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.
