The invention provides a hydraulic-driven axial flow valve, and belongs to the field of valves. The hydraulic-driven axial flow valve comprises a valve body and a valve element coaxially arranged; thevalve body comprises a water inlet and a water outlet; a guide cavity is formed in the end, near the water outlet, in the valve body; the guide cavity and the inner wall of the valve body are fixedlyarranged through connecting ribs; a tail plug is tightly arranged at the end, near the water outlet, of the guide cavity; one end of the valve element is arranged in the guide cavity, and the two arein tight sliding connection; and the other end of the valve cooperates with the water inlet to control opening and closing of the water inlet. The valve element and the valve body are concentricallyarranged to greatly reduce both vibration and noise caused by turbulent currents; and an inner cavity of the valve body adopts a straight streamline form to greatly reduce the flowing resistance.
