Advantages:

1. integral seamless steel tube pressed full-auto welded without leaking outward. 

2. PTFE+25% carbon fiber and disc spring freely compensating structure zero leakage. 

3. can be 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. in multiple connection combination, for use with special working conditions.
