Our Business

Since SHIDA KOMUSHO Co., Ltd was founded in August, 1919, it has been designing and manufacturing excellent safety valves, pressure reducing valves and various automatic regulating valves, creating new ideas and technologies. In 1956 the company became a limited company and installed the state-of-the-art machine tools. We have continuously provided various valves to nationwide companies related to LNG gas, LPG gas, nuclear power plant, steel manufacturing, fertilizer producing, paper making, synthetic fiber producing, ship building and blower making. We have exported products to Russia, China, Taiwan, South Korea and Singapore.

In October, 1971 we built a test and inspection factory of 330 m2 and have strived to educate our people and to advance the quality control system. In May, 1976 we were certified as a manufacturer of valves for high pressure gas, and accredited as an inspection executor of valves for high pressure gas, by Minister of Trade and Industry. In 1986
the certified range of temperatures in specifications was extended to cryogenic temperatures. We have advanced to the field of cryogenic temperatures, providing a higher level of valves, including pressure reducing valves, pressure regulating valves and check valves.
