Five 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. can be directly buried without need of a high ground well,saving the engineering cost.
4. both valve and pipeling are made of the same material, without the condition of uneven sterss.
5. in multiple connection combination, for use with special working conditions
This series of products sealing performance, reliable, maintenance-free for 20 years, can be installed in needs to be buried or carts through the pipeline for the off-road by lengthening the stem , operating lever can be achieved through a dedicated vertical distance ground operation of the valve switch, easy to use saving maintenance costs, protect the personal safety of operating personnel. The main use of natural gas mains, branch pipelines, city gas compressor stations, gas pipelines, gas equipment for urban heat main branch pipelines.
