This category covers float steam traps in a range of materials, including cast iron, ductile iron, carbon steel, and stainless steel. Operating on the density differential principle, these products provide continuous high-capacity condensate discharge. They feature an integral air vent and an optional steam lock release device, and are widely used in typical applications such as heat exchangers and automatic temperature-control equipment. When selecting a model, key considerations include the required condensate load, system operating pressure and temperature, as well as compatibility with the pipe material and connection type.
