Armstrong International 15B4 Trap

The Armstrong International 15B4 Trap is a high-performance Series B Cast Iron Float & Thermostatic Steam Trap engineered for heavy-duty industrial and commercial heating applications. Designed with a 1" NPT Standard Connection and a 5/16" orifice, this unit excels in managing high condensate loads while maintaining a maximum operating pressure of 15 PSI. Featuring an integrated thermostatic air vent, the 15B4 ensures rapid air removal for quick system start-ups and optimal heat transfer efficiency. Its rugged cast iron construction provides exceptional durability in demanding HVACR environments, making it a preferred choice for low pressure steam systems, unit heaters, and heat exchangers. By utilizing a mechanical float mechanism, it provides continuous drainage of condensate, preventing water hammer and ensuring the reliability of your steam infrastructure. This F&T steam trap is specifically designed for maintainability and long-term service in critical temperature control processes.

• Efficient Condensate Drainage: The 5/16" orifice allows for high-capacity discharge, maintaining dry steam lines and maximizing thermal efficiency.
• Rapid Air Venting: Equipped with a balanced-pressure thermostatic air vent to handle large volumes of non-condensable gases during start-up.
• Durable Cast Iron Construction: Built to withstand the rigors of industrial steam service with a robust Series B body design.
• System Protection: Helps eliminate water hammer and improves the overall performance of industrial steam heating equipment.
• Versatile Application: Ideal for 1" NPT piping configurations requiring low-pressure steam trap solutions.

How does a float and thermostatic steam trap work?
The float responds to the condensate level, opening the valve to discharge liquid, while the thermostatic element handles air and non-condensable gases independently.

What is the maximum pressure for the Armstrong 15B4?
This specific model is designed for low-pressure applications with a 15 PSI maximum operating pressure limit.

Can the 15B4 be used on unit heaters?
Yes, the Armstrong 15B4 is highly effective for unit heaters and other constant-pressure applications where rapid condensate removal is essential.
