By rotating the blade normally from 0 to 90°, the flow can be shut off!
The "Double Flap Damper" has a unidirectional operation of the blades, allowing the sealing part to be placed on the outflow side, which helps protect the sealing packing from direct exposure to gas flow and reduces the risk of damage. It is used for backflow prevention, high-seal bypass ducts, and for closing during maintenance. It is suitable for use in gas with high dust concentration. Additionally, since the two blades swing within the casing, it can reduce the face-to-face distance and weight to about 1/2 to 1/4 compared to a single swing valve. 【Features】 ■ High sealing capability ■ Protection of the sealing part from dust in the duct ■ Ability to keep the face-to-face distance narrow ■ Wear resistance measures are possible ■ The reinforcement parts of the blades adopt a structure that minimizes turbulence, ensuring low pressure loss *For more details, please download the PDF or feel free to contact us.
