Steam traps Inverted bucket

8

Capacities - DN80 (3") 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 (PS) of the steam trap shall be the relevant D P 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: x 1.5 for continuous use, x 2 to x 3 for intermittent use. b) The effective differential pressure.

Working example:

The unit of choice would have a D P max. differential pressure of 90 bar which is greater than the upstream pressure. For full product selection and nomenclature follow the guide on page 13.

Condensate discharge = 5000 kg/h

Effective differential pressure = 30 bar Upstream pressure = 55 bar g Backpressure = 25 bar g
