Materials & Components
Incoloy valves may use Incoloy 800, 800H, 800HT or 825 for applicable body, bonnet, disc, ball and other wetted components. Stems, shafts and trim may use Incoloy, nickel alloys or compatible stainless steels. Graphite, PTFE, RPTFE or metal seats can be selected according to temperature and service, with flexible graphite or PTFE-based packing and graphite, PTFE or spiral-wound gaskets. Material selection depends on the fluid, temperature, pressure, thermal cycling and oxidation conditions.
