Casting Trunnion Ball Valve

Middleeast valve is the leading Casting Trunnion Ball Valve Supplier in Saudi Arabia. We supply to cities like Riyadh, Jeddah, Taif, and Tabuk. A Casting trunnion ball valve is named after its unique design, where the ball within the valve is supported by trunnions, which are small shafts that extend from the sides of the ball. These trunnions allow the ball to pivot within the valve body, controlling the flow of the fluid or gas.

The primary function of a casting trunnion ball valve is to regulate the flow of fluids or gases in a pipeline. By turning the valve handle or actuator, the ball inside the valve can be rotated to either allow or block the flow. When the ball’s hole is aligned with the pipeline, the valve is open, allowing the fluid or gas to pass through. When the ball is rotated to a position where the hole is perpendicular to the pipeline, the valve is closed, preventing the flow.

Middleeast valve is a topmost Casting Trunnion Ball Valve Supplier in Saudi Arabia and consists of a hollow spherical ball with a hole (bore) through its center. The ball is positioned within a valve body, which also has two or more ports for fluid or gas to enter and exit. The ball is connected to trunnions on either side, which allow it to rotate within the valve body. When the valve is open, the ball’s hole is aligned with the pipeline, enabling flow. When closed, the ball is rotated to block the flow.
