Lugged Ductile Iron Double Acting Butterfly Valve
SKU: BFLDA
The BFL series of lugged butterfly valves (table E & table D/AS4087 PN16 standard) have a cast iron body, 316 S.S disc and an EPDM seat making them suited to a wide range of general water and industrial applications. They are operated by either a high quality anodised aluminium double acting (rack and pinion design) pneumatic actuator. The unique bonded catridge design of the valve gives it a longer life span, allows vacuum to be run through it and makes it replaceable if ever the need should arise. Common applications include water trucks, irrigation, cement hoppers and other industrial applications. If sdifferent flange standards or different seat materials are required please contact us.
