The Function Of a Check Valve
Check valve is also called clack valve, one-way valve, or non-valve valve because it only allows fluid to flow in one direction. These industrial valves are automatically activated by the force generated by the flow of the medium in the pipeline and can be classified as automatic valves. The check valve is used in the pipeline system, and its main function is to prevent the backflow of the medium, prevent the pump and its generator from reversing, and prevent the backflow of the medium from the container. This check valve can also be used to replace the auxiliary system at which the pressure can increase above the pressure of the main system. If the fluid flows back and the check valve is not installed, a water hammer may occur. Water hammer often occurs, with excessive force, and it is easy to damage the pipeline or components. Check valves can be used in a variety of applications ranging from pipelines to gas export facilities.

What Is a Check Valve?
Check valves are usually installed in the pipeline to prevent backflow. A check valve is basically a one-way valve in which the flow can flow freely in one direction, but if the flow turns, the valve will be closed to protect the piping, other valves, pumps, etc. If the flow is diverted without a check valve installed, a water hammer may occur. Water hammer often occurs with extreme force and can easily damage pipes or components.
Precautions when choosing a check valve
When selecting a check valve, it is important to conduct a cost-benefit analysis of the specific system. Usually, the focus is on reducing costs while obtaining the lowest possible pressure loss, but for check valves, higher safety equals higher pressure loss. Therefore, in order to ensure the check valve protection system, each system needs to be evaluated separately, and factors such as the risk of water hammer, acceptable pressure loss, and the financial consequences of installing a check valve must be considered.
