A method and apparatus for controlling a flow of a fluid through a valve. In one illustrative embodiment, an apparatus comprises an elongate member, an actuation device, and a valve body. The actuation device is configured to move the elongate member, which may be associated with the actuation device, between an open position and a closed position. The valve body is configured for attachment to the actuation device such that the elongate member is positioned within the valve body. Fluid that flows into the valve body from a fluid source is allowed to flow out of the valve body when the elongate member is in the open position.

The apparatus of claim 3, wherein the second element is a second protrusion extending from the valve body comprising the second channel through which the fluid flows. 6. The apparatus of claim 3, wherein at least a portion of the second element forms a nozzle through which the fluid is dispensed onto a surface. 7. The apparatus of claim 1, wherein moving the elongate member in the direction towards the actuation device creates a negative pressure within the second element that prevents the fluid from flowing out of the second channel. 8. The apparatus of claim 3, wherein the first element comprises a first channel and the second element comprises the second channel and wherein the fluid is allowed to flow into the second channel from the first channel when the elongate member is in the open position and prevented from flowing into the second channel from the first channel when the elongate member is in the closed position. 9. The apparatus of claim 1, wherein the fluid comprises a viscosity within a selected range. 10. The apparatus of claim 9, wherein the fluid comprising the viscosity within the selected range is a sealant. 11. The apparatus of claim 1 further comprising: the fluid source. 12. The apparatus of claim 1 further comprising: a nozzle associated with the valve body in which the fluid is dispensed through the nozzle onto a surface. 13. The apparatus of claim 12 further comprising: a number of fluid transfer elements configured to connect the nozzle to the valve body. 14. A fluid dispensing system comprising: a fluid source holding fluid comprising a viscosity within a selected range;an elongate member, positioned within a valve body, comprising a plug portion at one end of the elongate member;an actuation device that moves the elongate member, which is associated with the actuation device, linearly in a direction along an axis away from the actuation device to an open position and toward the actuation device to a closed position;a disposable valve body that attaches to the actuation device such that the elongate member is positioned within the disposable valve body;a first element associated with the disposable valve body attached to the fluid source; anda second element associated with the disposable valve body in which the fluid flows from the fluid source into the disposable valve body through the first element and out of the disposable valve body through the second element when the elongate member is in the open position and in which removing the disposable valve body allows access to the elongate member such that the elongate member can be cleaned; the disposable valve body comprising: a hollow portion; a connecting channel connected to the hollow portion and comprising a first diameter, the first diameter being constant; a second channel, connected at one end to the connecting channel and open at a second end, and comprising a diameter that expands from the first diameter to a second diameter, the second diameter being constant, and narrows from the second diameter to a third diameter, the third diameter being constant, such that the plug portion forms an interference fit with the connecting channel when the elongate member is in the closed position, the connecting channel being narrower than both the hollow portion and the second channel. 15. A method for controlling a flow of fluid through a valve, the method comprising: receiving the fluid from a fluid source within a valve body of the valve; andmoving an elongate member, comprising a plug portion and positioned within the valve body, away from an actuator device to an open position and toward the actuator device to a closed position, the actuation device associated with the elongate member such that the actuation device, via the elongate member, controls the flow of the fluid out of the valve body; attaching the valve body to the actuation device such that the elongate member associated with the actuation device is positioned within the valve body, the valve body comprising: a hollow portion; a connecting channel connected to the hollow portion and comprising a first diameter, the first diameter being constant; a second channel, connected at one end to the connecting channel and open at a second end, and comprising a diameter that expands from the first diameter to a second diameter, the second diameter being constant, and narrows from the second diameter to a third diameter, the third diameter being constant, such that the plug portion forms an interference fit with the connecting channel when the elongate member is in the closed position, the connecting channel being narrower than both the hollow portion and the second channel. 16.
