Which is better between welded ball valves and flanged ball valves

To distinguish between welded ball valves and flanged ball valves, it depends on the on-site working conditions. Welding ball valve maintenance is certainly not as convenient as flange ball valve maintenance, but sometimes pipelines can only be welded on site.
Technical characteristics of welded ball valves:
1. The valve body structure is welded as a whole, without external leakage.
2. The valve seat is composed of PTFE sealing rings and springs, which have strong adaptability to pressure and temperature changes and will not produce any leakage within the range of use.
3. The anti leakage structure of the valve stem, with one PTFE self sealing gasket and one O-ring at the bottom of the valve stem, consisting of two O-ring seals and two PTFE gaskets, ensures no leakage.
4. The valve body material is the same as the pipeline material, and there will be no uneven stress or deformation due to earthquakes or vehicles passing through the ground.
5. The valve body is light and easy to insulate.
6. Directly buried ball valves can be directly buried underground, without the need to build large valve wells. Instead, small shallow wells need to be installed on the ground, greatly saving construction costs and time.
7. The length of the valve body and the height of the valve stem can be adjusted according to the construction and design requirements of the pipeline.
8. The machining accuracy of the sphere is very precise and easy to operate, without any adverse interference.
There are two connection methods: welding and flange.
11. Operation mode: handle, gear (vertical/horizontal)
