Product Overview

Armstrong 2010/2011/2022 2000 Series Inverted Bucket Steam Trap requires dedicated connectors for pipeline connection, offering three universal connector options (IS-2, IS-2L, IS-2F) to flexibly accommodate different installation requirements.

The universal connector design allows the steam trap to be quickly and easily installed in pipelines of any orientation. Long-term use requires no major pipeline modifications, retaining the reliability of inverted bucket operating principles while combining the multiple advantages of all stainless steel construction. The product saves energy and offers convenient installation and replacement, making it an ideal choice for steam system condensate drainage.
