The invention relates to improvements in metering valves for use in dispensing apparatus. There is provided a metering valve (10) for assembly with a pressurised dispensing container (not shown). The valve (10) comprises a valve stem (20) co-axially slidable within a valve body (16, 17) defining a metering chamber. Inner and outer seals (15, 18) are provided for sealing between the valve body and the valve stem and a gasket (14) is located on the valve body for sealing against a neck portion of a pressurised dispensing container. At least one of the inner seal, outer seal or gasket is formed as a co-moulding with at least part of the valve body.
