    XINZHAN VALVE BALL CO., LTD. is specialized in producing of floating type valve balls according to customers’ drawings. The floating sphere is floating. Under the action of the medium pressure, the sphere can produce a certain displacement and press tightly on the sealing surface of the outlet end to ensure that the outlet end is sealed. The floating sphere has simple structure and good sealing performance, and is widely used in industry. Warm reminder that when the ambient temperature is higher than the boiling point, the inner cavity of the floating sphere will expand excessively due to being greater than the yield stress of the valve body material, and even fail. The two most important characteristics of the valve balls are the roundness and the surface finish. The roundness must be controlled especially in the critical sealing area. We are able to manufacture valve balls with extremely high roundness and high surface finish tolerances.

    Advantages of floating sphere
    The floating sphere has high work efficiency, safe operation, good working conditions, no “three wastes” and environmental pollution. It has the advantages of compact material, no slag, sand holes, pores, light weight and high strength. It is used in petroleum, natural gas, water treatment, medicine and chemical industry, heating and other fields. The floating sphere is compact and reliable, and easy to maintain. The ball valve has a simple structure and is generally movable. It is convenient to disassemble and replace.

    Xinzhan valve balls are used in various ball valves which are used in the fields of petroleum, natural gas, water treatment, medicine and chemical industry, heating, etc.
