  Sun Yeh Ceramic Lined Valve in Poly-Silicon   Industry Polycrystalline silicon is an important semiconductor material widely used in photovoltaic cells, integrated circuit chips, and other fields. In the production of polycrystalline silicon, various valves are needed for the transportation and control of raw materials. However, due to the specificity of polycrystalline silicon materials, ordinary metal valves often cannot meet the requirements of its production process. The production process of polycrystalline silicon involves stages such as pneumatic feeding, reactor feeding, granular silicon process, hydrogen chloride process, silicon tetrachloride converter drum, filter slag outlet, final high-pressure storage, and exhaust gas treatment, presenting the following challenges for valves:   Corrosion Resistance: Chemicals used in the production of polycrystalline silicon, such as hydrogen chloride (HCl), are extremely corrosive. Sun Yeh ceramic-lined valves can resist ...

  Sun Yeh   95MT ceramic lined butterfly valve   Series, its seat and spool are precision ceramics, double eccentric, sealed torque, and has functions of switching and regulating.
