Beschreibung
Zusammenfassung:	An electromagnetic valve for use for discharge of molten metal from a container comprises a body (1) providing a discharge passage (2, 3) surrounded by an electrical induction coil (4), the passage having a first portion (2) adjacent the container having a radius greater than that of a second portion (3) extending from the first portion to the discharge end of the passage, whereby the frequency of the electric current supplied to the coil (4) can be chosen independently of the passage discharge diameter.
