The part where ceramic ball valves come into contact with the medium is made of structural ceramic materials, which have extremely high chemical stability and hardness (hardness HRC90), second only to diamond in hardness.
Therefore, this valve has extremely high wear resistance, corrosion resistance, and erosion resistance, as well as good insulation and low thermal expansion.
They are mainly used in industrial fields such as power, petroleum, chemical, metallurgy, mining, sewage treatment, etc., especially in harsh working conditions such as high wear, strong corrosion, high temperature and high pressure.
The ball is processed by advanced grinding equipment with high technology.
The ball has high roundness accuracy, good surface quality.And after grinding with the valve seat, it utilizes the self-lubricating property of structural ceramics to have good sealing performance. This completely changes the disadvantages of metal seat ball valves such as easy leakage, high torque, and poor corrosion resistance of sealing surfaces.
The valve seat and ball have good wear resistance and long service life, which is 2 to 4 times that of titanium alloy valves and Monel valves.
