A condensate valve comprising a housing having a chamber for the accumulation of liquid and an outlet passage from the chamber leading to a central chamber from which liquid is discharged to the atmosphere. A double-acting valve member controls the outlet passage. A diaphragm closes the central chamber and separates it from a pressure chamber. A manually operable device is provided for holding the valve member in a shut-off position or in a position to drain the condensate valve. A separate annular heater assembly is disposed upon the housing in encircling relation to the liquid accumulation chamber to prevent freezing.
