Description
This SG Iron Butterfly Valve (SG Iron Disc, Nitrile Liner, Gear operated, PN 20) from Audco covers 50 mm to 600 mm at PN 20. Compact and quick to operate. Face-to-face length is short, which matters where a valve has to fit an existing pipe run. Gear operation keeps the effort manageable at the larger bores, where a lever would need more force than one person can apply. An SG iron body to IS 1865 tolerates ground movement and pressure surge in ways grey cast iron does not. Size-by-size catalogue numbers and pricing appear in the table above.
