A system comprising, a pressurized container including hollow portion and outer portion, pressurized container maintains pressure level in the hollow portion, transport system including two conduits, one transport being coupled to an interface and a valve port, the interface coupled to the hollow portion, the interface maintains pressure level in the hollow portion, one valve port allows flow of liquid volume through one conduit to a dispensing interface via another valve port, an external container is airtight and operable to dispense another liquid volume stored within, another conduit is coupled to the external container and further valve port to refill the liquid volume via the valve, pressure regulation system connected to pressurized container, pressure regulation system including a pressure conduit extending from outer portion through a pressure interface, pressure regulation system operable to compress liquid volume in the environment and a control system controls the valve and pressure regulation system.

A mounting assembly includes a beverage mounting assembly having a housing. The housing has a housing wall that surrounds a cavity. A valve body is connectable to the beverage mounting assembly. The valve body is connectable to the beverage mounting assembly via a clip. The clip is insertable into both the housing and the valve body to connect the valve body to the beverage mounting assembly. At least one actuator is disposed in the cavity of the housing. The actuator rotates from a closed position to an open position that actuates pressure to the valve body from a liquid source. The actuator is separate from the clip that connects the housing to the valve body.
