ABSTRACT A beverage dispensing system includes a non-refrigerated pressurized source of carbonated beverage connected through a refrigeration line to a four-way valve which directs the beverage to one side or the other of a metering device to fill it, while being also connected to said other or said one side respect- ively to drain the other side of the metering device and to direct the beverage through a restrictor to a dispensing valve. The structure is miniaturized and thus there are relatively high velocity flows of beverage which would tend to cause foaming. Foaming is eliminated by the restrictor which maintains the pressure at the four-way valve and upstream therefrom at a pressure level which is in excess of the partial pressure of the carbondioxide gas in the beverage, thus eliminating foaming.
