Forged steel ceramic ball valve

Short Description:

All parts of ceramic ball valve in contact with the medium are made of structural ceramic materials. Its chemical stability and hardness are very high (Rockwell hardness hrc90), second only to diamond. Therefore, the valve has high wear resistance, corrosion resistance, erosion resistance, good heat insulation and small thermal expansion, which is widely used in power plant desulfurization system, washing and beneficiation system, fluid meteor control system, chemical industry and other strong corrosion occasions
