    The original Moline valves are orificed to limit the amount of steam that enters the radiator at 8 ounces of pressure to about 80% of the condensing capcity of the radiator.  Since all the steam is condensed in the radiator, no trap is needed.    Just keep the pressure below 8 ounces and you'll no problems and incredibly low fule bills and exceptionally even heating.
