Description
The Xylem-Hoffman Specialty 402004 is a Series 8C Balanced Pressure Thermostatic Steam Trap engineered for efficient, reliable condensate and air discharge in steam heating and process systems. Featuring a straight-pattern body configuration and a 3/4″ NPT connection, this trap is built for straightforward in-line installation and long-term service life.
The balanced pressure thermostatic operating element responds to the temperature differential between steam and subcooled condensate, opening to discharge condensate and non-condensable gases and closing when live steam is present. This design ensures energy-efficient steam system operation by preventing steam loss while continuously venting air and CO₂ — particularly beneficial during system startup.
Key Features
- Series 8C balanced pressure thermostatic operating principle
