Butterfly Valve 2-30 Inch with Bonded Seat (Series BFI)


The VSI Waterworks’ BFI Butterfly Valve was designed to be an economical flow control solution for line sizes of 2” through 30”. The body is fully lined with resilient material to match the line media’s properties, allowing no media-to-body contact. The concentric design features a one piece shaft, which is available in a variety of materials and pinned to a standard ductile iron or stainless steel disc. The streamlined disc guarantees low cavitation and high valve coefficients. Valves in this line are designed and constructed to meet and exceed AWWA C504.
