The BFL series has a lugged (in a choice of Table E or Table D/AS4087 PN16) ductile iron body, 316 S.S disc and an EPDM seat making them suited to a wide range of general water applications. These are operated by either a lockable lever & notch plate or gear box. The unique bonded catridge design gives them a longer life span, allowing vacuum to be run through them and makes them replaceable if ever the need should arise. Common applications include water trucks, irrigation, cement hoppers and other industrial applications. If size is above 600mm, double flanged valves are used. Please contact us for details.
