The BFD (supercedes the BFK) series has a fushion bonded expoxy coated cast iron body, 316 S.S disc and an EPDM seat (standard but also available in FKM) making them suited to a wide range of general water applications. These wafer butterfly valves will fit all standard flanges and are operated by either a lever or gear box. The unique bonded catridge design gives them a longer life span, allows vacuum to be run through them and makes them 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, cement hoppers and other industrial applications. If sizes above 600mm or extension shafts are required please contact us. For details on the gear boxes please click here.
