7. The combined water and syrup valve assembly of claim 1 wherein the water inlet and the water outlet are positioned such that the outlet is at an angle of approximately 90\xb0 compared to the inlet.
8. A beverage dispenser comprising the combined water and syrup valve assembly of claim 1.
9. A carbonated water valve for use in a beverage dispenser comprising:
a) a housing having an inlet and an outlet and a carbonated water flow path there between;

c) a spring acting against the diaphragm to urge it against the sealing ring in opposition to force generated by pressure of carbonated water in the inlet;
d) an inlet channel upstream of the sealing ring; and
e) a throttling pin positioned in said inlet channel and responsive to movement of the diaphragm to partially block the inlet channel when the pressure in the inlet forces the diaphragm to open against the spring force, the movement of the diaphragm thus regulating the flow of water through the housing;
f) the flow path through the valve being configured to minimize the breakout of carbonation from the carbonated water.
10. The carbonated water valve of claim 9 wherein the flow path has channels and the channels are made with rounded corners as a way of minimizing carbonation breakout.
11. The carbonated water valve of claim 10 wherein the flow path includes four flow channels for directing flow around the diaphragm.
12. The carbonated water valve of claim 9 wherein the internal volume of the valve is balanced with the flow rate through the valve and back pressure so that the volume of the flow path is minimized as a way of minimizing carbonation breakout.
13. The carbonated water valve of claim 9 wherein the flow path has an outlet adjacent the sealing ring as a way of minimizing carbonation breakout.
14. The carbonated water valve of claim 13 wherein the sealing ring lies in a plane, and both the inlet and outlet are located on the same side of said plane.
15. A beverage dispenser comprising the carbonated water valve of claim 9.
16. A water valve for use in a beverage dispenser comprising:
