Fully welded ball valve also called Welded Body Ball Valve, as the body is fully welded. The fully welded body ensures that no external leakage path from valve body. All welding processes are qualified and performed according to ASME Section IX. The welding for the valve body are to performed with Non-destructive tests.

We manufacture fully welded trunnion ball valve, side entry construction; also customized fully welded ball valve or similar to cameron fully welded ball valves, especially cameron t31 fully welded ball valve design.

Once fitted the valve is turned 90°, the valve opens or closes. When the valve is open the ball's, hole is in line with the flow direction and closes when it is turned 90° by either a manual handle or by actuation. When the valve is open the lever handle should align with the pipe or flow and is perpendicular to the pipe when it is closed. This makes it easy to determine the position status of the valve.

As the ball opens and closes between the seats, they offer a wiping motion and clear suspended particles from the surface of the ball. It must be said that abrasive solids will damage the seats and the surface of the ball which will eventually cause leakage. Solid, stringy and fibrous material may prevent the ball from closing. The most common ball valve design is two way, which enables flow to travel from the inlet to the outlet. Three and four-way ball valves enable flow to travel in multiple directions.
