Top Entry Ball Valve

Top entry ball valve is widely used in oil and gas pipelines, as well as in equipment of oil recovery, oil refining, petrochemical, chemical fiber, metallurgy, electric power, nuclear power, food and paper. The top entry ball valve is easy disassemble on the pipeline, and it can be maintained conveniently and quickly. When the valve was broken, it is not need to remove the valve from the pipeline. It only need to remove the flange of bolts and nuts which between body and bonnet, and take out ball and seat assembly to repair. This valve structure not only save maintenance time,  but also reduce losses in production.
