ceramic ball valves ,the parts of contacts with the media all adopt the structure ceramics of a very strong corrosion resistance, which have the unmatched corrosion resistance that metal valves cant be, it is a ideal substitute for titanium valve and Monel valve under strong corrosion, At the same time it has extremely strong wear-resistant and erosion-resistant capability, the life is 2 to 4 times than titanium valve, which highlight its cost advantage. Its suitable for desulfurization in power plant, serous transmission for fertilizer plants, coking, paper-making such area of strong corrosion of the media. Driven style includes manual, pneumatic, electric, etc.
