Check Valve Its main function is that the water hammer pressure is very small, the valve disc stroke is short, the valve disc is light, it has spring-assisted closing, and the valve closing speed is very fast. The structure length is very short, the volume is small, and the weight is very light, which brings great convenience to the installation, transfer, storage and pipeline arrangement of the valve, and can save a lot of materials and reduce the cost.
The installation of the check valve should pay attention to the following matters:
1. Do not let the check valve receive weight in the pipeline. Large check valves should be supported independently so that they are not affected by the pressure generated by the pipeline.
2. When installing, pay attention to the direction of the medium flow should be the same as the direction of the arrow marked on the valve body.
3. Lifting vertical disc check valve: should be installed on a vertical pipeline.

3. The lift type vertical flap check valve should be installed on the vertical pipeline.
4. The lift type horizontal flap check valve should be installed on the horizontal pipeline.
