different sizes of silo outlet flanges. The valve disc is manufactured from surface-treated carbon steel.
