Forged Fully Welded Ball 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.
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.
