Flap Valve
Commonly installed at flood walls (levees) or the horizontal outlet ends of connecting pipelines, used for water discharge and preventing backflow from rivers.
Product Overview:
●The flap valve features a circular opening, commonly used for floodwalls (levees) or horizontal
pipeline outlets.
●Suitable for pump stations or water treatment plant discharge, preventing backflow from external
rivers.
●Automatically opens by water flow; closes automatically after shutdown using the valve cover's
own weight.
●Dual-arm structure with self-lubricating bearings ensures durability and reliability.
●The valve cover is robustly constructed to withstand impact forces during closure.
Design Features:
●After pump shutdown, the valve automatically closes when the external water level is approximately
10 cm higher than the internal water level.
●Swing arms have adjustable pivots to limit the rotation angle of the valve cover.
●Equipped with an anti-tilt rod to ensure smooth and stable opening and closing operation.
