The check valve is a valve that constantly maintains fluid flow in a constant direction and prevents reverse flow. The disc is pushed open by the fluid pressure, but when it flows backward, the disc is brought into close contact with the seat of the body by the back pressure to prevent backflow. There are three typical types of check valves

Swing Check valves are used where the flow moves through the valve in approximately a straight line similar to that in a gate valve, is commonly used in pipe 

The swing check valve functions by allowing flow forces to move the closure element, it is a hinged clapper which swings or rotates around a supporting shaft. The disk swings away from the valve-seat to allow flow in the forward direction, and returns to the valve-seat when upstream flow is stopped, to prevent backflow.
