1. A valve comprising: a cup-shaped element having an outer surface on which a driver element is mountable and a flange having a surface for connecting the valve to a dispensing unit and a re-entrant portion defining a housing for a seal gasket, the re-entrant portion having a substantially circular configuration with a radial protuberance, the protuberance being superposed on a dispensing hole for the fluid when the valve is mounted on the dispensing unit;a core inserted in the cup-shaped element, the core comprising at least one seal element arranged to block a first fluid passage provided in a bush, the core being movable within the cup-shaped element against the action of an elastic element between a first position in which the seal element rests on the bush to close the first fluid passage and a second position in which the seal element is detached from the bush to open the first fluid passage, the bush being associated with a closure element for the cup-shaped element,the closure element cooperating with an inner surface of said cup-shaped element to fix the closure element to the cup-shaped element,wherein the core, the bush and the closure element are disposed on the same side of the surface of the flange for connecting the valve to the dispensing unit. 2. The valve of claim 1, wherein the cup-shaped element, the flange, and the re-entrant portion are formed in one piece. 3. The valve of claim 1, wherein the closure element comprises at least one second passage for fluid, through which the fluid can flow when the core is in its second position. 4. The valve of claim 1, wherein the flange is of square shape, passage holes being provided at the corners of the square for screws for fixing the valve to the dispensing unit. 5. The valve of claim 1, wherein the cup-shaped element comprises a first step on which the elastic element rests and a second step on which side wall of the closure element rests. 6. The valve of claim 1, wherein the driver element is an electromagnet. 7. The valve of claim 1, further comprising a seal gasket in said housing defined by the re-entrant portion. 8. The valve of claim 1, further comprising a fixed core coupled to the cup-shaped element distant from the flange, the fixed core having a passage therethrough that is in fluid communication with an interior of the cup-shaped element via an opening, wherein the opening is closed by the core when the core is in the second position. 9. The valve of claim 1, wherein the closure element comprises an outer cylindrical part that cooperates with the cup-shaped element. 10. The valve of claim 9, wherein the outer cylindrical part of the closure element is fixed into the cup-shaped element by friction. 11. The valve of claim 1, wherein the closure element comprises a bayonet coupling. 12. The valve of claim 11, wherein the cup-shaped element includes a boss cooperating with an L-shaped groove provided in the wall of the closure element. 13. The valve of claim 1, wherein the closure element comprises a housing seat for the bush. 14. The valve of claim 13, wherein the bush comprises a protuberance defining a first annular housing for an O-ring. 15. The valve of claim 14, wherein the first annular housing is perimeterally bounded by a further part of the bush. 16. The valve of claim 14, wherein the first annular housing is perimeterally bounded by a portion of the seat. 17. A valve comprising: a cup-shaped element having an outer surface on which an electromagnet driver is mountable and a flange having a surface for directly connecting the valve to a dispensing unit;a core inserted into the cup-shaped element, the core comprising at least one seal element arranged to block a first fluid passage provided in a bush, the core being movable within the cup-shaped element against the action of an elastic element between a first position in which the seal element rests on the bush to close the first fluid passage and a second position in which the seal element is detached from the bush to open the first fluid passage, the bush being associated with a closure element for the cup-shaped element, the closure element including means cooperating with an inner surface of said cup-shaped element to fix the closure element to the cup-shaped element,the closure element comprises at least one second passage for fluid, through which the fluid can flow when the core is in the second position,the core, the bush and the closure element are disposed on the same side of the surface of the flange for connecting the valve to the dispensing unit,wherein the flange includes a re-entrant portion defining a second housing for a seal gasket, the re-entrant portion having a substantially circular configuration with a radial protuberance, the protuberance being superposed on a dispensing hole for the fluid when the valve is mounted on the dispensing unit. 18. The valve of claim 17, wherein the bush comprises a protuberance defining a first annular housing for an O-ring. 19. The valve of claim 17, further comprising a seal gasket in said housing defined by the re-entrant portion. 20. The valve of claim 17, further comprising a fixed core coupled to the cup-shaped element distant from the flange, the fixed core having a passage therethrough that is in fluid communication with an interior of the cup-shaped element via an opening, wherein the opening is closed by the core when the core is in the second position.
