A downhole tool comprises a tool housing defining a flow passage therethrough from a first to a second end thereof. A poppet is axially movable on a poppet mandrel positioned in the tool housing. The poppet mandrel has at least one outlet port defined therein. A pilot valve is rotatable about the poppet mandrel. Rotation of the pilot valve opens and closes the at least one outlet port in the poppet mandrel to permit and block flow therethrough, and wherein the opening and closing of the at least one outlet port moves the poppet axially on the poppet mandrel.
