Fully welded ball valve, the valve body is welded by steel pipe, there will be no external leakage and other phenomena. 2. The processing of the ball has advanced computer detector tracking detection, so the processing accuracy of the ball is high. 3. Because the valve body material is the same as the pipeline material, there will be no uneven stress, nor will there be deformation due to earthquake and vehicle passing through the ground, and the pipeline is resistant to aging. 4. The sealing ring body is made of RPTFE material with 25%Carbon(carbon) to ensure complete no leakage (0%). 5. Directly buried welded ball valve can be directly buried in the ground, there is no need to build a large valve well, just set a small shallow well on the ground, greatly saving construction costs and engineering time. 6. The length of the valve body and the height of the stem can be adjusted according to the construction and design requirements of the pipeline. 7. The processing precision of the ball is very precise, the operation is light, and there is no bad interference.
