Bottom Padding

Since its founding in 1965, KOSO has developed a broad range of control valves, improving and enhancing many industries’ process automation performance. The company has now grown into a global valve manufacturer that provides even more diverse control solutions, with ten group companies within Japan and twenty three companies overseas now.

In our global valve business, our wholly-owned manufacturing operations in China and India are even stronger because our factory owned & operated foundries are included in our internal company supply chain. This enables us to provide customers with complete high quality, high pressure valves sourced under our direct control.

As part of our global expansion of new valves manufacturing, sales & service operations outside of Japan, we have added Parcol of Italy, with a 65 year history, making our global support network even more responsive to customer needs.

Meanwhile, in the control systems business we are expanding our product lineup, with innovative developments, such as the KGP Series of KOSO smart positioners, and REXA, our unique brand of electro-hydraulic actuators.

Supporting all of our global business efforts is the firm belief in originality held by each and every employee since our founding, with which to create better service and higher-quality products and provide unmatched solutions under the Made in KOSO credo.

KOSO will continue to meet challenges into the future to become even more useful to customers.

Yuichi Ikegaya, CEO
KOSO Group
