11. The beverage dispenser according to claim 2 , wherein the valve is configured to decrease the pressure of the base fluid dispensed therefrom to match the pressure of the pressurized ambient air dispensed from the gas system.

12. The beverage dispenser according to claim 11 , wherein the valve has:

an inlet end configured to receive the base fluid, wherein the inlet end has an inlet hole;

a channel through which the base fluid is conveyed;

a diaphragm in the channel biased toward the inlet end; and

an outlet end configured to dispense the base fluid;

wherein when the inlet end receives the base fluid having a pressure less than a threshold pressure the diaphragm covers the inlet hole and thereby prevents the base fluid from conveying through the valve; and

wherein when the inlet end receives the base fluid having a greater than or equal to the threshold pressure the diaphragm is moved away from the inlet hole by the base fluid such that the diaphragm is spaced apart from the inlet hole and the base fluid dispenses from the outlet end.

13. The beverage dispenser according to claim 12 , wherein the valve has a spring in the channel that applies a spring force on the diaphragm to thereby bias the diaphragm toward the inlet end, and wherein the spring is adjustable to change the spring force applied on the diaphragm and thereby change the threshold pressure.

14. The beverage dispenser according to claim 13 , wherein increasing the spring force applied on the diaphragm increases the threshold pressure.

15. A beverage dispenser comprising:

a gas system configured to collect ambient air, pressurize the ambient air, and dispense pressurized ambient air, the gas system has:

a compressor configured to pressurize the ambient air;

a gas storage device configured to store the pressurized ambient air before the pressurized ambient air is dispensed from the gas system to thereby reduce duty cycle of the compressor; and

a gas regulator downstream from the gas storage device and configured to decrease pressure of the pressurized ambient air before the pressurized ambient air is dispensed from the gas system;

a valve configured to dispense a base fluid;

a concentrate system configured to dispense a concentrate;

a manifold configured to mix the based fluid and the concentrate to form a mixed beverage and further inject the pressurized ambient air into the mixed beverage to thereby form a gas-injected mixed beverage, wherein the manifold has an injector through which the pressurized ambient air injects into the mixed beverage; and

a nozzle configured to apply a back-pressure upstream on the gas-injected mixed beverage and dispense the gas-injected mixed beverage.

16. The beverage dispenser according to claim 15 , wherein the valve has:

an inlet end configured to receive the base fluid, wherein the inlet end has an inlet hole;

a channel through which the base fluid conveys;

a diaphragm in the channel biased toward the inlet end; and

an outlet end configured to dispense the base fluid;

wherein when the pressure of the base fluid received by the inlet end is less than a threshold pressure the diaphragm covers the inlet hole and thereby prevents the base fluid from conveying through the valve; and

wherein when the pressure of the base fluid received by the inlet end is greater than or equal to the threshold pressure the diaphragm is moved away from the inlet hole by the base fluid such that the diaphragm is spaced apart from the inlet hole and the base fluid dispenses from the outlet end.

17. The beverage dispenser according to claim 16 , wherein the valve has a spring in the channel that applies a spring force on the diaphragm to thereby bias the diaphragm toward the inlet end, and wherein the spring is adjustable to change the spring force applied on the diaphragm and thereby change the threshold pressure.
