3-Piece Flanged Cast Steel Ball Valves
Reducing Flanged Ductile Iron Ball Valve
A reducing flanged ductile iron ball valve features a 3-piece flanged ductile iron body with a sphere bore one size smaller than the pipe inside diameter. Thanks to the smaller sphere and body, it is lighter, more compact and more economical than full bore valves.
It is preferred in heating, cooling and general water lines where minor pressure loss in flow is not a concern. Available in sizes DN20 to DN300 and pressure classes PN16 and PN40; it provides long-lasting sealing integrity with stainless steel sphere and PTFE seats.
