Lift check valve flow refers to rely on the media itself, and automatically open and close the disc, the valve is used to prevent the backflow medium, also called the non-return valve, check valve, flow valve, and the back pressure valve. Check valve belongs to a kind of automatic valve, its main role is to prevent the backflow medium, to prevent the pump and drive motor reversal, and the discharge of the container medium. Check valve can also be used to give the pressure could rise to more than the system pressure of the secondary system supply piping. Main can be divided into swing check valve check valve (in accordance with the center of gravity rotating) and lift check valve () along the axis.
