The BFD (supercedes the BFK) series has a cast iron body, 316 S.S disc, EPDM seat and a spring return 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 spring return (rack and pionion design) anodised aluminium pneumatic actuator. This enables a fail safe position if air should be lost. 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, water treatment and other industrial applications. If using on a cement hopper please contact us. We recommend going up a size in actuator to compensate for the weight on the disc. If sizes above 600mm are required please contact us.
For Sprung Open the ‘5’ in the product code changes to a ‘6’.
For sizes over 600mm or different seat material please contact us.
