Description
The Armstrong International 15B6 is a Series B Cast Iron Float & Thermostatic (F&T) Steam Trap engineered for reliable, continuous condensate discharge in low-pressure steam heating and process systems. With a robust cast iron body, a 1-1/2″ NPT standard connection, and a maximum operating pressure of 15 PSI, this trap is built to handle the demands of commercial and industrial steam distribution with minimal maintenance.
The float mechanism responds immediately to condensate load, providing modulating, continuous discharge that prevents condensate backup and water hammer. The integrated thermostatic air vent automatically purges non-condensable gases and air at startup and during operation, ensuring efficient heat transfer and protecting downstream equipment.
