Zirconia ceramic ball valves, butterfly valves, and gate valves not only have the advantages of metal valves, but also have the characteristics of wear resistance, acid and alkali resistance, corrosion resistance, high temperature resistance, high toughness, and anti-static. Therefore, they can be used in harsh environments without polluting materials and the environment; Applied in various acid, alkali, salt gas, liquid, high-temperature steam, and slurry transportation systems in industries such as petrochemicals, metallurgy, papermaking, power plants, and oil refining. This product's precision and wear resistance are not affected by thermal expansion, and it has better operability and long service life in harsh environments or fluids. Zirconia ceramic ball valves have the advantages of low cost, high operational economy, and long service life.
