Customized hydraulic flap gates and customized hydraulic automatic flap gates (commonly known as "movable dams") are suitable for industries such as urban flood control, environmental beautification, irrigation, power generation, power supply, and tourism. They are applicable for regulating water levels in the upper reaches of small and medium-sized rivers, especially for construction in mountainous streams and rivers where floods rise and fall sharply, and where power supply and transportation are inconvenient.

Their function is to serve as "movable" water-retaining structures, replacing fixed weirs or lowering the height of overflow weirs. this effectively regulates the reservoir capacity, thereby reducing flood inundation losses and sedimentation upstream of the dam.

these customized products boast advantages such as wide practicality, simple structure, low cost, and significant economic benefits, opening up broad prospects for the comprehensive utilization of water resources.
