Product Details

Lift check valve to the clamp is refers to the flow depend on the medium itself, and automatic opening and closing valve, used to prevent the backflow medium valve, also known as the non-return valve, check valve, valve, and the back pressure valve upstream. 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. This valve shall generally be installed in the pipeline.
