The BFD (supercedes the BFK) series has a cast iron body, 316 S.S disc, EPDM seat and a double acting pneumatic 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 double acting (rack and pionion design) anodised aluminium pneumatic actuator. 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. Designed & manufactured in accordance with API609, inspected and tested in accordance with API598. Common applications include water trucks, irrigation, irrigation and other industrial applications. If sizes above 600mm or extension shafts are required please contact us.
