Product Description: NIKONiko Free Float Steam TrapBrand: Jiangsu NIKO NikoConnection Type: FlangeMaterial: Cast Iron, Cast Steel, Stainless Steel.Nominal Diameter: DN15-DN100Nominal Pressure: PN16-25Operating Temperature: -2～425℃Product Description;NIKO NikoThe free float steam trap can continuously discharge saturated condensate, preventing water accumulation in heating equipment, thereby achieving the highest thermal efficiency. It is unaffected by steam pressure changes; the float automatically adjusts the opening of the drain valve seat, ensuring continuous operation, stable performance, and good sealing. The stainless steel floats in the free float series are manufactured using advanced grinding processes, offering high precision, excellent sealing performance, and effective air venting. The Y-series components automatically discharge non-condensable cold and hot gases, effectively preventing air locking and ensuring optimal heating efficiency. With a long service life, the entire spherical surface of the float serves as a seal, avoiding concentrated wear during operation. It has low subcooling and allows a high backpressure rate. It continuously discharges condensate with smooth water flow, performing especially well in condensate recovery systems. NIKO Niko Free Float Steam Trap Selection Criteria:Condensate load (discharge capacity in kg/h)*2, maximum working pressure, working pressure difference, valve body material and nominal pressure, connection type and size. The selection factor for condensate load is generally between 2-3. The stainless steel floats in the free float series are manufactured using advanced high-precision grinding processes. The automatic air vent device uses Y-series components that discharge non-condensable hot gases; international brands also use Y-series components. The valve operates on the buoyancy principle: the float rises and falls with the water level based on the amount of condensate, automatically adjusting the opening of the valve seat to continuously discharge condensate. When condensate stops entering, the float descends by its own weight, closing the drain valve seat. Since the drain valve seat is below the condensate level, water and steam are naturally separated, forming a water seal to prevent steam leakage.Used in: Steam heating equipment, condensate recovery systems, and applications requiring rapid condensate discharge. It automatically, quickly, and continuously removes condensate, effectively preventing steam leakage and achieving optimal heating performance. more>
