Ceramic valves are used in industries: petroleum, chemical, power plants, steel, paper, bio-engineering, and other industries. Apply grain sea transport and high hardness of granules, containing soft particles and corrosive media, boilers, steam and lime slurry, powder, flue gas desulfurization, ash, slag, water treatment. Use replacement materials, can be used for different temperature and medium. In the face of high wear and corrosion, high temperature, high pressure, such as bad working conditions, ceramic valve shows its superior performance. With the continuous development and progress of science and technology, ceramic materials from the formulation, forming, machining and Assembly processes, and other technology is more mature and complete, ceramic valve for its outstanding performance to get the valve industry recognition.
