Swing check valve| The one-way valve

SWING Check Valve is a non-return valve, a one-way valve, that is mounted on a disc operating on a hinge. When the liquid hits the disc, it opens or closes according to the pressure of the flow. Working without any power or external control, the check valve allows water to flow only in one direction. Once the flow stops, the disc swings back to block the water flow in the counter direction. If backflow is a problem, a SWING check valve will solve this problem, transporting fluids in one direction. The flush-toilet mechanism is the most popular application of the SWING Check Valve.
