Precautions
1. Do not allow the check valve to bear weight in the piping system. Large check valves should be independently supported so that they are not affected by the pressure generated by the piping system.
2. When installing, pay attention to the direction of medium flow should be consistent with the direction of the arrow marked on the valve body.
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.
