Abstract: A multi-functional flow control valve for a water treatment system includes a valve body having a water inlet port, a water outlet port and an effluent outlet. A valve core connected with a valve rod is placed inside the valve body. The valve body defines a flow channel therein for connecting with an inside and an outside of a filter element of the water treatment system, respectively. The valve core includes a moving valve disk and a fixed valve disk whose head faces are aligned hermetically rotationally. The moving valve disk is connected to the valve rod. The fixed valve disk defines a plurality of through holes which are connected to the water inlet port, the water outlet port and the effluent outlet, respectively. The moving valve disk defines a through hole and two blind recesses therein.
