1. Fully welded ball valve, free from external leakage, etc. The machining process of the sphere is tracked and detected by a computer detector, so the machining accuracy of the sphere is high.

2. As the valve body material is the same as the pipe material, it will not have uneven stress, nor will it deform due to earthquake and when vehicles pass the ground. The pipe is aging resistant.

3. The seal ring body is made of RPTFE material containing 25% Carbon to ensure no leakage (0%).
