An automatic steam trap that utilizes a floating disc located in a sealed control chamber to open and close inlet and outlet ports in the floor of the control chamber for steam and for air and/or condensate respectively. The disc moves in response to the pressure condition in the chamber between a closed position sealing off the ports and an open position spaced away from the ports. The movement of the disc to its open position is limited by a tubular spacer in the control chamber with spaced projections engageable with the outer margin of the top surface of the disc. The spaces between the projections permit fluid to pass from the lower portion of the control chamber below the disc to the upper portion of the control chamber above the disc so that fluid pressure can act against the top surface of the disc.
