FAQ

What is the main advantage of a free float steam trap design like the SJ3FNX-22?

The primary advantage is its ability to continuously discharge condensate. The free float rises and falls with the condensate level, opening the valve orifice proportionally. This ensures no condensate backup, preventing water hammer and improving heat transfer efficiency in the system.

The body material, GGC40.3 (Nodular Graphite Cast Iron), combined with the specified maximum operating temperature (TMO) of 220 deg C, makes it suitable for many saturated steam applications. For superheated steam, you must always verify that the operating temperature and pressure do not exceed the manufacturer's specified limits for the component.

Correct operation can be checked using several methods. The simplest is listening for the sound of continuous condensate discharge using an ultrasonic tester or a mechanic's stethoscope. A temperature check on the pipe upstream and downstream of the trap can also indicate its function; a significant temperature drop after the trap suggests it is working correctly.
