Claim:
A downhole tool comprising: a body having a bore formed therethrough; a sliding sleeve at least partially disposed in the body; one or more openings disposed about the body at a first end thereof; and a valve assembly and a valve seat assembly at least partially disposed within the bore at a second end thereof, wherein: in a first axial position, the sliding sleeve is adapted to block the one or more openings and maintain the valve assembly in an open position allowing bidirectional flow through the bore; in a second axial position, the sliding sleeve is adapted to close the valve assembly, allowing unidirectional flow through the bore; in a third axial position, the sliding sleeve is adapted to uncover the one or more openings thereby creating one or more of flowpaths between the bore and an exterior surface of the downhole tool, while permitting unidirectional flow through the bore; and the sliding sleeve comprising one or more sleeve apertures that when aligned with the one or more openings disposed about the body, in the third axial position, create the one or more flowpaths.
