Category and Installation Precautions of Check Valve
2020-11-15

Check valve refers to the valve that automatically opens and closes the valve disc according to the flow of the medium itself. The check valve is an automatic valve whose main function is to prevent backflow of media. Check valve can be divided into Wafer Check Valve, Lifting Check Valve and Swing Check Valve.

The check valve can be applied to various medium pipelines according to different materials. The working characteristics of the check valve are that the load changes greatly and the opening and closing frequency is small. Once in the closed or open state, the pot life is long without moving parts.


Check valve installation precautions:

1. The lift-type vertical disc check valve should be installed on the vertical pipeline.

2. The lift-type horizontal disc check valve should be installed on the horizontal pipeline.

3. During installation, the flow direction of the medium should be consistent with the direction of the arrow marked on the valve body.

4. The check valve should not bear weight in the pipeline. Large check valves should be independently supported from the pressure created by the piping system.
