Abstract

In one aspect, a valve includes a valve body rotatable about a central axis of the valve body, an interior channel adjacent the valve body for permitting a fluid to flow through an axial opening of the interior channel, and a plug within the interior channel that is movable between a first axial position at the axial opening and a second axial position spaced apart from the axial opening. In the first axial position, the plug closes the axial opening to prevent the fluid from flowing through the axial opening in a first direction and to prevent the fluid from flowing through the axial opening in a second direction that is opposite to the first direction. In the second axial position, the plug permits the fluid to flow through the axial opening into the interior channel in the first direction.
