Utsue Valve was manufacturing valves for ships from our founding until shortly after the war. Before and during the war, our valves were installed in the battleship Musashi (sister ship of the Yamato), which was manufactured by the Nagasaki Shipyard of Mitsubishi Heavy Industries, Ltd. After the war, we changed our focus from valves for ships to industrial valves for land use. Currently, we are working on the production of high temperature and high-pressure valves used in thermal power and nuclear power plants.
