Description
Armstrong International 125A8 Series A Float & Thermostatic Steam Trap
The Armstrong International 125A8 is a Series A Cast Iron Float & Thermostatic (F&T) Steam Trap engineered for reliable, continuous condensate discharge in commercial and industrial steam systems. Featuring a standard 2″ NPT connection and a maximum working pressure of 125 PSI, this trap is built to handle demanding steam distribution and process heating applications with long-lasting dependability.
Product Overview
Float & Thermostatic steam traps combine the continuous modulating action of a float valve with a thermostatic air vent, making them ideal for applications where both condensate and non-condensable gases must be efficiently removed. The Armstrong 125A8 delivers immediate, continuous condensate drainage while the integrated thermostatic air vent purges air and CO₂ at startup and during operation — protecting system efficiency and preventing water hammer.
