Float and thermostatic (F&T) steam traps are found at the end of steam mains, long piping runs, and steam heating equipment that produce large quantities of heat such as unit heaters, heat exchangers, etc. Composed of a valve mechanism assembly with seat, internal thermostatic air vent and a stainless steel float. F&T traps work well on both light and heavy loads of steam heat generated condensate. These traps are meant for low-pressure (15 psi or less) steam heating systems as well as higher steam pressures up to 175 psi. F&T traps feature separate orifices for condensate and air, which provide continuous condensate drainage and air venting even under conditions of zero pressure. A level connects the ball float to the valve and seat. Once condensate reaches a certain level in the trap, the float rises, opening the orifice and draining condensate. A water seal formed by the condensate prevents live steam loss. Since the discharge valve is under water, it is not capable of venting air and non-condensables. When the accumulation of air and con-condensable gases causes a significant temperature drop, a thermostatic air vent in the top of the trap discharges them.
