Steam traps

Inverted bucket

Capacities - DN20

Note: IBV inverted bucket steam traps should be selected for use at the most

appropriate working differential pressure and not on the basis of load.

Condensate discharge capacities (kg / h) - The discharge capacities in the table are

referring to the operating temperature of the saturated steam and the PMO of the steam

trap shall be the relevant DP maximum differential pressure of each specific model.

For optimum trap selection you need to know the following criteria:

a) The hourly amount of condensate to be discharged, inclusive of the safety factor:

x1.5forcontinuoususe, x2 to x3forintermittentuse.

b) The effective differential pressure.

Working example:

Condensate discharge = 1050 kg /h

Effective differential pressure = 30 bar

Upstream pressure = 45 bar g

Backpressure = 15 bar g

The unit of choice would have a DP max.

differential pressure of 55 bar which is

greater than the upstream pressure.
