The low temperature check valve refers to a valve that automatically opens and closes the valve flap depending on the flow of the medium to prevent the medium from flowing backward. Check valve belongs to an automatic valve, and its main function is to prevent the medium from flowing backward, to prevent the pump and the drive motor from reversing, and to release the container medium. Check valves can also be used to supply lines to auxiliary systems whose pressure may rise above the system pressure. Check valves can be mainly divided into swing check valves (rotating according to the center of gravity) and lift check valves (moving along the axis).
