The apparatus of claim 3, wherein the outlet port includes a lip at the base of the outlet port and the ends or periphery of the cross member are engaged with the lip when the valve is in the first, closed position, and wherein the ends or periphery of the cross member are disengaged with the lip when the valve is in the second, open position. 6. The apparatus of claim 1, further including: a second outlet port that provides a passageway from the inside of the balloon envelope to the atmosphere;a second bracket extending from the bottom of the plate;a second linear actuator having a first end and a second end, the first end of the second linear actuator attached to the second bracket;wherein a second valve having a periphery is positioned over the second outlet port;wherein the second end of the second linear actuator is attached to the second valve;wherein the second valve is movable from a first, closed position where a seal is provided by the engagement of the periphery of the second valve and a periphery of the second outlet port to a second, open position where the periphery of the second valve is disengaged from the periphery of the second outlet port and moved within the interior of the balloon envelope by movement of the second end of the second linear actuator to open the passageway between the inside of the balloon envelope and the atmosphere to allow gas or air to be vented from the balloon envelope. 7. The apparatus of claim 1, wherein the valve is an umbrella valve. 8. The apparatus of claim 1, wherein a first series of brackets are positioned on a bottom side of the plate and a second series of brackets are positioned on an exterior of a fill housing, and a line is threaded through the apertures in the first series of brackets and apertures in the second series of brackets and tightened to secure the fill housing to the plate. 9. The apparatus of claim 6, wherein the outlet ports have a diameter of 25 millimeters. 10. The apparatus of claim 1, wherein the periphery of the valve is round. 11. The apparatus of claim 1, wherein the periphery of the outlet port is recessed beneath a surface of the plate and polished to provide a seal formed by the engagement of the periphery of the valve with the periphery of the outlet port. 12. A balloon comprising: a balloon envelope;a bladder positioned within the balloon envelope;a plate secured to the balloon envelope, the plate having an outlet port;wherein the outlet port provides a passageway from an inside of the balloon envelope to the atmosphere;a first bracket extending from the bottom of the plate;a first linear actuator having a first end and a second end, the first end of the linear actuator attached to the first bracket;a valve having a periphery is positioned over the outlet port;the second end of the linear actuator is attached to the valve;a control system that is configured, upon receiving a signal to decrease the amount of air within the bladder within the balloon envelope, to cause the first linear actuator to move to cause the valve to move from a first, closed position where a seal is provided by the engagement of the periphery of the valve and a periphery of the outlet port to a second, open position where the periphery of the valve is disengaged from the periphery of the outlet port and moved within an interior of the balloon envelope by movement of the second end of the linear actuator to open the passageway between the inside of the bladder within the balloon envelope and the atmosphere to allow air to be vented from the bladder within the balloon envelope. 13. The balloon of claim 12, further including: a second outlet port that provides a passageway from the inside of the bladder within the balloon envelope to the atmosphere;a second bracket extending from the bottom of the plate;a second linear actuator having a first end and a second end, the first end of the second linear actuator attached to the second bracket;wherein a second valve having a periphery is positioned over the second outlet port;wherein the second end of the second linear actuator is attached to the second valve;wherein the second valve is movable from a first, closed position where a seal is provided by the engagement of the periphery of the second valve and a periphery of the second outlet port to a second, open position where the periphery of the second valve is disengaged from the periphery of the second outlet port and moved within the interior of the balloon envelope by movement of the second end of the second linear actuator to open the passageway between the bladder within the balloon envelope and the atmosphere to allow air to be vented from the bladder within the balloon envelope to the atmosphere. 14. The balloon of claim 12, wherein the valve is an umbrella valve. 15.
