Features and Benefits

Both types of valves, full welded and three pieces trunnion ball valves, offer reliable performance and are commonly used in various industries. Discover the main difference between them:

- Full Welded Three Pieces Trunnion Ball Valve: The full welded construction eliminates potential outer leak paths, making it suitable for applications requiring absolute leak-tightness, such as critical process control or pipelines carrying hazardous fluids. It also offers enhanced structural integrity and resistance to external forces.

- Three Pieces Trunnion Ball Valve: The three pieces design allows for easier maintenance and repair, as the valve can be disassembled by removing the bolts connecting the body, bonnet, and ends. This feature is beneficial when component replacement or inspection is required.

The choice between them depends on specific application requirements, such as the need for absolute leak-tightness, ease of maintenance, and system design considerations.
