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.

Specit fications

Didtek Fully Welded Ball Valve have been designed with welded body, including two welding line and one welding line, floating mounted ball and trunnion mounted ball. This type of valves are mainly used Natural gas , without any leakage from body outside.
