1. An intercepting valve for a fluid, comprising: a valve body having a fluid input duct and fluid output duct, suitable for joining to a distribution network of the fluid;an obturator lodged at least partially in the valve body between the input duct and output duct, the obturator being rotatable f
1. An intercepting valve for a fluid, comprising: a valve body having a fluid input duct and fluid output duct, suitable for joining to a distribution network of the fluid;an obturator lodged at least partially in the valve body between the input duct and output duct, the obturator being rotatable from a closed position, in which it prevents the transit of the fluid from the input duct to the output duct, to a first open limit position, in which it defines a first opening for the transit of the fluid, the first opening having a first contour for a first characterisation of the fluid;wherein in a further open limit position, the obturator defines a further opening, the opening having a further contour, different from the first, for a further characterisation of the fluid;wherein the obturator passes from the closed position to the first open limit position by turning clockwise and passes from the closed position to the further open limit position by turning anti-clockwise; andwherein the obturator, in the first open limit position strikes against the wall, to prevent further rotation clockwise and, in the further open limit position strikes against the wall to prevent any further rotation anti-clockwise. 2. Valve according to claim 1, wherein the obturator defines the openings jointly with the walls of the valve body. 3. Valve according to claim 1, comprising an obturator bay between the input duct and the output duct, and wherein the obturator comprises a main body, lodged in the obturator bay, comprising a sealing wall which, in the closed position, interrupts the fluidic connection between the input duct and the output duct, the sealing wall having a facing surface, facing the input duct in the closed position. 4. Valve according to claim 3, comprising at least one sealing strip positioned on the facing surface so as to form a seal with the entrance of the input duct. 5. Valve according to claim 4, wherein the strip extends along the facing surface, covering it beyond the cross-section of the entrance of the input duct. 6. Valve according to claim 3, wherein the facing surface is a portion of a cylindrical surface with circular cross-section. 7. Valve according to claim 3, wherein the valve body has an access bay, communicating with the obturator bay, which surmounts the input and output ducts, the obturator being inserted inside the valve body through the access bay. 8. Valve according to claim 1, wherein the input duct and the output duct have a rectilinear delivery axis wherein the obturator can be rotated around a rotation axis, the rotation axis being perpendicular to the delivery axis.
