Business
We are one of the few valve manufacturers that can design, cast, process, and assemble cast iron valves in an integrated manner. We design and manufacture large valves, special valve, and we have tracking record of valves in Japan and overseas. Besides, we also have developed our own technologies for water and sewage and provide engineering that meets with user demands, which are also used in water treatment by the private sector in food factories. We are working on biomass, plant delivery centering in dairy industry in Hokkaido as a new initiative.
Domestic
Our featured valves (which can adjust the flow rate and reduce cavitation that affects the maintenance of the inner pipe surface) have been used in more than 60 countries in ODA projects so far. We also conduct a NEDO demonstration survey (2014, 2020) on quality industrial water manufacturing technology in Thailand; we proceed with commercialization with local industrial park development firms.
