Global Valves

In severe services of high temperature and high differential pres-sure, KOSO's multi-stage trim (Pat.) promises accurate control and long life, free from cavitation erosion and noise problems, whether the fluid is compressive or non-compressive.

This Series is multi-ad-vantageous in that its improved performance and durabitity allows maintenance cost reduction and system simplification. Since such ancillaries as diffusers and silencers are not necessary, equipment cost can be reduced too. From 500M, 500D and 500J, depending on the fluid condition, most suitable model can be selected comparing functions and prices.

Gate Valves

Parallel slide has KOSO's own design/construction to realize very good and firm metal-to-metal touch sealing performance. Its execellent shut-off performance, brought about by the metal-to-metal sealing, makes it suitable to a variety of severe services, including emergency shut-off/opening at extremely low to high temperature.

Ball Valves

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.

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.

Butterfly Valves

This PARA-SEAL valve is high performance butterfly valve of high durability, high seating performance. It has several different seal ring constructions suitable to various service applications.
