Top entry ball valves are valves that assembled its ball from top side part. It just like a globe valve that has body and bonnet except the trim part utilize a ball type. It comprises a one single body. Usually top entry ball valves are made from casting metal.
Since it made from casting it will need some additional NDE test to make sure that there is no defect from the casting process. The top entry ball valves usually used at an application that require a minimal disassembly for in-line maintenances of its internal parts. Therefore it’s very common to use top entry ball valves at high pressure application that require in-frequent maintenances such as HIPPS (High Integrity Pressure Protection System) valves etc. The advantages of the top entry ball valves is its construction that allow minimal thread connection so that it will also minimize possible leak path.
Content
Top entry ball valve is designed according to API 6D. The one-piece body design ensures that it has enough strength and rigidity under the maximum rated working pressure. And the top entry structure has the online maintenance advantage.
