1. A control valve (1) comprising:

  • a valve body (2) which has an inlet opening (3) and an outlet opening (4) for a fluid;

    recovery means (5) configured to transfer the kinetic and/or potential energy extracted from said fluid out of said valve body (2);

    a obturator (6) placed within said valve body (2) between said inlet and outlet openings (3, 4), said obturator (6) being configured to direct the fluid towards the recovery means (5) and to assume a closing configuration of the valve (1);

    wherein said recovery means (5) comprise a rotating element (7) placed within said valve body (2) downstream of the obturator (6) and configured to be put into rotation by said fluid;

    the inlet opening (3) defining a first fluid flow direction, the outlet opening (4) defining a second fluid flow direction, the first fluid flow direction being (a) in the same direction as, and (b) parallel to, the second fluid flow direction;

    wherein said obturator (6) comprises at least a first plate (10) and a second plate (11) placed transversally with respect to the axis of rotation (A) of the rotating element (7);

    said first plate (10) and second plate (11) each having at least one passage opening (12);

    said first plate (10) and said second plate (11) being mobile with respect to each other to pass reversibly from a closing configuration wherein said passage openings (12) are completely disaligned with respect to each other to prevent the passage of the fluid to at least an opening configuration wherein said passage openings (12) are at least partially overlapping to permit the passage of the fluid, each of said first and second plates (10, 11) having a central portion, the first plate central portion being unconstrained with respect to the second plate central portion.
