This series is concentric segmented 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.
Series 230C is the 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.
Valves Series 210C / 220C / 230C are used in the following industries:
Heavy duty, long durability for wide range of applications with media temperature -196 to 565° C and presssure up to 310 bar
details
Cage guided valves with balanced trim -196 to 538° C media and pressure up to 170 bar
