Description
Audco cast Iron Butterfly Valve (CI Disc, Nitrile Liner, Gear operated, PN 10), available 50 mm to 300 mm at PN 10. A quarter turn moves the disc through the full stroke, so large-bore lines can be operated quickly without a gearbox in the smaller sizes. 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. The table above gives the catalogue reference and price for each size in the range.
