Abstract
A valve for use in an apparatus for supplying molten metal by means of a siphon to a furnace. A valve formed by a tube provided with two flanges is placed at the upper part of the siphon, this tube extending by a certain length below the level of the flanges, so as to form an annular space with each of the branches of the siphon in which the gas is trapped during decanting, which prevents the gaskets from being in contact with the molten metal.
