A valve device for transferring waste oil from a reservoir to an emptied oil vending container having a threaded neck includes a vertical barrel having a rotatable fluid-directing member and an entrance tube horizontally emergent from the barrel and extending to a distal extremity. The lower extremity of the barrel is equipped with an annular closure cap adapted to make fluid-tight joinder with the threaded neck. The distal extremity of the entrance tube is adapted to make fluid-tight joinder with the reservoir.
