Fully Welded Ball Valve for Heating Pipeline
Features
1. Fully welded valve body structure avoids leakage.
2. 30 years' service life, no need for maintenance and same life expectancy with pipelines.
3. Specially valve seat with muiti-layer sealing structure that guarantees zero leakage.
4. Underground valve can be provided to save well making cost and reduce preliminary project investment, and ensure the
safety of operation and ma intenance personnel.
5. Over-pressurized prefabricated heat preserving valve can be provided which ffectively prevents defects caused by bad heat-
preserving conditions at site.
