1. Fully welded ball valve, there will be no external leakage and other phenomena. The processing of the ball body is tracked by advanced computerized detectors, so the ball body is processed with high precision.

2. As the valve body material is the same as the pipe material, there will be no uneven stress, and no deformation due to earthquakes and vehicles passing through the ground, and the pipe is resistant to aging.

3. The sealing ring body is made of RPTFE with 25% Carbon content, which guarantees no leakage (0%).
