Helpful Advice
  • 1.

    Before installation, carefully check whether the mark is consistent with the use requirements.

  • 2.

    During installation, dust and debris in the valve cavity and pipeline should be removed to avoid    affecting the sealing performance.

  • 3.

    The threaded part of the valve stem should be kept well lubricated during operation.

  • 4.

    Valves that have not been installed and used should be stored in a dry room and stacked    neatly. Open-air storage is not allowed to prevent damage and rust.
