100% Original Factory China Soft Sealed Casting Ots/OEM Ductile Iron Flange Swing Check Valve

Short Description:

In air pollution, sulfur dioxide is an important pollutant, and more than 60% of sulfur dioxide pollutants come from industrial flue gas emissions. With the gradual improvement and improvement of China’s environmental standards, as well as the improvement of national environmental awareness, China’s future projects with industrial flue gas emissions must be desulfurized. Valves are one of the most important components in flue gas desulfurization equipment. The requirements for desulfurization valves are not only resistant to chloride, oxide and acid, but also to severe abrasive wear and mud corrosion. Correct selection of valve material and structure and prolonging the service life of the valve are the key to the flue gas desulfurization valve.

Always adhere to the best design principles, fully considering the corrosion and wear of desulfurization slurry on the valve, to ensure that the valve plate lining is directly able to contact the slurry components, while other components are not corroded by limestone (or limestone) slurry. Therefore, the valve body and stem do not need to use expensive alloy (2205) material, thus greatly saving costs.
