DATA SHEET

The BFL series has a lugged (in a choice of table E or table D/AS4087 PN16) cast 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 lever or gear box. The unique bonded catridge design gives them a longer life span, allow 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 sizes above 600mm double flanged is used. Please contact us for details.
