RA 2000 one pipe steam (1PS) thermostatic radiator valve is a three part assembly consisting of a valve body (013G0140), air vent (013L8011) and thermostatic operator (air vent and thermostatic operators are sold separately). The 1PS thermostatic radiator valve assembly is designed to provide accurate temperature control and quiet operation on all "non-vacuum" low pressure (max. 15 psig) one pipe steam heating systems. A temperature change around the thermostatic operator's sensor results in a modulating action of air venting from the radiator or convector. When the thermostatic operator calls for heat, steam enters the radiator and pushes air out through the vent. When the setting temperature is reached, the 1PS valve will be closed and no further air venting takes place. The venting action occurs during each system (boiler) on-cycle only when heat is required. Air will re-enter the radiator during the system off-cycle via a patented "across the seat" vacuum breaker. This eliminates condensate build-up and allows natural system aspiration to occur.Danfoss 013G0140 RA Series Thermostatic Radiator Valve Features:
- The RA 2000 1PS one-pipe steam thermostatic radiator valve provides accurate temperature control and quite operation
- The movement of air across the thermostatic operator effects the modulation control in regulating the venting of air from the radiator or convector
- Based on the set temperature on the operator, the 1PS regulates the amount of steam allowed into the emitter by controlling the amount of air allowed to vent out
- The venting action occurs during each system (boiler) on-cycle only when heat is required. Air will re-enter the system during the boiler off-cycle via a patented "across the seat"
