Valve for hydraulic control and balancing of fluid flow rate

A multiway hydraulic valve or diverter valve comprising:

• a valve body and a plurality of connecting openings;
• and
• at least one fluid flow rate control valve comprising:
• a tubular body having an inlet opening, an outlet opening, and an actuating opening that is extending along only a portion of a circumference of the tubular body;
• and
• a rotating hollow shutter rotatively housed inside said tubular body and having a rotation axis, said rotating hollow shutter being crossable by a fluid and configured such that a passage cross-section inside the valve is changeable;
• wherein the rotating hollow shutter comprises at least one first eccentric opening rotatively cooperating with at least one mating second eccentric opening formed on an inner wall of said tubular body;
• wherein said actuating opening exposes a portion of the rotating hollow shutter and allows access to the portion of the rotating hollow shutter for actuation of the rotating hollow shutter;
• and
• wherein said rotating hollow shutter is configured so that a rotation of said at least one first eccentric opening with respect to said at least one mating second eccentric opening corresponds to a variation of the passage cross-section in a direction coinciding with the rotation axis of the rotating hollow shutter.
