What is claimed is: 1. A valve, comprising: a body portion defining a conduit; and a control element coupled to the body portion and configured to selectively engage the body portion adjacent the conduit, the control element configured to be axially repositioned based on axial movement of the body portion, the body portion being movable between a first configuration in which the control element is sealingly coupled to the body portion and a second configuration in which the entire control element is disposed a spaced distance from the body portion. 2. The valve of claim 1, further comprising: a cap configured to be coupled to the body portion. 3. The valve of claim 1, further comprising a retention element coupled to the body portion substantially within the conduit, the control element being coupled to the retention element. 4. The valve of claim 1, wherein the control element includes a substantially flexible membrane. 5. The valve of claim 4, wherein the control element is at least one of rubber or plastic. 6. The valve of claim 3, wherein the retention element includes at least one rib disposed within the conduit, and a post coupled to the at least one rib, the post extending substantially along an axis of the conduit. 7. The valve of claim 1, wherein the body portion is an unitary construction. 8. The valve of claim 1, wherein the body portion includes a base member, the conduit being defined by a chamber, in the first configuration, the chamber is disposed substantially above the base member, and in the second configuration, the chamber is disposed substantially below the base member. 9. The valve of claim 1, wherein the body portion includes a base member, the conduit being defined by a chamber having a first end and a second end, the first end is disposed substantially above the base member in the first configuration, and the first end is disposed substantially coplanar with the base member in the second configuration. 10. The valve of claim 1, wherein the body portion includes a base member, the conduit being defined by a chamber having a first end and a second end, the first end is disposed substantially above the base member in the first configuration, and the first end is disposed substantially below the base member in the second configuration. 11. A valve, comprising: a body portion reconfigurable between a first configuration and a second configuration, the body portion having a base member, a first chamber having a first diameter, a second chamber coupled between the first chamber and the base member and defining an opening having a second diameter greater than the first diameter; and a control element coupled to the body portion, the control element being axially movable with respect to the first chamber and being disposed a fixed distance from the first chamber when the body portion is in the first configuration and when the body portion is in the second configuration. 12. The valve of claim 11, wherein in the first configuration, the first chamber is disposed above, and coaxially with, the second chamber, and in the second configuration, the first chamber is disposed substantially within, and substantially concentric with, the second chamber. 13. The valve of claim 11, further comprising: a cap configured to be coupled to the body portion. 14. The valve of claim 11, further comprising a retention element coupled to the body portion substantially within the conduit, the control element being coupled to the retention element. 15. The valve of claim 11, wherein the control element includes a substantially flexible membrane. 16. The valve of claim 15, wherein the control element is at least one of rubber or plastic. 17. The valve of claim 14, wherein the retention element includes at least one rib disposed within the conduit, and a post coupled to the at least one rib, the post extending substantially along an axis of the conduit. 18. The valve of claim 11, wherein in the first configuration, the first chamber is disposed substantially above the base member and in the second configuration the first chamber is disposed substantially below the base member. 19. The valve of claim 11, wherein in the first configuration, the first chamber and the second chamber are disposed substantially above the base member and in the second configuration the first chamber and the second chamber are disposed substantially below the base member. 20. A valve, comprising: a body portion reconfigurable between a first configuration and a second configuration, the body portion having, a base member, a first chamber having a diameter, and a second chamber coupled between the first chamber and the base member when the body portion is in the first configuration, the second chamber defining an opening having a diameter greater than the diameter of the first chamber, the second chamber having a first end coextensive with at least a portion of the first chamber and a second end coextensive with at least a portion of the base member; and a control element coupled to the body portion, the control element being sealingly coupled to the second end of the second chamber when the body portion is in the first configuration.
