Steam Traps operate on difference in density between gas and liquid. Steam enters the inverted submerged bucket and it imparts buoyancy to the bucket, as a result of which, it is lifted and closes the discharge valve. When condensate enters the Trap and reaches a certain level, the weight of the bucket multiplied by leverage exceeds the differential pressure holding the valve to seat and Bucket sinks and opens the valve to discharge condensate. Accumulated air, CO2 and other non-condensable gases are discharged first prior to condensate.
