A novel valve employing hydrophobic and hydrophilic membranes and providing a combined air barrier and liquid sequencing valve. The novel valve is useful in gravitational flow systems and equipment sets for the sequential administration of medical liquids, wherein a primary liquid can be administered at a flow rate independent of the flow rate of a secondary liquid, and includes barriers substantially impervious to air to prevent the inadvertent administration of air when the liquids are depleted.
