  • Patent number: 6032725
    Abstract: A rotary steam joint and valve assembly for a steam heated roll includes a non-rotatable, axially slidable sleeve journaled on one of the roll shaft ends and operable to selectively withdraw condensate which pools in the lower part of the roll when the roll is stopped or operating at low speed. At higher roll speeds, when condensate is more uniformly distributed circumferentially around the roll interior, the valve is operable to open all radial condensate return paths to the concentrate discharge port in the shaft end. Steam is supplied radially to the shaft end and the valve is constructed to permit steam flow in either position of the valve.
