1.30 years' service life, no need maintenance, same service life as pipelines.
2. Fully welded valve body structure avoids leakage.
3. Underground valve can be provided to save well digging cost and reduce project upfront investment, ensure the safety of operation and maintenance personnel. 4. Special valve seat with multi-layer sealing structure which guarantees zero leakage. 5.Pressurization prefabricated heat preserving type valve can be provided to avoid the loss caused by the bad heat preserving conditions at site.
