Wenzhou Wofer Valve Co., Ltd. presents the premium CS11H Free Floating Ball Type Steam Trap, a mechanical steam trap designed for continuous, reliable condensate discharge with zero steam leakage in low to medium pressure steam systems. This advanced free floating ball steam trap operates on the buoyancy principle: a precision-ground stainless steel hollow floating ball rises and falls with condensate level changes, automatically modulating the seat opening for smooth, continuous drainage without water accumulation—ensuring maximum thermal efficiency and stable performance even under fluctuating steam pressures.
The simple, robust design features only one moving part (the stainless steel float), with no wearing components, delivering long service life, excellent air venting (via built-in or manual device), no air locking, silent operation, and near-zero subcooling (≈0°C). The valve seat remains below the condensate level, forming a natural water seal that prevents live steam loss.
