Polycrystalline silicon, a high-purity silicon material renowned for its stability, conductivity, and low resistivity, finds extensive applications in solar cells, semiconductors, and chemical catalysts. Neway has made significant breakthroughs in high- and ultra-pure polysilicon production, utilizing processes such as the Siemens method and fluidized bed processes with silane, achieving import substitution. We also supply specialized valves, including hard-sealed and high-temperature ball valves, for various polysilicon production equipment like cold hydrogenation units, silica powder separators, distillation apparatus, reduction furnaces, and adsorption towers. Furthermore, we have developed rotating disc valves tailored for polysilicon industry equipment and other powder-handling systems. A comprehensive polysilicon valve design quality control framework ensures rigorous oversight of production and design processes, guaranteeing product reliability.
