The valve comprises a valve body (16,18) defining a metering chamber (17), an outer annular seal (21) closing an outer end of the chamber (17), an inner annular seal (20) at an inner end of the chamber (17) and a valve stem (15) extending in sliding sealed relation through the chamber (17) and engaging at its inner end a valve stem member. Spring means (31) are provided urging the valve stem member (29) into sealing engagement with the inner seal (20) such that the chamber (17) is sealed, the valve stem (15) being manually movable against the action of the spring means (31) to unseat the valve stem member (29) into a first position in which a fluid inlet path is opened into the chamber (17) to enable filling of the chamber (17).
