The KVD 200–630 flap valve installs in piping systems to prevent backflow, such as at outlets to channels or pump stations. Its 15° inclined flap with a robust rubber hinge provides low hydraulic resistance in flow direction while ensuring reliable closure in case of backflow. Made of corrosion-resistant materials, it requires minimal maintenance and allows straightforward installation.
