A premix dispensing valve assembly for a beverage dispenser includes a housing which includes an inlet to deliver premix fluid, a compensator within the housing for subjecting a controlled pressure drop on the premix fluid which includes an outlet communicating exterior to the housing, and a regulator within the housing for applying a variable dampening effect against high fluid pressures that accompany the premix fluid upon entry into the premix dispensing valve assembly. The regulator is cooperatively linked to the inlet of the housing and communicates with the compensator. As such, integrating the regulator with the compensator optimally allows for premix fluid to maintain a constant pressure and, thus, prevent complications arising from loss of carbonation. The premix dispensing valve assembly further includes a premix delivery channel within the housing for communicating premix fluid from the inlet of the housing to the regulator. The premix dispensing valve assembly may further include a black block assembly positioned within the housing and in communication with the inlet to eliminate the need to depressurize the entire premix beverage dispenser when disassembly of a particular premix dispensing valve assembly is required.
