Fully Welded Ball Valve

Extended Stem Balal Valve

LF2 Cryogenic Extended Stem Extend Spindle ball valve

Features & Benefits

1. Fully Welded Ball Valve (welded body ball valve) gives it maximum strength at minimum weight as well as maximum resistance both to pipeline pressures and stresses.
2. The compact, spherical design also eliminates body flanges, thus reducing overall size and leak paths.
3. Fully Welded Ball Valve (welded body ball valve) are ideal for buried service applications to decrease potential leak points and reduce the potential of fugitive emissions from flanges.
4. Typical for underground and buried installation.
5. Various testing procedures are used to confirm the tightness of the entire ball valve.       

Extend Spindle LF2 5A02 Cryogenic Fully Welded Ball Valve

Heating Supply BW Fully Welded Ball Valve

Features & Benefits

1. Fully welded body construction
2. Sealing options in self relief or double piston effect , or a combination of both (DIB2)
3. Extended stem for underground burried service
4. Anti-blowout stem design
5. All welding processes for the body are suited to the materials of construction and are qualified and performed according to ASME Section IX
6. Non-destructive tests (NDTS) are performed per ASME VIII Division 1, App. 12 on the circumferential weld joints of the body

Butt Welded Ball Valve

Butt Welded Ball Valve

Features & Benefits

1. The body utilizes forgings, which are available in a large array of materials, making the fully welded ball valve (welded body ball valve) well-suited for special applications as well as standard service.
2. All welding processes for the body are suited to the materials of construction and are qualified and performed according to ASME Section IX.
3. The floating seats are free to move slightly along the longitudinal axis of the bi-directional valve.
4. Double Block-and-Bleed – A single valve with two seating surfaces that, in the closed position.
5. Double Piston Effect (DPE) Seat Design - The seat design allows for both seats to seal with pressure acting from the same side of the valve.

What Is A Fully Welded Ball Valve?

Fully welded ball valve is widely used in various fields. Its superior quality and high-performance stability are beyond the reach of ordinary cast steel ball valve. Its service life is far longer than cast steel ball valve.

What Are The Applications Of Fully Welded Ball Valve?

Fully welded ball valve is widely used in urban gas, urban heating, petrochemical, shipbuilding, steel, regulating station, power plant and other kinds of pipeline equipment.

What Are The Advantages Of  Fully Welded Ball Valve?

Fully welded ball valve can be operated and used reliably for a long time.   It needs maintenance and is easy to install.  The installation of the valve is more convenient.  The driving mode of Fully welded ball valve is manual, worm gear, pneumatic or electric.    Fully welded ball valve is generally connected by butt welding.
