An axially actuated valve for use in a pressurized container is controlled by a user to dispense the amount of product desired. The valve stem is moved in an up and down direction so that when dispensing, the user can control the amount of the valve openings that are in communication with the material to be dispensed. A resilient sealing grommet provides an interference fit around the lower part of the valve stem from the button up to the top of the valve stem openings. This interference fit effectively closes off the uncovered portion of the valve openings thereby permitting user control of the dispensing rate. The stem has openings partially tapered in the form of an inverted truncated pyramid to further facilitate user control of the dispensing of product.
