The free float moves up and down in response to the amount of condensate inflow, automatically adjusting the amount of ball valve opening and continuously discharging condensate. This ensures that no condensate accumulates inside the equipment.The surface of the liquid inside the trap is maintained above a certain level and condensate is continually discharged through the orifice. Even when there is no condensate flowing into the trap, the precision free float securely seals closed the orifice. This minimizes steam losses during operation.In free float type steam traps, the forces of the inlet pressure and the back pressure act in opposing directions, so free float traps are able to operate normally even under 90% back pressure. This makes them ideally suited for condensate recovery applications with closed recovery. In contrast, in disc type traps the pressures act in the same direction, so the allowable back pressure is only 50% to 80%.When it is cold before the steam is supplied to the equipment, the X-element is in the contracted position, so its valve opening is wide open and it is in the fully open position. When the supply of steam begins, air and condensate are released through this valve opening, and condensate is discharged through the main valve opening, which is also known as the orifice.When the discharge of the initial air and cold condensate is finished, steam enters the trap causing the X-element to expand, and this expansion closes the valve opening in the automatic air-venting feature. The float rises in response to the inflowing condensate load, and condensate is discharged continually through the orifice.When hot air enters the trap during operation, the X-element immediately senses the drop in temperature inside the trap and opens the valve opening of the automatic air-venting feature, rapidly discharging the air. After the air has been completely discharged, the temperature again rises and the valve opening on the automatic air-venting feature of X-element closes.
