ABSTRACT A condensate drain valve having a shut-off valve (7) arranged on the low-pressure side, said shut-off valve working in conjunction with a valve seat (10) and being activated by means of a control unit consisting of bimetal elements (4, 5, 6) through a stem (8), said control unit being arranged in the high-pressure area of the condensate drain valve. The bimetal elements (4, 5, 6) abut with one of their ends on fixed (11, 16, 17) thrust pieces and with their other ends on thrust pieces (12, 20, 21) arranged on the stem (8) either directly or through collets (18, 19), the ends of the bimetal elements (4, 5, 6) associated with the stem (8) moving in the direction of closing as the temperature increases, the thrust pieces (11, 12, 16, 17, 20, 21) being so arranged that the shut-off valve (7) coming to rest on the valve seat (10) with- in the lift range of the individual bimetal elements (4, 5, 6). The condensate drain valve can be used in a wide range of pressures without ally inadmissibly high stresses occurring in the bimetal elements (4, 5, 6).
