[purpose of low temperature check valve]

Low temperature check valve refers to the valve that automatically opens and closes the valve disc depending on the flow of the medium itself, which is used to prevent the backflow of the medium. It is also called check valve, one-way valve, reverse flow valve, and back pressure valve. The check valve is an automatic valve. Its main function is to prevent the backflow of medium, the reverse rotation of pump and drive motor, and the discharge of container medium. The check valve can also be used to supply the auxiliary system whose pressure may rise above the system pressure. Check valves are mainly divided into swing check valves (rotating according to the center of gravity) and lift check valves (moving along the axis).
