    Tips: What should pay attention to when using a brass ball valve?

    Preparation before installation
    1. The front and rear pipelines of the brass ball valve are ready. The front and rear pipes should be coaxial, and the sealing surfaces of the two flanges should be parallel. The pipeline should be able to bear the weight of the ball valve, otherwise the pipeline must be provided with proper support.
    2. Purge the pipelines before and after the valve to remove oil, welding slag and all other impurities in the pipeline.
    3. Check the mark of the brass ball valve to find out that the ball valve is intact. Open and close the valve several times to verify that it is working properly.
    4. Remove the protective pieces on the connecting flanges at both ends of the brass ball valve.
    5. Check the brass ball valve hole to remove possible dirt, and then clean the valve hole. Even small particles of foreign matter between the seat and the ball can damage the seat sealing surface.
    1. Install the ball valve on the pipeline. Either end of the valve can be installed on the upstream end. The handle-actuated valve can be installed anywhere on the pipeline. However, ball valves with gearboxes or pneumatic drives should be installed upright, i.e. on a horizontal pipeline, with the drive above the pipeline.
    2. Install a gasket between the valve flange and the pipeline flange according to the pipeline design requirements.
    3. The bolts on the flange should be tightened symmetrically, sequentially and evenly.
    Post-installation checks
    1. Operate the driver to open and close the ball valve several times, and it should be flexible and not stagnant, confirming that it works normally.
    2. Check the sealing performance of the flange joint surface between the pipeline and the ball valve according to the pipeline design requirements.
