Establishment Under Wartime Regime
1936	Started manufacture of mainly high pressure valves by establishing Shimizu Seisakusho in Kujo, Nishi-ku (West District), Osaka as a private enterprise of Ichinosuke Shimizu, who later became the first president of Kyoei Valve Ind. Co., Ltd.
1943	In November 1943, Kyoei Valve Ind. Co., Ltd was established with a capital of 430,000 yen through a merger with Asano Gokin (alloy) Seisakusho and several other enterprises in accordance with the Government Ordinance for Readjustment of Enterprises established during the war. [Photo]

Reconstruction During Post-War Turmoil
1945	Built foundations steadily as manufacturer of valve cocks for use mainly in chemical fiber and chemical industries as well as electric, petroleum, shipbuilding and machinery industries after the end of World War II.
1951	Approved as qualified factory for usage of the JIS (Japanese Industrial Standards) logo on bronze valves. (Currently no longer in production) [Photo]
1953	Osaka sales office moved to Nishitani Building in Minami Horie, West Osaka. [Photo]

Rapid Growth in Technological Innovation
1958	Supplied valves to factories in the chemical fibre industry following its development. Started developing bronze bellows sealed valves for transformers for power companies. [Photo]
1962	Liquefied nitrogen and oxygen were put to practical use as the result of advancement in gas liquefaction technology in America. Kyoei Valve started developing bronze cryogenic valves (SW and flanged Extended Bonnet Globe Valves) for cold evaporators (CE) and tank trucks. These became the very foundation of the current cryogenic valves. [Photo]
1963	Started development and manufacture of the more durable stainless steel valves in addition to bronze valves. This brought further improvement in the chemical fibre and high pressure gas industries. [Photo 1] [Photo 2]
1964	Shinichi Nishida, previously Senior Managing Director, assumed the position of Company President following the death of President Shimizu.

Development of Proprietary Know-Hows and Exploration of New Fields
1966	Received the Science & Technology Agency's Director General's Award for the invention of a high speed counter-boring machine. (Patent No. 485069 granted in November 1956) [Photo]
1971	Received permit as a high pressure gas equipment manufacturing facility from the Governor of Osaka.
1972	Certified as 'Factory for Testing and Manufacturing of High Pressure Gas Equipment' by the Minister of International Trade and Industry (19 Valves). This resulted in a rise in inquiries from major industrial gas manufacturers.
1974	Delivered valves to Tanegashima Space Centre for the ground fuel equipment piping system in connection with the N-1 rocket's launch preparation. This was the Kyoei Valve's first involvement in the space development sector. In line with this, a simple clean booth and cryogenic test apparatus were developed. [Photo]
1975	As the result of our supplying valves to the National Space Development Agency of Japan (NASDA) (presently JAXA: Japan Aerospace Exploration Agency), our cryogenic valves were recognized and adopted by major industrial gas manufacturers for use at their local and overseas plants. More inquiries and orders were received Korea, Taiwan and India. [Photo]

The Flight in Times of Economic Downturn
1976	Supplied a large quantity of vacuum jacketed valves for the H-I and H-II rockets' liquid hydrogen equipment. [Photo]
1976	In accordance with the newly revised High Pressure Gas Control Act, liquefied oxygen storage tanks with the capacity of 5000l and more are now required to be equipped with emergency shut-off valves. In response to this new requirement, Kyoei Valve successfully developed and commercialized its first Emergency Shut-Off Globe Valve. [Photo]
1977	Additionally certified as 'Factory for Testing and Manufacturing of High Pressure Gas Equipment' by the Minister of International Trade and Industry (16 Valves).
1978	Received visitors from the Chinese Society of Astronautics as the result of our supplying valves for the first domestically produced liquefied hydrogen tank truck. [Photo]
1980	Developed the Pressure Regulating and Pressure Releasing (Economizer) valves for cold evaporators (CE). The commercialization of these pressure regulators contributed to a bigger market coverage. In addition, with the successful commercialization of the Pressure Reducing Valve in the same year, our products are now applicable not just to cryogenic storage tanks but also plant piping systems.

1981	Business range was further expanded by acquiring certification for higher pressure valves. This made it possible for our valves to be used for high pressure semiconductor plant pipelines and the H-II rocket's ground testing equipment.
1982	Showcased our valves at the Cryogenic Equipment Expo at the Kobe International Exhibition Hall. [Photo]
1982	Successfully developed the vacuum jacketed Butterfly Valve for liquefied hydrogen. By subjecting the valve to severe endurance tests, we were able to achieve zero leak at operating temperature. The valves were adopted for various ground equipment of the H-II rocket. [Photo 1] [Photo 2]
1983	Reio Hamaguchi assumed the company presidency as former president Nishida was assigned to the post of Board Chairman.
1985	Reconstructed and expanded factories to double equipment and production lines.

System Planning for the 21st Century
1986	Commercialized the precision polished valves for high purity gas supply pipelines at semiconductor plants. With an inner surface roughness of Rmax 0.7µ, these precision polished valves became the foundation for our advancement toward the semiconductor industry. [Photo]
1989	Supplied valves to Osaka Gas for their LNG satellite base in Hikone. This started our full involvement in the LNG market. [Photo 1] [Photo 2]
1990	Received an award from the High Pressure Gas Safety Association of Osaka for excellent safety record and accident prevention approaches.
1992	Organized a company trip to Hawaii in conjunction with our 50th anniversary. [Photo]
1992	Received and award from The National Aerospace Development Agency (presently Japan Aerospace Exploration Agency) for our contribution in the development and successful launch of the H-1 rocket. [Photo]

2000	Delivered valves to the first LNG satellite base in China located in Zibo City, Shandong. Since then, our valves have been adopted by LNG bases built through out China. [Photo]
2001	Became an exhibitor at the 2001 China International Exhibition on Gases Technology, Equipment, and Application held in Beijing. Our participation in the event strengthened our reputation in the county's cryogenic industry. [Photo 1] [Photo 2]
2003	Obtained the ISO9001-2000/JIS Z 9001-2000 certification.
2004	Seigo Higuchi assumed the company presidency as former president Hamaguchi was assigned to the post of Board Chairman.
