Characteristics of the product structure◆ erosion resistance, wear resistance - valve ball, valve seats and linings are made of zirconia structural ceramic materials Rockwell hardness of up to HRA87 above, which can withstand the erosion of the high-speed fluid and hard particles of the medium. Has excellent abrasion resistance.◆ corrosion ability - the metal of the Chinese Academy of Sciences Institute of Corrosion and Protection of inspection, in addition to glass solution and hydrofluoric acid, zirconia ceramics have excellent corrosion resistance.◆ long life - the life test, the static pressure through the Ministry of Machinery Hefei General switch a million times still leaked. Engineering ceramics, also known as structural ceramics, and the essential difference between the ordinary ceramics. Valves for use on ceramic materials TZP, its raw material zirconium gem materials, spray granulation, static suppression of the high-temperature sintering, precision machining, the 'fragility' of the ceramic has been greatly improved, its toughness and strength has been greatly improved, the industry referred to as 'ceramic steel'. TZP ceramics not only has high toughness, high strength, high hardness, high wear resistance and high corrosion resistance can, but also self-lubricating, low thermal conductivity, excellent surface finish (Ra up to 0.01um) , is an excellent replacement material for valve metal material. Zirconia Ceramic Ball Valve Scope of applicationUrban construction, chemical, metallurgy, petroleum, pharmaceutical, food, beverage, environmental protection
