1. The front and rear pipes should be coaxial, and the sealing surfaces of the two flanges should be parallel. The pipe should be able to withstand the weight of the Carbon Steel Wafer Ball Valve Body, otherwise the pipe must be equipped with appropriate support.
2. Purge the pipeline before and after the valve to remove oil, welding slag and all other impurities from the pipeline.
3. Check the sign of the Stainless Steel Wafer Ball Valve Body and find out that the ball valve is intact. The valve was fully opened and closed several times to confirm that it was working properly.
4. Remove the protective parts on the flanges at both ends of the ball valve.
5. Inspect the valve hole to remove any possible dirt and then clean the valve hole. Even small particles of foreign matter between the seat and the ball may damage the seat sealing surface.
