Description

The IBV series C-LF2 inverted bucket steam trap is manufactured

using carbon steel (A350 LF2) for the body and cover; with

internal components being made of stainless steel. It is suitable

for use with saturated and superheated steam and in high

pressure and high temperature applications. The IBV is fully

automatic and has been designed in such a way that there is

minimal friction from mechanism movement; valve closure is

immediate, without any steam loss and the discharge action is

positive with no equivocal phases.

On the cover of the IBV there in a " hole, threaded and

plugged, to eliminate any water discharge after being hydraulically

tested before leaving the factory. This hole can be reopened on

site for the customer to perform periodic hydro testing.
