The artery has more muscle because it is subjected to high blood pressure. The lumen in the vein is bigger because blood pressure is lower so the walls don't need to be thick. The valve in the vein aids to returning blood to the heart because they are open as long as the flow is toward the heart but closed if it is in the opposite direction.
