ABSTRACT:
There is provided a steam trap having a thermal control element arranged on the high-pressure side containing an expanding medium and a shut-off unit closing in the direction of flow. The shut-off unit includes two closure members and two valve seats forming two series-connected, independent sealing units, which are opened or closed one after the other in series fashion by the control element so as to reduce wear of the shut-off unit. The two sealing units are arranged in a single assembly which is coupled to the control element for ease of installation.
