Suggestions on Installation and Maintenance of Lift Check Valve
2022-08-24

Lift check valve refers to a valve that automatically opens and closes the valve disc depending on the flow of the medium itself to prevent the medium from flowing backward. The function of the check valve is to only allow the medium to flow in one direction and prevent the reverse flow.


Installation and Maintenance of Lift Check Valve

1. Both ends of the passage of the lift check valve must be blocked and stored in a dry and ventilated room. If it needs to be stored for a long time, please check whether there is rust and corrosion every day.

2. Before installation, the valve should be cleaned and the defects caused during transportation should be eliminated.

3. Before installation, please carefully check whether the marks and nameplates on the valve meet the use requirements.

4. The lift check valve shown in above picture can only be installed on the horizontal pipeline.

5. When installing the check valve, pay attention to the flow direction of the medium. The flow direction of medium should be consistent with the arrow direction indicated on the valve body.
