Precautions for storage, installation and use

1. This valve is kept in a dry warehouse, and is strictly prohibited to be stored in the open air.

2. Long-term storage should be maintained regularly.

3. The product can be installed in any position and any pipeline, and the working conditions should be consistent with the requirements in the performance specifications.

4. Before installation, the pressure test should be carried out to meet the requirements before installation.

5. The pipe and valve cavity should be cleaned before installation.

6. After installation, the product shall not be subjected to a large external force.

7. The direction of the handle should be consistent with the direction of the square groove of the stem.

8. When the local minimum temperature is lower than 4℃, insulation protection should be done; As the end valve, it should be heated with a pipe or jacket to prevent the temperature of the pipe wall from falling below 0℃.

9. It is strictly prohibited to install and use in the pipeline under vibration or rapid changes in medium temperature.
