The baffle valve serves as the bridge connecting the boiler and desulfurization system, significantly impacting the boiler's operation and the lifespan of the desulfurization system. Primarily used in the inlet, outlet, or bypass ducts of flue gas desulfurization system absorption towers, it isolates flue gas flow and can also be applied to other ducts with high operational isolation requirements. The baffle valve plays a crucial role in ensuring the normal and stable operation of the boiler and desulfurization system, as well as the safety of the system equipment.

To fundamentally reduce the pollution of nitrogen oxides and sulfur dioxide in the atmosphere, prevent the emission of harmful gases into the air, and protect public health and the ozone layer, the desulfurization and denitrification process cannot be overlooked. The insertion valves used for desulfurization tower maintenance must also meet certain requirements, including corrosion resistance, wear resistance, smooth operation, long lifespan, and good sealing. Zhongsheng Environmental Protection has researched a smoke channel external damper valve for the opening of the baffle valve to reduce smoke resistance and extend the service life of the baffle valve. Based on the principle of metal density, a special material with soft and hard double sealing is used to seal the plug valve, achieving an air tightness of over 99%. The electric hydraulic drive method is resistant to high temperatures, and the switch will not deform or stick.
