Flap gates operate with even a small amount of water during drainage and respond sensitively and smoothly to differences in water levels inside and outside. They are required to maintain sufficient strength and functionality during backflow prevention. Additionally, designs and colors that match the environment are increasingly being highlighted as important factors for future gates. The "Aluminum Alloy Cast Flap Gate AGF Series" is installed at the end of drainage pipes (inlets) in rivers and flood walls for internal drainage purposes, automatically opening and closing due to differences in water levels, making it a valuable tool for backflow prevention gates.
