A valve for fluids, comprising: - an inlet opening of a fluid extending along a respective axis of extension; - an outlet opening of the fluid extending along a respective axis of extension positioned transversally to the axis of extension of the inlet opening; - a shutter operatively associated with the inlet opening and movable between an open position and a closed position of the inlet opening along the axis of extension of the latter; - a unit for moving the shutter along the axis of extension of the inlet opening and operatively associated with the shutter for moving it; the movement unit comprising a rod extending between a respective operating portion which can engage the shutter for moving it and a respective drive portion opposite to the operating portion; - the shutter defines a gap placed in fluid communication with the inlet opening and extending through the shutter towards a transient space which is closed, at least during the closed position of the shutter, with respect to the outlet opening; the transient space extending along the axis of extension from a bottom wall of the valve to a contact surface inside the shutter in such a way that the fluid penetrates from the inlet opening towards the transient space through the gap and acts on the shutter in the opposite direction to the fluid acting directly on the shutter from the inlet opening; - characterised in that it comprises means for driving the rod associated with the drive portion of the rod; the drive means comprising an electromagnetic element to move the rod along a first direction or along a second direction; and in that the drive means of the rod comprise a voice-coil type system. - an inlet opening of a fluid extending along a respective axis of extension; - an outlet opening of the fluid extending along a respective axis of extension positioned transversally to the axis of extension of the inlet opening; - a shutter operatively associated with the inlet opening and movable between an open position and a closed position of the inlet opening along the axis of extension of the latter; - a unit for moving the shutter along the axis of extension of the inlet opening and operatively associated with the shutter for moving it; the movement unit comprising a rod extending between a respective operating portion which can engage the shutter for moving it and a respective drive portion opposite to the operating portion; - the shutter defines a gap placed in fluid communication with the inlet opening and extending through the shutter towards a transient space which is closed, at least during the closed position of the shutter, with respect to the outlet opening; the transient space extending along the axis of extension from a bottom wall of the valve to a contact surface inside the shutter in such a way that the fluid penetrates from the inlet opening towards the transient space through the gap and acts on the shutter in the opposite direction to the fluid acting directly on the shutter from the inlet opening; - characterised in that it comprises means for driving the rod associated with the drive portion of the rod; the drive means comprising an electromagnetic element to move the rod along a first direction or along a second direction; and in that the drive means of the rod comprise a voice-coil type system.
