VMV bellows-globe family material list. JS1049 is the listed ductile-iron family alternative. Material options require their own pressure-temperature and medium review; the dimensional table does not establish identical mass or suitability for every combination.
Bellows-sealed valves, strainers, check valves and steam traps for steam supply and condensate return lines.
