    Valve Balls

    What’s the stellite alloy?

     It is a range of cobalt-chromium alloys designed for wear resistance, heat resistance and corrosion resistance.

    What’s the material of your valve seats?

    It’s the CoCrW alloy, which is usually called stellite alloy.

    Materials of  Stellite190 valve balls – Cobalt Chrome Alloy:

    Excellent wear and corrosion resistance even at high temperature up to 800℃。

    Stellite21 Valve Balls Product Features:

    1.Wear resistance: due mainly to the unique inherent characteristics of the hard carbide phase dispersed in a CoCr alloy matrix,

    it has exceptional wear and galling resistance.

    2.Corrosion resistance: this exellent and lovely property allows this kind of material parts to be used in oil&gas, slurry,

    acid liquid and any other mediums.

    3.High temperature resistance: the strength keeps stable up to 800℃ and it can even momentarily used at 1200℃.

    Stellite21 Valve Balls Application and Advantage:

    1. Valve balls and valve seats  are widely used  in pipeline valve.

    2. Valve Ball and Seat performance directly affects the use effect and service life of the pipeline valve.

    3. Each ball-and-seat combination is vacuum tested to ensure a perfect seal is obtained in all positions of contact.
