Description
Hoffman Specialty Series 17C Balanced Pressure Thermostatic Steam Trap
The Hoffman Specialty 401542 (Model 17C-AS-2-25) is a Series 17C Balanced Pressure Thermostatic Steam Trap engineered for reliable, energy-efficient condensate removal in steam heating and process systems. Featuring a 1/2″ NPT angle pattern configuration with a short nipple, this trap is designed for straightforward inline installation in space-constrained piping layouts. With a 25 PSI differential pressure rating, it delivers consistent performance across a broad range of low- to medium-pressure steam applications.
How It Works
The balanced pressure thermostatic operating element responds to the temperature difference between steam and subcooled condensate. The trap remains closed when steam is present and opens automatically to discharge condensate and non-condensable gases — preventing steam loss while maximizing system efficiency and heat transfer.
