Armstrong International 15B8 Trap

The Armstrong International 15B8 is a high-capacity 2-inch NPT float and thermostatic steam trap engineered for reliable condensate drainage in low-pressure steam systems up to 15 PSI. Constructed with a rugged cast iron body and featuring a 7/8-inch orifice, this Series B trap is specifically designed for industrial heat exchange equipment and HVAC applications where rapid venting of air and non-condensable gases is essential. The integrated thermostatic air vent utilize a balanced pressure phosphor-bronze bellows to ensure immediate air removal during system start-up, preventing air binding and optimizing heat transfer efficiency. With a robust condensate capacity of up to 5,750 lbs/hr, the 15B8 model excels in managing widely varying loads and modulating pressures, providing continuous drainage and maintaining a high standard of performance in demanding steam heating environments. This Armstrong steam trap offers versatile installation with same-side connections, making it an ideal choice for drip legs and heat exchangers where space and piping flexibility are priorities.

• Enhanced Heat Transfer: The 7/8" orifice and continuous drainage design prevent waterlogging in heat exchange equipment.
• Rapid Air Venting: Features a thermostatic air vent that quickly evacuates non-condensable gases to ensure fast system warm-up.
• Industrial Durability: The ASTM A48 Class 30 cast iron construction provides long-term reliability in HVACR and process steam applications.
• Versatile Configuration: Designed for horizontal installation with 2-inch NPT connections for high-flow steam lines.

• Can the Armstrong 15B8 be used in vacuum return systems? Yes, the thermostatic element is designed to respond accurately to pressure-temperature curves even in vacuum conditions.
• What is the maximum operating pressure for this model? This specific 15B8 configuration is rated for a maximum operating pressure of 15 PSI.
• Does this trap require a separate air vent? No, the Series B includes an internal thermostatic air vent to handle air loads automatically.
