Hoffman Specialty Float & Thermostatic Traps

Hoffman Specialty float and thermostatic (F&T) steam traps are available in a wide variety of sizes and pressure ranges. 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. Hoffman Specialty F&T traps are rugged straight-through piping traps meant for low-pressure steam heating applications. The traps are also often used to replace low-pressure bucket traps. All internal parts are stainless steel for long-lasting durability.
