Description
Sant’s butterfly Valve Wafer Type (Gear Operated) is supplied in 200 mm to 400 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. 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. Flanged ends make the valve straightforward to remove for servicing without cutting pipe, and are the norm once bore and weight rule out threaded joints. Full dimensions and current pricing for every size are listed in the table above.
