A dual-directional normally closed valve (“NC valve”) includes a housing having NC valve first and second passages in fluid communication with a center bore. An armature is provided for selective longitudinally reciprocating motion with respect to the center bore between first and second armature positions. A valve seat is located within the center bore in selective fluid communication with the NC valve first and second passages. A poppet is located at least partially within the housing and is interposed longitudinally between the armature and the valve seat. The poppet is at least partially maintained in engagement with the armature and carried thereby for selective longitudinally reciprocating motion with respect to the valve seat between first and second poppet positions. The poppet defines a dual-directional valving structure cooperatively with the valve seat.
