Inverted bucket steam traps IB30 (11/2” – 2”; DN 40 – DN 50)

The IB30 series inverted bucket steam traps are recommended for applications where the most important requirements are overall operating efficiency and long, trouble-free service life. 

They operate intermittently, either wide open or tightly closed and are, therefore, best suited for medium and high steam pressure applications.
