Details -★, all parts in contact with the media are structural ceramic materials, their chemical stability and high hardness (Rockwell hardness of HRC90), second only to diamond. Therefore, the valve has a very high resistance to wear, corrosion resistance, erosion resistance and good heat insulation, small thermal expansion.★, ball using advanced grinding equipment and process manufacturing, high-precision ball roundness, surface quality, the seat of the study, self-lubrication of Zr02 ceramics, can be achieved very good sealing performance.★, completely changed the metal seal valve easy to leak, torque, and the shortcomings of the sealing surface of impatience corrosion.★ good wear resistance of ceramic, so that the valve durability, high reliability, long life, titanium valves and Monel valve 2-4 times.★, granular media for high hardness, or soft particles but there are corrosive media, this valve has the absolute advantage of unparalleled, is currently the only suitable medium for such valves.In addition to the vast majority of the advantages of a metal ball valve, zirconia ceramic ball valve features and performance zirconia ceramic ball, but also has superior corrosion resistance, high temperature, wear-resistant and resistant to erosion and other notable features. Widely used in various industries of petrochemical, metallurgy, paper making, power plants, oil refineries and other acid-base salt, gas, liquid, high temperature steam and mud conveyor system. Strong corrosion occasions, titanium valves, Monel valves ideal alternative. Zirconia ceramic ball has a low cost, and running the economy of high and long life (titanium valve 2 to 4 times) advantages. Drive a manual, pneumatic, pneumatic spring return, electric. And according to user requirements and design various types of special ceramic valves. Erosion resistance, wear-resistant: valve ball, valve seats and linings are made of zirconia structural ceramic materials, Rockwell hardness of up to the HRA87, and thus able to withstand the erosion of the high-speed fluid and hard particles of the medium. Has excellent abrasion resistance. Corrosion: Corrosion and Protection of inspection by the Chinese Academy of metal, in addition to glass solution and hydrofluoric acid, zirconia ceramics have excellent corrosion resistance. Long life: the Ministry of Machinery Hefei General hydrostatic life test, switch a million times still leaked.
