    Metal to metal ball and seat set includes one ball and two seats for metal seated ball valve. They are already lapped together and tested with alcohol or kerosene to guarantee as zero leakage or bubble tight seal. 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 metal seated sphere
    The hard sealing ball is supported by the upper and lower bearings to reduce friction and eliminate the excessive torque caused by the huge sealing load formed by the imported pressure pushing the ball and the sealing seat. It is mainly used to cut off, distribute and change the direction of the medium flow in the pipeline, and can be discharged Retention in the middle cavity can reduce the pollution of the medium to the valve, reduce the operating torque of the ball valve and increase the reliability of the seal. The hard sealing ball has the advantages of high hardness, strong wear resistance, smooth and smooth passage, and not easy to deposit medium.

    The applicable media and application fields of the hard sealing ball
    The hard-sealed sphere is suitable for media containing hydrogen sulfide, hydrogen, carbon monoxide, and chloride ions, which improves equipment utilization and saves money. It is widely used in petroleum, chemical, and urban central heating industries. It is suitable for various high temperature and high pressure water, steam, petroleum, coal, steel and other industries.
