The SFT80 is a large lever float steam trap featuring a heat-resistant cast steel body and cover, along with full stainless steel internals. Its top-inlet bottom-outlet flow design effectively prevents air locking. This trap incorporates a dual balance seat for extended service life, a water seal design for zero live steam leakage, and achieves a back pressure ratio of up to 95%. It is available in three configurations: inline (SFT80), angle-inlet (SFT80A), and offset-inlet (SFT80B).
