1. A system for isolating a portion of a wellbore comprising:
a housing;
a valve element selectively changeable between
a closed configuration in which the valve element is positioned in a path of fluid flow in the wellbore to define a barrier to fluid flow in the wellbore, and
an open configuration in which the valve element is positioned away from the path of fluid flow in the wellbore;
a deployment sleeve axially moveable within the housing and selectively positioned adjacent the valve element when the valve element is in the open configuration so that the deployment sleeve interferes with the valve element being changed to the closed configuration; and
a retraction sleeve disposed in the housing that is in lifting engagement with the deployment sleeve when the deployment sleeve is positioned adjacent the valve element, the deployment sleeve being axially insertable into the retraction sleeve so that when the retraction sleeve is rotated an elevational force is exerted onto the deployment sleeve to move the deployment sleeve away from the valve element.
