Swing check valves allow flow in one direction, but not both. Swing check valves are also referred to as clack, non-return, stop, check and one-way valves.

The valves and their supporting sinuses, therefore, are developed from the proximal part of the outflow tract, or the "conus" in classical terminology. The initial muscular wall of this distal part of the proximal outflow tract, however, plays no part in the formation of either the valvar leaflets or their supporting arterial sinuses.

A check valve is a kind of automatic valve. It relies on the pressure of the flowing medium in the pipeline to push the valve flap to close and open the valve. When the medium stops flowing, the check valve flap closes, which can effectively prevent the backflow of the medium in the pipeline, which plays a great role in ensuring the safety of the pipeline.

Check Valves Types and Parts. What is a Check Valve? The valve that used to prevent backflow in a piping system is known as a check valve. It is also known as a non-return valve or NRV. The pressure of the fluid passing through a pipeline opens the valve, while any reversal of flow will close the valve.

A check valve is an automatic safety device designed to allow fluids and gasses to flow in one direction and prevent reverse flow. Under pressure, fluids enter the valve at the inlet where they force the disc off the seat of the valve and exit through the outlet. Flow continues steadily as long as the pressure is maintained to keep the disc open.

Common check valve problems are: noise, water hammer, vibration, reverse flow, sticking, leakage, and component wear/damage. To prevent issues, it is crucial that a check valve is specified correctly for the application and media. The two most common issues due to improper specification are reverse flow and water hammer. For both issues, a fast-closing check valve should be used. Reverse flow can occur if the check valve doesn't close fast enough and water hammer can occur if pressure surges occur causing shock waves within the media.
