Macon’s BFV Butterfly Valves are Lug Type. The heavy duty one piece
body is designed to be installed between all types of ANSI 125 / 150
flanges. Resilient seat provides bubble tight shut off. Blowout proof stem
with pinned disc. Universal mounting flange conforms to ISO-5211. The
2.5” through 6.0” sizes are supplied with an adjustable flow positioning
plate. This unique design provides quick and easy setting of the valve flow
position, requires less hardware, will not slip and allows the valve to be
easily moved to the closed or full open position without disturbing the
flow positioning set point. The 8.0” through 12.0” size Butterfly Valves
feature a gear operator.
Optional features and accessories available
