Fully Welded Ball Valve is mainly applied for the long distance pipeline transportation of petrol, natural gas and gas pipeline system in cities. Because of the special characteristics of underground type ball valve, the capability to endure pipeline stress, non-corrosbility, safety, weather resisting property and long run reliability is fully considered when designed. There are many various kinds of operation are available included manual, worm gear,pneumatic,electricity,pneumatic-hydraulic,electrically-hydyaulic,computer controlled, as well as various special control models.
