A valve assembly for an exhaust gas recirculation (EGR) system which provides emission control, regulates flow of exhaust gases, and is suitable for gasoline or diesel applications. The EGR valve assembly is a latching valve assembly which reduces power consumption (i.e., continuous electric draw) from the battery while the valve is either being held open or closed, and reduces electrical interference inherent with integrated position sensors. The valve assembly includes a latching mechanism controlled by an actuator which allows a valve to latch open or closed. The valve may be a single stage valve or a multi-stage valve, which includes a latching mechanism that allows for intermediate open positions, and uses of only a short, single pulse of voltage, to change the state of the valve. The actuator may also be held energized at full extend, maintaining a maximum valve open position, creating additional flow capability of the valve assembly.
