A canister purge valve ( 14 ) includes a housing ( 40 ) defining a fuel vapor flow path between first and second ports. A seat ( 68 ) defines an aperture ( 66 ) through which fuel vapor flow passes to the second port in an open configuration of the purge valve and, in a closed configuration of the purge valve, the aperture is occluded and fuel vapor is prevented from passing to the second port. A stator assembly ( 59 ) has a coil ( 58 ) such that when the coil is energized, a magnetic field is generated. When the coil is de-energized, an armature ( 64 ) engages the seat and occludes the aperture in the closed configuration of the purge valve. When the coil is energized, the armature is attracted to the stator assembly and moves away from engagement with the seat in the open configuration of the purge valve.
