Yantai Tae Merrill Lynch in response to national environmental policy, the policy of the desulfurization plant a series of environmental protection measures implemented, the company for power plant desulfurization systems application environment, focused research and development of stainless steel ceramic ball valve, stainless steel housing so that the whole valve durability, corrosion resistance and other characteristics of the ceramic lining inside the valve, all parts are in contact with the media structure of ceramic materials, their chemical stability and high hardness (Rockwell hardness of HRC90), second only to diamond. Therefore, this valve has a very high resistance to abrasion, corrosion, erosion resistance, and good heat insulation, thermal expansion of small, widely used in power plant flue gas desulfurization system, bottom ash handling system and combustion system; soda brine system, distillation system; pulp mill control system
