1 Product model:
a) Koso 210E: Eccentric Segmental Ball Valves(Flowmax E/Wafter)
b) Koso 220E: Eccentric Segmental Ball Valves(Flowmax E/Flanged)
koso valve 210E & 220E is eccentric segmental ball valve for modulating application.
Comparing to globe valve, body is compact, ligh weight, and yet it has large Cv value, large rangeability,and can be convertible to reduced bore type (60, 40% reduce ) by changing seal ring only.
