Description
Audco’s cast Iron Butterfly Valve (SG Iron Disc, EPDM Liner, Lever, PN 16) is supplied in 50 mm to 300 mm at PN 16. Butterfly valves become the economical choice as bore increases: the disc rotates within the body rather than lifting clear of it, so the valve stays short and light where a gate valve would be neither. Lever operated, so the position is readable from across a plant room. The IS 210 cast iron body is the economical choice at larger bores. It suits steady water service but not lines that see mechanical shock. Full dimensions, catalogue references and current pricing for every size are listed in the table above.
