- A metal flow (forging flow line) that follows the product shape is obtained, resulting in increased strength. - By applying pressure from a maximum capacity 2500t press, the structure becomes dense, with no internal defects. - By forging into a shape close to the final form, machining is reduced and weight is saved. - Weight reduction by thinning the wall thickness while maintaining the same strength.

The valve ball is not often visible to us in our daily lives because it is embedded in the ball valve, diligently fulfilling its mission. For example, it is used for fueling gas supply in space development rockets and in the coupling parts of hoses for tank trucks and fire trucks. It plays an important supporting role precisely because it is hidden. 【Delivery Achievements in Japan and Abroad】 ○ Domestic Industry in Japan ・Kitz Corporation ・Hisaka Works, Ltd. ・Kitamura Valve Manufacturing Co., Ltd. ・Hitachi Valve Co., Ltd. ・Toyo Valve Co., Ltd. ・Kobe Steel, Ltd. ・Kubota Corporation ○ Academic Research Fields ・Hokkaido University, Faculty of Engineering, Department of Nuclear Engineering ・Nara National College of Technology ○ Space Development Related (as end-users) ・NASA Space Science Institute (USA) ・Tanegashima Space Development Center, etc. We are now sharing the trust and technology cultivated over many years in Japan with the world.

A valve ball refers to the spherical component used inside a ball valve. The control of the fluid passing through the valve is significantly related to the performance of the valve, and the valve ball plays a crucial role in this. Therefore, the pursuit of perfect sphericity, which can be considered the lifeline of the ball, is not an easy task, especially in maintaining the prestige of a top manufacturer. Recently, the technology for machining spherical surfaces has been developed by Kida Valve Ball Company, allowing for a variety of uniquely shaped workpieces and prototype balls associated with new product development. With Kida Valve Ball Company's unique production system and in-house developed equipment, we can flexibly respond to high-quality, short delivery time demands, from small-diameter balls to large-diameter balls, and from small lots to mass production. □ For other functions and details, please download the catalog.
