A metering valve for use with a pressurized dispensing container includes a valve stem (1) co-axially slidable within a valve member (2) defining an annular metering chamber (13). The valve stem (1) is provided with a wiper (30) extending radially therefrom to contact an inner surface of the valve member (2) such that, in use, as the valve stem (1) slides axially within the valve member (2), the wiper (30) scrapes the inner surface to remove solid matter disposed thereon.
