Cast Iron Wafer Butterfly Valve
KBN Engineers Cast Iron Butterfly Valves are wafer pattern valves that fit between two pipe flanges, saving space and weight compared with gate valves of the same size. A quarter turn of the lever fully opens or closes the line.
Bodies are available in cast iron, SS304 and SS316, with C.I. or CF8M discs. Each valve is hydro tested at 225 Psi (16 Kg/cm²) on the body and 165 Psi (11 Kg/cm²) on the seat.

Quarter-Turn Operation
Lever-operated disc opens or closes the line with a 90° turn, for fast isolation.
Compact Wafer Body
Short face-to-face length and low weight make it easy to fit between existing flanges.
