H44H Swing Check Valves are designed to prevent backflow of media within pipelines. The lifting and closing elements open or close automatically with the flow of media and force, serving as check valves to prevent backflow. Check valves are classified as automatic valves, primarily used on pipelines with unidirectional media flow, allowing media to flow in only one direction to prevent accidents.
