A purge valve for an evaporative emission control system. The purge valve includes an actuator, a valve body, and a valve closure member disposed in the valve body. The actuator is disposed along a longitudinal axis, and includes an electromagnetic coil having a hollow core extending along the longitudinal axis, a stator disposed in the hollow core, and a permanent magnet armature disposed proximate the stator. The valve body is disposed proximate the actuator, and defines a flow passage extending along the longitudinal axis. When the coil is unenergized, the permanent magnet armature is magnetically attracted to the stator, and the valve closure member is spaced from the armature by a lost motion distance.
