Description

The IBV series C inverted bucket steam trap is manufactured

using carbon steel 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.
