In the harsh environment of chemical industry, coal, oil and so on, metal valves can no longer meet the needs of harsh working conditions such as high abrasion and strong corrosion, which are mainly manifested in the situation that the metal valve is easily leaked, the torque is large, and the sealing surface is not resistant to corrosion. The traditional metal valve urgent need from the material, design and processing technology and other aspects of the radical reform. The application of ceramic materials to industrial valves is a bold and rewarding innovation.
