1. A valve for dispensing flowable product from a container, the valve having an upstream end and a downstream end, whereby when the valve is attached to the container and opened, the flowable product is dispensed through the valve in an upstream-to-downstream direction, the valve comprising:
a mounting cup for mounting the valve on the container;
a seal supported on the mounting cup, the seal having an interior surface defining a passage having a longitudinal axis extending in the upstream-to-downstream direction, and a valve seat at an upstream end of the seal; and
a valve stem including
a stem body having a longitudinal axis extending longitudinally within the passage of the seal, wherein at least a longitudinal portion of the stem body is free from engagement with the interior surface of the seal to define an annular longitudinal passage section therebetween,
an upstream portion at an upstream end of the stem body and configured to sealingly engage the valve seat of the seal to inhibit flowable product from flowing into the annular longitudinal portion section, and
a baffle extending radially outward from the stem body at a location downstream of the upstream portion of the valve stem, wherein a radially outer edge margin of the baffle engages the interior surface of the seal at a location downstream of the valve seat to restrict flow of the flowable product between the radially outer edge margin of the baffle and the interior surface of the seal, wherein the baffle defines an opening extending longitudinally therethrough in communication with the annular longitudinal passage section.
