Beschreibung
Zusammenfassung:	Disclosed is an exhaust gas recirculation (EGR) valve for a vehicle which achieves regulation of the flow rate of exhaust gas introduced into an engine and the flow rate of fresh air. The EGR valve includes a fresh air flow channel (110), an EGR flow channel (120) connected to the fresh air flow channel (110) and a valve unit (200) configured to open or close the EGR flow channel (120) and to selectively block the fresh air flow channel (110) according to an opened/closed state of the EGR flow channel (120). The valve unit (200) includes a first valve (210) to open or close the EGR flow channel (110) and a second valve (220) arranged at one side of the first valve (210) at a different angle from an arrangement angle of the first valve (210). The second valve (220) is moved along with the first valve (210) to selectively interfere with a flow stream of fresh air in the fresh air flow channel (110).
