A device and method are provided for dispensing a beverage from a pressurized container. The dispensing device includes an integral source of compressed gas for maintaining the beverage within the container at a desired pressurized state. The dispensing device also includes a regulator for controlling the flow of gas from the compressed gas source to the interior of the container, as well as a pressure relief mechanism that accounts for potential over pressurization of the container. The beverage is selectively dispensed by actuation of a tap handle. Delivery is achieved through the device by a resilient delivery tube, and the delivery tube is either pinched closed or allowed to decompress by the actuation of the tap handle. In another embodiment, a check valve is used to control flow of the beverage in which the tap handle activates a transfer rod to seat and unseat a check element. The device can be manufactured in either a unitary construction or a modular construction. Modular construction provides greater flexibility in testing and replacement of defective components.
