Yongjia Tong Ball Valve Co., LTD., as KITZ's strategic supplier of precision balls in the global supply chain, has long provided core ball accessories for its high-end industrial ball valve product line. The cooperation between the two sides is based on precision manufacturing and deep adaptation that exceed standards.
To ensure that the products are absolutely compatible with KITZ's globally unified and extremely strict technical specifications, our production management system is built around the concept of "Zero Tolerance Delivery".This means not only micro-level control of sphere roundness, surface roughness (Ra≤0.1μm) and dimensional tolerances, but also that our quality control processes are deeply embedded in KITZ's global supplier management systems (such as GPMS).From the raw material batch traceability, key processes of SPC (statistical process control) data real-time upload, to the finished product delivery before completion and KITZ standard parts library of virtual matching verification, the whole chain data to achieve seamless docking and double verification.
Thanks to this deeply integrated "systematic adaptation" capability, every batch of spheres we deliver can be ensured to be "assembled immediately upon arrival" on KITZ's globally distributed automated assembly lines, significantly enhancing its supply chain efficiency and production flexibility. Based on its outstanding performance in quality stability, on-time delivery rate (OTD ≥ 99.5%), and technical collaborative response, Yongjia Tongqiu has become a highly trusted and irreplaceable precision manufacturing partner of KITZ.
