The invention discloses an adjustable and controllable ball valve, and relates to the technical field of ball valves, the adjustable and controllable ball valve comprises a first shell and a second shell, after the first shell and the second shell are connected, a passage is formed inside, a valve element is installed in the first shell, and a first driving assembly used for controlling the valve element to rotate is arranged on the first shell; a pressure reducing assembly is arranged in the second shell and used for reducing the water pressure in the channel before the channel is blocked by the valve element. In the process of closing the valve, the first pressure reducing plate can form a pressure reducing state before the valve element is blocked by pulling the pull rod part, so that the impact force of water flow on the valve element is reduced, and the service life of the valve is prolonged. Meanwhile, the two second pressure reducing plates form a flow dividing state before the first pressure reducing
