Armstrong International 812-3/4-125 Steam Trap

The Armstrong International 812-3/4-125 Steam Trap is a high-performance inverted bucket steam trap engineered for superior condensate drainage in industrial steam systems. Constructed with a rugged cast iron steam trap body, this Series 812 model features a 3/4 inch NPT connection and is specifically designed to operate at a maximum pressure of 125 PSI. Utilizing a precision-engineered 5/32 inch orifice, it ensures efficient heat transfer by continuously discharging air and non-condensable gases alongside condensate. Its unique leverage system provides high capacity for its compact size, making it a reliable solution for process equipment, unit heaters, and steam tracing lines. By preventing steam loss and resisting water hammer, this industrial steam trap optimizes energy efficiency and maintains system integrity. Designed for vertical installation, the Armstrong 812 series is the industry standard for durability and consistent performance in demanding HVACR and mechanical environments.

Key Benefits:

• Effective condensate management ensures dry steam and prevents water hammer damage.
• Inverted bucket design provides excellent resistance to wear and corrosion for long-term reliability.
• The 5/32 inch orifice is precision-calibrated for optimal discharge at 125 PSI.
• Continuous air venting during the operation cycle improves overall thermal efficiency.
• Durable cast iron construction is suitable for a wide range of industrial steam applications.

Common Questions:

What is the maximum operating pressure for the Armstrong 812-3/4-125?
This specific model is rated for a maximum allowable pressure of 125 PSI, ensuring safe operation within its designated pressure curve.

How does the inverted bucket mechanism improve efficiency?
The mechanism uses the buoyancy of steam to close the valve while allowing condensate and air to escape, preventing energy-wasting steam leaks.

Can this steam trap handle air during startup?
Yes, the 812 series is designed to vent air and non-condensable gases automatically, which prevents air binding and ensures rapid system heat-up.
