The Arco Model K Va'po-Orifice System is- an engineered and coordinated unit which operates to insure equal distribution of warmth. On each radiator there is in stalled a special inlet valve with an adjust able orifice, by means of which flow of steam to each radiator can be accurately calibrated in accordance with the capacity' of the radiator. The adjustment can be made while the system is in operation. Pressure is so controlled that no more steam is admitted to the radiators than they are capable of condensing. Therefore no thermostatic traps are required on the return connections of the radiators. A thermostatic air eliminator equipped with a vacuum check is provided. If the pres sure through inadvertence should exceed the design pressure, steam will enter the return lines, close the vent port of the air eliminator, and the system will auto matically equalize itself, insuring the return of condensate to the boiler. When a zone system is used, the zone valves prevent the self-equalizing action and it is necessary to install an Arco Con densation Pump to insure-the return of condensate to the boiler. Simplicity of design and moderate cost makes possible the installation of this system for little more than the cost of a One Pipe Steam System.
