An exhaust gas recirculation valve in a vehicle has two valves that are controlled individually by using one driving source. The exhaust gas recirculation valve enables secure operation of a vehicle even if the driving source is out of order. The exhaust gas recirculation EGR valve includes a driving unit having a driving motor for rotating a motor shaft and an interlocking unit for receiving rotational force from the motor shaft. A rod portion moves upon reception of the rotational force. A valve unit at an end portion of the rod portion controls a flow rate of the exhaust gas. A valve housing is coupled to the driving unit as one unit and has an EGR port and a bypass port. The interlocking unit includes a valve return member for rotating the motor shaft forcibly to make the valve unit to move to an initial position.

The present invention relates to an exhaust gas recirculation (EGR) valve for a vehicle. The EGR valve includes a valve housing connected to an exhaust line for discharging exhaust gas therethrough, having a flow line with an inside area divided for taking and re-circulating a portion of the exhaust gas to a suction manifold, a driving unit on one side of the valve housing, and a valve unit mounted in a flow line of the valve housing for receiving driving force from the driving unit directly to control flows of the exhaust gas flowing through the flow line at the same time individually, thereby making stable control of the exhaust gas flowing through the EGR valve, preventing damage caused by the high temperature exhaust gas, and preventing the exhaust gas from leaking to an outside of the EGR valve.
