The invention relates to a labyrinth minimum flow control valve. The valve comprises a valve body and a valve spool and a valve base which are arranged in the valve body, wherein the valve body is provided with a water inlet and outlet opening. The valve is characterized in that one end of the water inlet and outlet opening is provided with a throttle device, and a labyrinth disc is arranged in the valve body. By adopting the design of diameter-variable unequal flow channels, the labyrinth minimum flow control valve enables the high-pressure liquid to flow along the center of a flow channel, prevents the turbulence caused by the flow along the channel wall, and has the excellent characteristics of cavitation resistance, low noise, high differential pressure endurance and long service life.
