The free float steam trap does not have any levers or joints inside. The float is the only moving component. The floats used in this type of steam trap are made of high quality stainless steel with very low dimensional tolerances.

Features of free float steam traps
The cost saving advantage of free float steam traps
1. Low equipment and installation costs
2. Small size, so take up very little space
3. With filter, so no additional filters are needed
4. Because the float is the only active component, the probability of failure is very low
5. Low maintenance costs
6. Good resistance to water hammer, so no leverage and other connections are needed

How it works
When steam enters the trap, the entrained cold air is first discharged from the exhaust valve port. Subsequently, the condensed water enters the steam trap, and buoyancy causes the float to rise, thereby opening the drain valve and allowing the condensate to drain. Equipment (heat exchangers, etc.) has reached a higher operating temperature due to condensate discharge. At this point, the condensate and steam enter the trap together, and the heated air closes the exhaust valve port, preventing steam from escaping. Thereafter, the float can be adjusted according to the flow rate.
In order to prevent steam leakage in the steam trap, in addition to the metal-to-metal connection to provide sealing, the water level maintained on the drain valve can also provide a good water seal.
For the condensate discharge process of the drying drum, if the steam blocks the valve before the condensed water is discharged, the bypass valve on the bonnet is opened to allow the steam to escape.
