Description
Zoloto’s butterfly Valve (Wafer Type), PN 2.5 with S.S 304 Disc Body S.G Iron, Lever Operated, Nitr is supplied in 40 mm to 150 mm. 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. Lever operated, so the position is readable from across a plant room. Ductile iron carries considerably more strength and impact resistance than grey cast iron for the same section — the reason it is specified for buried and higher-pressure mains. The wafer body clamps between two pipe flanges, keeping face-to-face length and weight to a minimum. Full dimensions, catalogue references and current pricing for every size are listed in the table above.
