Abstract
The present invention relates to a flow control valve that is capable of rapidly supplying hot water at a user's desired temperature by promptly controlling the opening rate of a valve depending on the flow of supplied direct water. In order to implement this, the flow control valve according to the present invention includes a motor that rotates in both directions; an opening and closing member that reciprocates by rotation of the motor to control the opening rate of a channel; a position varying member of which a position varies integrally with the opening and closing member by the rotation of the motor; and a valve opening rate sensing unit that senses the opening rate of the valve from an output voltage varying depending on the position of the position varying member.
