Armstrong International 811-1-30 Trap

The Armstrong International 811-1-30 Trap is a professional-grade inverted bucket steam trap designed to optimize the efficiency of steam heating systems and industrial processes. Featuring a robust cast iron body and a 1-inch connection size, this high-performance component is specifically rated for a maximum operating pressure of 30 psi. Engineered for superior condensate removal and effective steam conservation, the model 811 utilizes a unique free-floating stainless steel leverage system. This mechanism eliminates fixed pivots, significantly reducing wear and ensuring reliable intermittent discharge without the risk of sticking or clogging. By maintaining a permanent water seal, the 811-1-30 steam trap prevents live steam loss, while the top-mounted discharge orifice automatically purges dirt and non-condensable gases. Ideally suited for laundry equipment and pressure drip locations, this 1 inch steam trap offers exceptional resistance to water hammer and hydronic shock, providing a dependable solution for industrial steam systems requiring consistent air venting and high-capacity drainage.

• Enhanced Energy Efficiency: The inverted bucket design minimizes live steam loss, contributing to significant operational savings.
• High Resistance to Damage: Built to withstand severe water hammer and corrosive environments common in industrial settings.
• Self-Cleaning Mechanism: The top-mounted orifice ensures that dirt and scale are purged during each discharge cycle, preventing port blockage.
• Field-Repairable Design: Internal components can be serviced without removing the trap from the line, reducing system downtime.
• Continuous Air Venting: Effectively handles non-condensable gases at steam temperature to ensure rapid system startup.

What is the maximum pressure for the 811-1-30 model?
This specific model is designed for a maximum operating pressure (MAWP) of 30 psi, making it ideal for low-pressure steam process applications.

Can this trap be installed in vertical piping?
The Armstrong 811 series is primarily designed for horizontal in-line installation to ensure the bucket mechanism operates correctly with the force of gravity and buoyancy.

Does this trap handle air venting automatically?
Yes, the 811-1-30 features a small vent hole in the top of the bucket that allows air and CO2 to pass through continuously, preventing air binding in your steam system.
