There is provided, in one embodiment, a ball valve for regulating the flow of petroleum fluids therethrough. The ball valve is capable of transitioning between an open and a closed position. The ball valve includes a lower cage and an upper cage. A common cage channel runs between the upper and lower cage and can be aligned along a central cage axis. Petroleum fluids can pass through the cage channel. The lower cage also includes an annular wall disposed thereon and a ball seat positioned on the lower cage. A ball disposed in the valve can position itself off and on the ball seat in order to open and close the valve. The upper cage, which attaches to the lower cage, defines a plurality of apertures; as petroleum fluids pass through the apertures, the apertures impart a cyclonic rotation on the fluid. A chamber wall is also connected to the upper cage, the chamber wall defining a ball retaining chamber. The ball rests in the ball retaining chamber when the ball valve is in the open position. An annular flow space is defined by the chamber wall and the annular wall, and the annular flow space is positioned around the ball retaining chamber. The annular flow space receives petroleum fluid from the lower cage channel and transmits petroleum fluid to the upper cage channel. The upper cage may also define a ball hole providing fluid communication between the upper cage channel and the ball retaining chamber.
