Fully Welded Ball Valves

Fully welded ball valve is one of the most commonly used valves in the petroleum industry. The distinctive design of the valve increases strength while reduces weight as well as increases resistance to pressure and stress on the pipeline. The ball valve combines the strength of forged components with a lightweight and compact spherical design. The compact, spherical design also eliminates body flanges, reducing overall size and potential leak paths further.

Fully welded ball valve is mainly used in gas transmission and distribution pipeline (mid-stream), especially for underground and buried installation.
