New ceramic ball valve new ceramic material sealing parts and vulnerable parts of the ball valve, improves the wear resistance, corrosion resistance and sealing of the valve, greatly extend the service life of the ball valve. Ceramic wide range of raw materials, low cost, aluminum, carbon, silicon and other common elements can produce superior performance ceramic materials, can save a lot of metals and rare minerals. Ceramic valves used in electric power, petroleum, chemical industry, metallurgy, mining, wastewater treatment, industrial areas, wear-resistant, good sealing, can minimize leakage, will play a positive role in promoting the environmental protection
