2. Lifting spring check valve should be installed on the vertical pipeline.

3. Visual inspection must be carried out before valve installation.

4. The installation position, height, and direction of inlet and outlet must meet the design requirements. Note that the direction of medium flow should be consistent with the direction of the arrow marked on the brass spring check valve body, and the connection should be firm and tight.
