Top Entry Trunnion Mounted Ball Valve

Top entry trunnion mounted ball valves are widely used in petroleum and natural gas pipelines, as well as in oil extraction, oil refining, petrochemical, chemical, chemical fiber, metallurgy, electric power, nuclear power, food, and paper making equipment. The top entry trunnion mounted ball valve is easy and quick to disassemble on the pipeline, and the maintenance is convenient and fast. When the valve fails on the pipeline and needs to be repaired, it is not necessary to remove the valve from the pipeline. It is only necessary to remove the middle flange bolts and nuts, remove the bonnet and stem assembly from the valve body together, and then remove the ball and valve Block assembly. You can repair the ball and valve seat online. This maintenance saves time and minimizes losses in production.
