Ball float steam trap is a mechanical steam trap that automatically opens and closes by means of a float rising and falling with the condensate level. It can continuously discharge saturated condensate with excellent steam locking performance, large drainage capacity and stable operation. The product adopts a precision float opening and closing structure, which can work stably under low and variable load conditions, effectively avoid steam loss, and features fast start-up, no air locking and water hammer resistance.It is suitable for heat exchangers, heating equipment, main steam pipelines, large heat-consuming equipment and other working conditions, and is widely used in industrial thermal systems with high drainage requirements such as petrochemical, power, textile, paper-making and food processing.
