Zirconia ceramic ball 
 It has a metal ball than most of the advantages, but also has superior corrosion resistance, high temperature, wear and erosion resistance and other notable features. Widely used in petrochemical, metallurgy, paper making, power plants, oil refining and other industries of various types of acid-base salt, gas, liquid, high temperature steam and mud delivery system. Is highly corrosive situations titanium valves, Monel valves ideal alternative. Zirconia ceramic ball with a low cost, high operating economy and long life (titanium valve 2 to 4 times) advantages. The drive with manual, pneumatic, pneumatic-spring reset, power and so on. According to user requirements and design various types of special ceramic valves. 
 ◆ anti-erosion, abrasion 
 Valve ball, valve seat and lining are made of zirconia structural ceramic materials, Rockwell hardness of up to HRA87 above, which can withstand high-speed fluid medium and hard particle erosion. Has excellent wear resistance. 
 ◆ corrosion ability 
 The Chinese Academy of Sciences, Institute of Corrosion and Protection, Inspection, and hydrofluoric acid solution in addition to glass, zirconia ceramic material with excellent corrosion resistance. 
 ◆ long life 
 Hefei General through the Department of the static mechanical life test, switch a million times still leaking. 
 ◆ wide range of applications 
 For a variety of acids, alkalis, salts, liquid, gaseous media environment, especially for hard-sealed valves with granular, fibrous media environment.
