Features:
1. Full welded ball valves are widely used in natural gas, oil, heating, chemical and thermoelectric pipe network and other areas of long-distance pipelines.

2. Sealing carbon reinforced PTFE seals negative pressure elastic slope on the sphere, so that seal zero leakage, long life and so on.

3. The valve compact, light weight, easy to heat, easy to install.

4. The main advantage is that it is almost no leakage phenomenon.
