An object is to provide a flow control valve that is capable of reducing or eliminating backlash generated between a male threaded portion and a female threaded portion engaged with the male threaded portion and preventing or eliminating hysteresis in the flow level. The flow control valve includes a body having a fluid inlet and a fluid outlet, a cover attachable to the body, a motor disposed in a space defined by the body and the cover, a valving element connected to a rotary shaft of the motor with a screw member, and an urging member that urges the valving element toward the motor side or toward the side opposite to the motor.
