摘要： Disclosed is an exhaust gas recirculation (EGR) valve for vehicles and, more particularly, an EGR valve configured such that an amount of exhaust gas introduced through recirculation is precisely controlled in an early open period of the EGR valve. The EGR valve includes a valve member for opening and closing an EGR channel, a sensor unit for sensing an opening extent of the valve member and outputting an output voltage value corresponding to the opening extent of the valve member, and a controller connected to the sensor unit for recognizing the opening extent of the valve member based on the value output from the sensor unit to control the valve member, wherein a change in the opening extent of the valve member and a change in the value output from the sensor unit are linear, and a linear graph defining the relationship between the opening extent of the valve member and the output value from the sensor unit in a first period, which is an early open period after the valve member opens the EGR channel, and a linear graph defining the relationship between the opening extent of the valve member and the output value from the sensor unit in a second period, in which the valve member is maximally open after the first period, are realized so as to have different slopes.
