Desulfurization butterfly valve

A complete desulfurization system is required in numerous industrial or power fields. At present, the international use is limestone-gypsum wet process, one furnace and one tower desulfurization device, the desulfurization efficiency of this desulfurization device can reach 95.5%. Limestone slurry system after the desulfurization pipeline media will appear strong corrosive, the entire pipeline system and fluid control valves and valve actuators have extremely high requirements. The special butterfly valve for desulfurization is designed and manufactured to meet the special requirements of the desulfurization system.
The desulfurization and denitrification butterfly valve is designed for power plant desulfurization and denitrification projects, fully considering the corrosion and wear of the desulfurization slurry on the valve, ensuring that the valve plate lining is the only part that can come into contact with the slurry, while other parts are not corroded by the limestone (or lime paste) slurry. As a result, the valve body and stem would not need to be made of expensive alloy (2205) materials, resulting in significant cost savings. The unique seat design of the desulfurization butterfly valve completely separates the valve body from the fluid medium. Compared with other similar valves, it has a better way to firmly seat the valve, quick to replace the seat in place, the valve keeps zero leakage, and low friction. The butterfly valve plate is made of high performance alloy (2205) material, which effectively resists the corrosion and wear of slurry.
