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. It allows full unobstructed flow and automatically shuts as pressure decreases. The exact operation will vary depending on the mechanism of the valve.

Check valves shall be provided as required in transfer systems to prevent backflow and shall be located as close as practical to the point of connection to any system from which backflow might occur.

Swing check valves work a little like a butterfly valve. They have a disc inside that covers the opening of the valve. That opening has to be clear in order for anything to pass through. The disc is attached to a hinge, so the disc can swing open or closed when liquid hits the disk. It's kind of like a circular door. The direction of the flow is the most important thing when using these valves.

When liquid or gas is traveling in the desired direction, the pressure of the flow pushes the door open, allowing liquid or gas to pass through. When liquid or gas travels in the wrong direction, the opposite happens. The force of gas coming back through the valve pushes the disc against its seat, closing off the valve. When installing a swing check valve, it is vital that it opens when liquid is passing through the desired direction.
