  • fan shaped radial vane louver damper valve

    one way check butterfly damper valve is used for the ventilation duct of flue gas and other gases. Its main function is to prevent the backflow of the medium. The function of the check valve is to allow the medium to flow in only one direction and prevent the flow in the opposite direction. Usually, this valve works automatically. Under the action of fluid pressure flowing in one direction, the valve disc opens; When the fluid flows in the opposite direction, the fluid pressure and the self weight of the valve disc act on the valve seat, so as to cut off the flow.
