Full Diameter Full Welded Ball Valve Carbon Steel, Stainless Steel
The whole structure of the all-diameter all-welded ball valve adopts the all-welded industrial structure, so that the inner and outer seal of the valve has been greatly improved, the weight of the valve has been greatly reduced (especially DN300 caliber below) so that the installation of the valve becomes more convenient, not only reduces the cost of engineering construction, but also saves time. All-welded ball valves are widely used in urban gas underground pipelines, natural gas transmission pipelines, pressure regulating stations and other fields.

Full diameter full welded ball valve features
1, the valve body adopts seamless steel pipe pressing forming.
2, the overall structure of the valve adopts the welding manufacturing process to reduce the external leakage; Valve weight greatly reduced, more convenient installation.
3, the elastic washer and carbon fiber reinforced sealing ring, can handle tens of thousands of reciprocating movement without leakage, to ensure the service life of the valve.
4, the seal of the valve can be used continuously under the condition of -40℃-200℃ without failure.
5, the connection methods are butt welding, flange, thread connection and other forms, open by handle, worm gear drive, electric and other ways.
6, long rod directly buried welding ball valve can be deeply buried underground, no need to set the valve well, the operator only needs to operate on the ground with a handle or worm gear drive mechanism, very convenient.
