For the mainstream production technology of high-end mixing proof valve in the internationalindustry, all of the bodies are forged by raw steel based on the finish turning moldingtechniques of CNC. Shanghai Yuanan are devoted to the design and development of sanitaryvalves, we persist on the leading techniques in the industry, improve the previous technologyto the forging production process based on the exquisite research of technical engineersand walk together with the internationally mainstream high-end valves. The forging andmanufacturing process of raw steel obtains strong rigidity and it can bear strong acid-baseunder the temperature function, the whole set import of sealing ring in key accessories makevalves can stably operate at the process pipe for a long time.
