A ball valve is provided for precise throttling of fluid through the valve. The valve includes a valve housing having a fluid passageway and a valve seat intermediate the fluid passageway. A valve stem extends through the valve housing into the valve seat and is rigidly connected to a spherical valving member rotatably mounted in the valve seat. The valving member includes a passageway extending therethrough. The passageway is cylindrical from the upstream end substantially to the downstream end. However, the downstream end is partly closed by a spherically generated throttling wall. A generally oblong outlet extends through the throttling wall. The long axis of the oblong outlet is generally orthogonally aligned to the axis of the passageway and to the rotational axis of the valve stem.
