Abstract:
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.
