1. Before and after the ball valve is ready. Before and after the pipe should be coaxial, two flange sealing surface should be parallel. The pipeline should be able to withstand the weight of the ball valve, otherwise the pipeline must be equipped with appropriate support.
2. Purge the front and rear pipelines of the valve to remove oil, welding slag and all other impurities from the pipeline.
3. Check the sign of the ball valve and check that the ball valve is intact. Fully open the valve several times to verify that it is working properly.
4. Remove the protective parts on the connecting flanges at both ends of the ball valve.
5, check the valve hole to remove possible dirt, and then clean the valve hole. Even small foreign particles between the seat and the ball may damage the seat sealing surface.
6. Install the valve on the line. Any end of the valve can be mounted on the upstream side. The lever-operated valve can be installed anywhere on the pipe. However, ball valves with gearboxes or pneumatic actuators should be installed upright, ie on horizontal pipes with the drive above the pipe.
7. Install gaskets between the valve flange and the pipeline flange according to the piping design requirements.
8. The bolts on the flange need to be symmetrically, successively and evenly tightened.
9, connecting the pneumatic line (when using pneumatic driver).
10. Operate the actuator to open and close the ball valve several times. It should be flexible and free of stagnation, confirming that it is working properly.
11. Check the sealing performance of the flange joint between the pipeline and the ball valve according to the piping design requirements.
