Float and thermostatic steam traps FLT147 (Stainless steel DN 40 - 50)

FLT 47 series float traps with built-in air eliminator are designed for modulating condensate discharge, ensuring maximum system heat transfer. Typical applications include unit heaters, heat exchangers, dryers, double wall tanks and other applications where continuous discharge is essential and high flow capacities are involved. Connections are female threaded or flanged, for horizontal or vertical application.


Modulating condensate discharge at steam temperature.

Unaffected by sudden or wide variations in load and pressure.

No condensate backflow.

Excellent air discharge through its integrated vent.

Direction of flow can be easily changed.
