Underground buried fully welded ball valves features:

1. The whole buried fully welded ball valve is weled. In the production process, there is a strict testing process. Such as ultrasonic non - destructive inspection of forged materials and seepage inspection of welded joints.

2.The buried fully welded ball valve can be trunnion mounted type and floating type.For large diameter buried fully welded ball valves, usually use trunnion mounted type, because for the same size ball valves, trunnioin type ball valves have the smaller torque than floating type ball valve.

3.Because the buried fully welded ball valve needs to be operated on the ground, so it should be installed extension stem.The length of the buried fully welded ball valve stem should be depends on the working conditions or customer requirements.
