KITZ 70 years history

Since its establishment in 1951 as Kitazawa Seisakusho, KITZ has been a comprehensive manufacturer of valves and other fluid control equipment. Based on the philosophy of the company’s founder, Toshio Kitazawa (1917-1997), KITZ has developed a system that provides customers with meticulous sales service and after-sales support based on integrated production from raw materials, through casting, machining, assembly, inspection and shipping, all done in-house. This commitment to “better quality” has continued to the present day and is the origin of our KITZ Group.
