Single-leaf check lobe valve is designed to prevent reversal of direction of working medium flow in the pipeline. Working principle. Under the action of the direct flow of the working medium, the locking flap rises, opening the passage opening. When the pressure drops, the dead weight of the flap returns it to its original position, closing the passage opening and preventing the flow of medium in the opposite direction.
