• Usage
• Steam Trap Product Introduction & Technical Specifications 1. Product Overview A steam trap, also known as a steam separator, is a critical automatic valve in steam systems. It automatically discharges condensate, air and non-condensable gases while effectively preventing steam leakage. Its core functions include ensuring efficient heat transfer of steam equipment, preventing pipeline water hammer, avoiding equipment corrosion, and saving steam energy. It is widely used in all industrial and civil fields that use steam, such as petrochemical, power, food, textile, and HVAC industries. 2.
