The BFL Series of Butterfly Valves is a fusion bonded epoxy coated Ductile Iron bodied valve with a 316SS Disc and EPDM seat (FKM and NBR available as option - Contact Sales). The lugged design is available to suit multiple flanges (AS2129 Table E, AS4087 PN16 / Table D, ANSI 150) and can be operated by the standard lever or actuator / gearbox. The seats are a unique bonded cartridge design that allows vacuum to be run through the valve, allows renewal of the seat and gives a longer lifespan to the seat. This valve is suitable for a wide range of general and watermark water applications such as water trucks, cement hoppers, irrigation and other industrial applications.
