Our company's flue gas flapper valve adopts foreign advanced technology, absorbs the advantages of domestic and foreign products of the same industry, combines the usage experience and feedback information of many users, and independently innovates and develops a new generation of flue gas flapper valve. Its principle is to use the latest hydraulic technology to drive the flapper to extend and retract back and forth to achieve the purpose of isolating flue gas.                           

Flue gas flapper valve is mainly used in the inlet and outlet of the absorption tower or bypass flue of the flue gas desulfurization system to isolate the flue gas circulation. It can also be used in other flue gas ducts with high operation isolation requirements.

Our company's Electric hydraulic plug-in valve has won the national patent technology (patent number: ZL201320784346.6). Since its launch, the product has been recognized and praised by many owners. PetroChina, Sinopec, China National Chemical Corporation, China Resources Group, Huadian Group, Shanmei Group, China Coal Group and other companies have repurchased our gate valves several times. They all agree that the new baffle valve produced by our company is flexible in switching, has excellent sealing performance and reliable quality, and solves the technical problems commonly found in traditional products.

Advantage：

• It is driven by hydraulic method and has high stability.
• It does not deform at high temperatures and does not collect ash.
• When working normally, the switch is flexible, without sticking and with little resistance.
• The operation is simple and the installation period is short, and it can be completed within the minor maintenance period.
• Long service life, basically no maintenance required after one installation, and low operating cost.

After closing, there is no internal leakage, external leakage, good sealing, and no air leakage or wind leakage.
