Check valves (non-return) are installed in pipeline system to allow flow in one direction only. A swing check valve consist of a flap or disc of the same diameter as the pipe bore, which hangs down in the flow path. Check valves produce relatively high resistance to flow in the open position, due to the weight of the disc.
