Abstract
A control valve for a fluid flow includes: a valve body that defines an inlet and an outlet for the fluid, an obstructer inserted in the valve body, and an actuator system configured for reversibly translating the obstructer between a first position, in which the obstructer allows the passage of the fluid between the inlet and the outlet, and a second position, in which the obstructer prevents the passage of the fluid between the inlet and the outlet; the control valve further includes a turbine rotor housed inside the valve body, wherein the rotor includes a plurality of blades and is configured for continuously rotating under the action of the fluid flowing between the inlet and the outlet, the rotor rotating about an axis of rotation substantially aligned with the direction of translation of the obstructer.
