The check valve is a self-actuated non-return valve which is designed to prevent backflow. Fluid flowing in the required direction opens the valve, while reverse/backflow reseats the piston or disc/flapper, closing the valve and preventing flow in the opposite direction. There are two main types of check valve, the piston check valve and the swing check valve.
