Fully welded ball valve advantages:
1. Integral seamless steel tube pressed full-auto welded without leaking outward.
2. PTFE+25% carbon fiber and disc spring feely compensating structure zero leakage.
3. Directly buried without need of a high ground well, saving the engineering cost.
4. Both valve and pipeline are made of the same material, without the condition of uneven stress.
5. Multiple connection combination, fire and electrical prevention design, using in the special
Working conditions.
