  • Valvematerial

    Gray iron, ductile iron and malleable iron are the threekinds of iron used for valve construction. Unlike grayiron, which has thin, flake-like molecular formations,the metallic structures of both ductile and malleableiron contain nodular graphite. (Refer to the microscopicviews shown here.) This structure provides ductile andmalleable iron with mechanical properties which exceedthose of gray iron. lt almost equals the properties ofcast steel, which is an expensive material for industrialvalves. Furthermore, their superior castability andmachinability help to increase their suitability as a vaIvematerial.

    Ductile iron outperforms malleable iron due to its bettermechanical characteristics to build valve body, which is akind of pressure containing device. For example, it has a20% higher tensile strength and 70 to 80% better elon-gation.This difference comes from different formationprocess of nodulated graphite molecules.

    KITZ ductile iron valves are made of JIS FCD-S or ASTMA395 ductile iron. The history of the introduction ofductile iron valves on the market is rather short, howev-er, the de-mand is steadily increasing as a result of theireconomic advantage as well as the fact that their widerange of service applications is comparable with caststeel valves.

    This catalog serves to provide design specifications,materials of construction and external dimensions of thefollowing ductile iron valves and strainers manufacturedby KITZ Corporation :

    JIS 10K,16K & 20K Gate, Globe & Check ValvesJIS 10K & 20K Ball ValvesJIS 10K, 16K & 20K StrainersASME 150 & 300 Gate, Globe & Check Valves

    For higher mechanical shock resistance under highor Iow temperature, and better tensile strengthand elongation characteristics than those of ordi-nary gray iron valves, ductiIe iron valves are highIyre-commended for the following services, some-times, in place of cast steel valves :
