Top Entry Ball Valve

Top entry ball valve is a special valve, valve design structure is different with side entry. Its main function is to distribute and regulate the flow direction of the medium.The valve body adopts an integral design. The valve body of the ball valve is installed and disassembled from the top. The valve body is an integral type, and the ball and the valve stem are installed from the top. The working principle is that the ball rotates 90° around the axis of the valve stem to achieve opening and closing. The upper structure is convenient for maintenance. The core feature of this valve lies in the fact that its internal parts can be inspected and repaired without disassembling the pipeline. It is convenient for maintenance and has reliable sealing, making it suitable for working conditions that require frequent maintenance. It is mainly applied to pipeline systems in industries such as petroleum, chemical engineering, and natural gas, especially suitable for underground pipelines, space-limited or inconvenient maintenance scenarios. It can achieve pressure maintenance and reduce downtime losses.
