Medium temperature wax casting ball valve is a high-end valve product that integrates medium temperature wax investment casting technology and ball valve structure design. It is mainly used in various industrial fluid systems (such as petrochemical, power, water supply and drainage) to achieve precise flow regulation and cutoff control of liquids, gases, steam and other media. Its advantage lies in the use of medium temperature wax casting to achieve high-precision molding of complex valve body structures, ensuring long-term stable operation of ball valves under harsh working conditions (high temperature, high pressure, strong corrosion), and meeting the modern industrial demand for valves with "high performance, long service life, and maintenance free".
