Top Entry Ball Valve – Forged Alloy, API & ISO

Top Entry ball valves are ball valves whose upper part is detachable. The internal components (ball, valve seat, and valve stem) can be maintained or replaced through the top opening without the need to completely dismantle the pipeline. This design is particularly suitable for situations with limited space and frequent maintenance requirements, such as in key fields like oil, gas, chemical, and long-distance pipeline transportation.
