Float & Thermostatic Steam Traps Series I C and X - Xylem

Automatic and continuous elimination of condensate and air at steam temperature increases system efficiency Float and thermostatic traps operate on the density principle A thermostatic vent in the top of the trap allows free passage of air during start-up and closes near saturation temperature Condensate fills a float chamber causing a float to rise and through a lever mechanism pulls a valve off its seat
