description A valve for use in a wellbore for facilitating a multi-stage stimulation method includes a first sleeve configured to move to open the valve. In addition, the valve includes a second sleeve configured to move to close the valve. The first sleeve and the second sleeve are both movable in a first direction. Movement of the first sleeve a first distance in the first direction opens the valve and subsequent movement of the second sleeve a second distance in the first direction closes the valve. Further, the valve includes a third profile configured to engage a third key of a tool for operating the valve. The third profile is shaped to prevent movement of the tool in a second direction opposite to the first direction when engaged with the third key of the tool.
