XMCERA | Ceramic Disc Valve for Tap
Why Ceramic Disc Valve
① The use of high-tech new ceramic structural materials, improve the wear resistance of the valve products, corrosion resistance and tightness, greatly prolonging the service life of the valve.
② The use of ceramic disc valve can greatly reduce the number of valve maintenance and replacement, improve the safety and stability of the operation system of supporting equipment, reduce the labor intensity of workers, save the cost of equipment repair.
③ The use of ceramic disc valves can improve the sealing of industrial piping system, and can maximize the elimination of leakage, which will play a positive role in promoting environmental protection.
④ Manufacturing ceramics of raw materials wide, low cost, with aluminum, carbon, silicon and other ordinary elements can be made of superior performance of ceramic materials, can save a lot of metal materials and rare mineral resources.

Applications
Ceramic disc valve is widely used in many industries such as lock bucket, bin, pneumatic conveying and all kinds of pipes in chemical industry, petroleum industry, mining industry, electric power industry and environmental protection industry. Combined with the characteristics of ceramic materials, it can work normally continuously for a long time under bad conditions with wear and erosion materials.
