Flap gates operate with even a small amount of water during drainage, and they respond sensitively and smoothly to differences in water levels inside and outside. They are required to maintain sufficient strength and functionality to prevent backflow. Additionally, designs and colors that match the environment are becoming increasingly 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, and it automatically opens and closes based on the water level difference, making it a valuable tool for backflow prevention gates.
