23843-218 ABSTRACT REFRACTORY STATOR/ROTOR UNIT FOR A VALVE IN THE OUTLET OF A VESSEL CONTAINING A METAL MELT The valve (20) has a tubular stator (21) and a rotor (22) guided by the latter within the vessel as a unit which has at least one transverse opening and an opening (27,24,25,23) starting from it and leading out of the vessel. The rotor (21) for its part is constructed with two tubular portions (25,26), with transverse openings (27,28), which are arranged concentrically with one another and which sealingly extend around the interior and exterior of the stator (21). The transverse openings (24,28), which are preferably of the same size, in the stator and in the inner tubular portion (25) serve to regulate the pouring of the melt whilst the outer tubular portion (26) with its opening (27), which is larger than the others, is constructed as a security closure member. The operational security may be considerably increased with this valve system. (Fig. 1).
