The invention provides for a valve assembly for a printhead cartridge. The valve assembly includes a flanged valve stem defining an inlet opening with a skirt engaging portion for operatively engaging an outlet port of the cartridge. The valve assembly also includes a depressible valve member within the stem, and a pressure regulator having a spacer with a central hub, a diaphragm with central inlet opening, and a clip defining an outlet opening. The clip is configured to operatively engage the valve stem to sandwich the valve member, spacer and diaphragm between the valve stem and clip, so that ink from the cartridge is able to flow into the inlet opening and exit via the outlet opening when the valve is open.
