Fully Welded Ball Valves

Thoroughly-Tested Fully Welded Ball Valves

Applied in extreme working conditions, such as in natural gas, urban heating, and long-distance pipelines, fully-welded ball valves are bound over the whole cross-section to overcome higher loads. As such, stress corrosion cracking and external contamination are actively averted to increase the service life of our valves.


DomBor Valve’s supply network and third-party 3C laboratories help us produce fully welded valves that follow industry regulations. Our valves, which come in front welding, middle welding and side welding seam types, have an economical design that can save you a lot of money in the long run. To ensure tightness, we conduct ultrasonic and hardness tests to determine the strength and durability of our valves.

The Lowest-Cost Strategy Is To Choose Reliable DomBor Valves.

DomBor Valve, with its experienced specialists, specializes in manufacturing industrial valves and provides technical support and one-stop solutions for the global market.

Fully Welded Ball Valves

Dombor is one of the leading fully welded ball valve manufacturers. A fully welded ball valve is a valve, the body of which does not contain any nuts or bolts, which ensures zero leakage from the body as the body of the valve is fully welded. We design the valve’s body in such a manner that the thickness of the valve helps avoid the cavities from shrinking and helps prevent even the minimal holes or cracks.

Structure Of Fully Welded Ball Valve

Fully welded ball valves come in various structures; the structures of a fully welded valve can either be cylindrical or spherical. In the case of a spherical welded valve, the body contains only one seam, which is welded, while in a cylindrical valve, two seams are welded.


The torque of a welded body ball valve is small, while the structure of the valve is tight. The packing is such that there are low or zero emissions from the body and is also fire safe; the lifespan of such a valve can go up to 30 years. The machine’s combination is made so that the machine ensures a higher strength with a very low weight. These are generally used for the transmission of gas and oil.

Why do you need a fully welded ball valve?

Fully Welded Ball Valves are the most commonly used for onshore petrochemicals and offshore petrochemicals. These valves are manufactured so that they can withstand high pressure and high temperature, because of which the valves are versatile.


Many industries use these welded ball valves because of their zero leakage performance. The shape of the valve is retained even after being exposed to chemicals and higher temperatures.
