Thermodynamic Steam Traps (also called Thermokinetic Traps) work with only one moving part - a stainless steel disc that cycles based on the pressure and velocity of steam or condensate. Over time, the disc eventually wears out and requires replacement for the steam trap to continue to work properly.
