Armstrong International A10564 Float

The Armstrong International A10564 replacement float is a precision-engineered internal component designed for the upkeep and repair of B2, BI2, B3, and BI3 Series Float & Thermostatic (F&T) steam traps. Fabricated from high-grade stainless steel, this spherical float provides the necessary buoyancy to actuate the valve lever mechanism, ensuring efficient condensate discharge without the loss of live steam. In high-pressure steam systems, the mechanical integrity of the float is critical; the A10564 is built to resist water hammer and corrosive environments, maintaining system equilibrium. For contractors performing steam trap maintenance, this float ensures the discharge orifice remains properly modulated based on real-time condensate loads. Precise fitment within the Armstrong F&T trap body prevents short-circuiting and optimizes heat transfer efficiency across the steam loop. This component is essential for restoring trap functionality to factory specifications in commercial and industrial HVACR applications.

• Broad Compatibility: Directly compatible with Armstrong B and BI Series F&T traps for streamlined inventory and field repair.
• Corrosion Resistance: Heavy-duty stainless steel construction prevents premature float failure in harsh chemical environments.
• Optimized Buoyancy: Calibrated weight-to-volume ratio ensures responsive condensate removal under fluctuating pressure loads.
• Durable Design: Engineered to withstand system pressure surges and thermal cycling inherent in industrial steam headers.

How do I identify if an Armstrong A10564 float needs replacement?
Inspect the float for signs of collapse or "water-logging." If the float has a pinhole leak and contains liquid, it will lose buoyancy, causing the steam trap to fail in the closed position, leading to condensate backup.

Is the A10564 float interchangeable across different trap sizes?
This float is specifically designed for the B2, BI2, B3, and BI3 Series. Always verify the orifice size and seat pressure of your specific trap body before installation to ensure the buoyancy lift matches the differential pressure requirements.

What causes a stainless steel float to fail in an F&T trap?
Failures are typically caused by severe water hammer, which can crush the float, or internal erosion due to poor boiler water treatment. Regular inspection of the internal linkage is recommended when replacing the float.
