Description
Covering 50 mm to 300 mm at PN 20, this is Audco’s SG Iron Butterfly Valve (CF8 (SS 304) Disc, EPDM Liner, Lever, PN 20). The disc stays in the flow path when open, which costs a little pressure drop but keeps the valve short, light and cheap to support. Lever operated, so the position is readable from across a plant room. An SG iron body to IS 1865 tolerates ground movement and pressure surge in ways grey cast iron does not. Widely fitted on chilled water risers, cooling tower lines and large-bore service headers. Every size in the range is listed above with its catalogue number and price.
