The BFD series has a cast iron body, 316 S.S disc, EPDM seat and an electric actuator making it suited to a wide range of industrial applications. These wafer butterfly valves will fit all standard flanges and are operated by a high quality IP67 electric actuator (available in all voltages). The unique bonded catridge design of the butterfly valve gives it a longer life span, allows vacuum to be run through it and enables the seat to be replaceable if ever the need should arise. Common applications include water trucks, irrigation, cement hoppers, irrigation and other industrial applications. If sizes above 600mm are required please contact us.
