Abstract: Various embodiments include a control valve comprising a first valve assembly between an inlet and an outlet. The first valve assembly comprises: a valve seat fixed relative to the valve body with an opening in a sidewall; a slider rotating inside the valve seat to block the opening, but stationary in an axial direction; a regulating valve plug with an opening at one end, surrounding the valve seat and movable in the axial direction to block the opening in the sidewall of the valve seat; and a first valve stem connected to the slider and to the regulating valve plug, the first valve stem having one end extending out of the valve body. A first overlap between the slider and the opening and a second overlap of the plug and the opening are changed by movement of the first valve stem.
