Armstrong International 75A6 Trap

The Armstrong International 75A6 Trap is a heavy-duty cast iron float and thermostatic steam trap engineered for high-capacity industrial applications. Featuring a 1-1/2 inch NPT connection and a precision-engineered 19/64 inch orifice, this Series A trap is designed to handle a maximum operating pressure of 75 PSI. It excels in modulating steam pressure systems, providing continuous condensate drainage and immediate air venting through an integrated thermostatic air vent. The rugged ASTM A48 Class 30 cast iron body and high-strength stainless steel internals ensure reliable performance in demanding HVACR environments. By implementing this F&T steam trap, facility managers can optimize heat transfer efficiency, prevent water hammer, and maintain stable pressure within their steam lines. Whether utilized in unit heaters, heat exchangers, or large coils, the Armstrong 75A6 delivers superior condensate management and long-term durability for peak system performance.

• Optimized Energy Efficiency: The integrated thermostatic vent ensures rapid air removal, facilitating faster startup and improved heat transfer.
• Robust Construction: Built with Class 30 cast iron and stainless steel components to withstand harsh industrial steam conditions.
• Modulating Pressure Handling: Designed to maintain a liquid seal, preventing live steam loss even under varying load conditions.
• High Discharge Capacity: The 19/64" orifice provides reliable condensate removal for medium-pressure steam systems up to 75 PSI.

Common Steam Trap Questions

How do I select the right trap for my steam system? Selecting the correct industrial steam trap requires matching the maximum operating pressure, such as the 75 PSI rating of the 75A6, with your system's peak condensate load and pipe connection size.

Why is my F&T trap leaking live steam? Steam loss often occurs due to dirt buildup or mechanical wear in the orifice. Regular maintenance of the cast iron steam trap internals helps maintain the integrity of the water seal.

What are the benefits of a thermostatic air vent? The built-in vent automatically discharges air and non-condensable gases, which prevents air binding and ensures steam reaches the heat exchange surface efficiently.
