Flap valves in welded steel are manufactured according to a simple as well as very reliable construction to grant a one-way direction of flow. The main purpose of flap valves at the end of a pipeline is to discharge water while preventing back up of water in the pipe. Flap valves have many advantages: good resistance to corrosion, weather conditions, thermal shock and mechanical stress. They are easy to be installed and don’t need any maintenance.
