The armature is moveable relative to a valve seat and the valve includes an armature stop received in the internal passage with a press-fit so that it is engaged by the armature in one position of the armature to limit movement of the armature away from the valve seat. The valve also has a biasing member located at least partially between the armature and the armature stop, the armature has a reduced diameter portion received at least partially within the biasing member, and wherein the reduced diameter portion engages the armature stop in the open position of the valve.
