Function
The Top Entry Ball Valve is designed for on/off control and flow regulation in industrial piping systems. The top-entry design allows for easier access to the valve’s internals, facilitating quick repairs, maintenance, or part replacement without the need to remove the entire valve from the pipeline.
The ball valve uses a rotating ball to control the flow of fluid. When the ball is turned 90°, it either opens or closes the passage for fluid. The full-bore design ensures that when the valve is open, there is little to no pressure drop, maximizing the flow efficiency. The valve’s seat design ensures a tight seal, preventing leaks and maintaining pressure integrity even under high-pressure conditions.
Made from stainless steel, carbon steel, and alloy materials, the valve offers superior corrosion resistance, durability, and performance under demanding conditions. The full-bore design ensures minimal flow resistance and allows for unrestricted fluid passage, making this valve suitable for large flow capacity and high-pressure applications.
