  • 210C: Concentric Segmental Ball Valves (FLOWMAX C/Wafer)
    This series is concentric segmental ball valve for modulating application. V-notch cut at disc makes rangeability larger and creates shearing effect by disc and seal ring. Therefore, suitable to large rangeability service and/or control of fluids with fiber and/or slurry.
  • 230C: Concentric Segmental Ball Valves
    This series is same as 210C series except that the stem penetrates the body and is supported by double gland packing.
    The stem’s blow out force is set off in this construction making it suitable to heavier services such as high pressure, high temperature service because of heat expansion insulation design stem.
