1. A filling valve for filling a container comprising: a valve body having a chamber;a nozzle assembly connected to the chamber, the nozzle assembly comprising a nozzle comprising an outlet,a ball cage, anda peripheral surface about a central axis, the peripheral surface comprising a channel seat extending outwardly from the peripheral surface;an expandable sealing member operably positioned around the peripheral surface without interruption, and positioned above the outlet, the expandable sealing member comprising an expanding portion, a container sealing surface for sealably engaging the container when the expanding portion is expanded by a pressurizing gas, a valve sealing portion for sealably engaging the peripheral surface when the expanding portion is expanded by the pressurizing gas, and a lip that extends upwardly from the valve sealing portion, the lip mating against the channel seat when the expanding portion is expanded by the pressurizing gas;a vent tube positioned vertically above and in communication with the ball cage; anda fluid passageway operatively positioned for communicating pressurizing gas from the vent tube to the container and then to a seal cavity for expanding the expanding portion of the sealing member. 2. The filling valve of claim 1, the nozzle assembly further comprising a valve seat having at least one aperture connecting the valve body chamber with the nozzle and a substantially planar sealing surface around the at least one aperture, and the filling valve further comprising a closure valve selectively engaging the sealing surface, adapted for controlling a flow of fluid through the at least one aperture. 3. The filling valve of claim 2, further comprising: a valve stem being adapted for operatively moving the closure valve between a valve open position and a valve closed position, the valve stem comprising at least one outwardly extending protrusion for guiding the valve stem within the valve body chamber. 4. The filling valve of claim 1, wherein an inner diameter of valve sealing portion sealably engages an outer diameter of the peripheral surface when the expanding portion is expanded by the pressurizing gas. 5. The filling valve of claim 1, further comprising a snift valve in communication with the seal cavity and the fluid passageway, the snift valve causing a release of pressurizing gas from the seal cavity, thereby causing the expanding portion of the expandable sealing member to deflate and disengage the container from the valve. 6. The filling valve of claim 1, wherein the channel seat is a flange extends from the peripheral surface, and the lip mates against the flange. 7. The filling valve of claim 5, wherein the lip angles inwardly from the valve sealing portion, and, when mated to the channel seat, further acts to prevent egress of a liquid dispensed into the container when the snift valve is engaged. 8. The filling valve of claim 1, where the nozzle is removable from the valve body. 9. The filling valve of claim 8, where the nozzle is removable to allow different nozzles for different sized containers to be positioned on the valve body. 10. The filling valve of claim 1, the outlet comprising: a plurality of ports oriented in a downwardly direction. 11. The filling valve of claim 1, the outlet comprising: a plurality of ports oriented in a downwardly direction defined by an outward angle and a tilt angle, the ports being positioned below the peripheral surface and each having an inlet in communication with the valve body chamber. 12. The filling valve of claim 1, wherein the lip engages the channel seat when gas in introduced into the seal cavity and disengages from the channel seat upon a release of pressurizing gas from the seal cavity, thereby assisting in preventing egress of a liquid introduced into the container above the expandable sealing member. 13. The filling valve of claim 1, further comprising: a valve stem being adapted for operatively moving between a valve open position and a valve closed position, a cap being vertically positioned above the valve stem and vent tube and selectively contacting the valve stem, and a valve cam being positioned above the cap, the valve cam being adapted for pushing the cap and valve stem axially downward into the valve closed position. 14. The filling valve of claim 13, further comprising: a vent seal capable of closing the vent tube positioned beneath the cap, a spring positioned between the cap and the vent seal, the spring being adapted for pressing the vent seal against the vent tube for closing the vent tube when the cap and valve stem are in the valve closed position. 15. The filling valve of claim 1, the nozzle assembly further comprising a snift valve being adapted for releasing pressurizing gas from said container when the snift valve is open, and where the fluid passageway is in communication with the snift valve and operatively positioned for communicating pressurizing gas from the vent tube for expanding the sealing member when the snift valve is closed. 16. The filling valve of claim 1, further comprising a snift valve, a first valve body passageway and a second valve body passageway, each formed in the valve body; the first valve body passageway connecting the seal cavity to the snift valve; the first valve body passageway comprising an aperture through a wall of the valve body. 17. The filling valve of claim 16 further comprising a bell, the bell having a bell passageway connecting a bell inner area to a fluid cavity formed between a lower surface of the valve body and an upper surface of the bell, wherein, when the snift valve is engaged, a cleaning fluid flows through the nozzle and into the bell inner area, then through the bell passageway into the fluid cavity, then into the second valve body passageway, then through a cleaning fluid conduit to an outlet. 18. The filling valve of claim 17 wherein the outlet is routed through the bell and into the second housing passageway and, when a snift actuator causes the snift valve to engage, the cleaning fluid passes around the inside of the seal. 19. The filling valve of claim 1, further comprising a snift valve and a bell, the bell having a first port in an upper interior portion of the bell, the first port connected to a channel formed by the bell and the valve body, and a second port in a back of the valve body, the second port connected to a hose fitting. 20. An expandable sealing member for a filling valve for filling a container, the filling valve having a nozzle assembly having a nozzle outlet and a peripheral surface about a central axis, the peripheral surface comprising a channel seat extending outwardly from the peripheral surface, a snift valve, and a vent tube positioned vertically above the nozzle assembly, the sealing member comprising: a valve sealing portion adapted to be operably positioned around the peripheral surface of the nozzle assembly when installed,a container sealing surface adapted to be operably positioned on an inside of the container when installed,a lip that extends upwardly from the valve sealing portion, andan expanding portion adapted to be operably positioned above the nozzle outlet when installed the expanding portion capable of being expanded by a pressurizing gas introduced from the vent tube into a space above the sealing member when installed, the expanding portion, when installed and expanded, causing a) the valve sealing portion to sealably engage the peripheral surface without interruption, b) the container sealing surface to sealably engage the container when the container is presented to the filling valve, and c) the lip to sealably engage the channel seat, thereby assisting in preventing egress of a liquid introduced into the container above the sealing member when installed, and the snift valve causing a release of pressurizing gas from the space above the sealing member when installed, thereby causing the expanding portion to deflate, and the valve sealing portion, the container sealing surface and the lip to disengage their respective surfaces.
