Description
Audco’s cast Iron Butterfly Valve (CI Disc, EPDM Liner, Gear operated, PN 10) is supplied in 50 mm to 300 mm at PN 10. 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. Gear operation keeps the effort manageable at the larger bores, where a lever would need more force than one person can apply. 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.
