A dispense tape (10) to control the flow of carbonated beers is configured to minimize pressure drop and turbulence in beer flow to an outlet nozzle (14) when open, the tap having flow restrictor means (52) operatively connected as a downstream extension of the tap valve (30), located in the path of beer flowing from the valve, arranged only to affect beer flow when the tap is nearly closed and configured to substantially restrict beer flow to maximize pressure drop and turbulence; choice of nozzle length/bore ratio enabling either a creamy flow or a squib of beer to be dispensed.

A tap, for a carbon dioxide gas pressure dispense system for beer, comprising: a tap body; a nozzle, forming part of said tap body, to convey dispensed beer to a receptacle therefor; a counterbore in said tap body and communicating with said nozzle; a valve seat within said tap body and about said counterbore; a reciprocating valve housed in said tap body to control flow of beer through said tap; said reciprocating valve having a valve member movable by a valve operating mechanism towards and away from said valve seat to close and open said tap; said reciprocating valve being configured to minimize pressure drop and turbulence in the flow of beer through said tap when said valve member is in the open position; said valve member having an extension that projects through said valve seat into said counterbore; said extension having a radially outwardly directed flange that is always disposed within said counterbore defining a range of movement of said valve member proximate the closed position thereof; said flange cooperating with said counterbore to define a narrow annulus to substantially restrict beer flow and create a turbulence-inducing pressure drop so as to facilitate an automatic positioning of the valve operating mechanism by an operator to a turbulence and pressure drop-inducing position within said range and hence a generally automatic production of foam in the tap prior to said flange leaving said counterbore in an opening direction or after said flange enters the counterbore in a closing direction and without requiring manuel adjustment of the parts of the reciprocating valve and the operating mechanism relative to each other.
