Armstrong International 800-3/4-20 Trap

The Armstrong International 800-3/4-20 Trap is a rugged cast iron inverted bucket steam trap engineered for reliable condensate management in horizontal piping configurations. This 3/4" NPT steam trap features a 3/16" orifice designed specifically for systems with a maximum operating pressure of 20 PSI, delivering a continuous discharge capacity of approximately 690 lbs/hr. Built with a free-floating stainless steel mechanism and no fixed pivots, the internal leverage system ensures a tight shut-off and high resistance to wear and water hammer. The top-mounted discharge orifice prevents dirt accumulation, while the unique water seal eliminates live steam loss during operation. For technicians servicing laundry equipment or small process heaters, this industrial steam trap offers consistent air and CO2 venting at steam temperature, preventing air binding and ensuring optimal heat transfer efficiency. Its in-line repairable design allows for simplified maintenance without removing the body from the steam line.

• Efficient Condensate Drainage: The inverted bucket design provides immediate discharge of condensate and non-condensables.
• High Durability: Robust cast iron housing and all-stainless steel internals resist corrosion and hydraulic shock.
• Energy Savings: The water-sealed orifice prevents the escape of live steam, reducing operational costs.
• Minimal Maintenance: The free-floating lever mechanism reduces friction points, significantly extending the service life of the valve and seat.

What is the maximum capacity for the Armstrong 800-3/4-20?
At a 20 PSI differential, this specific model with a 3/16" orifice can handle up to 690 pounds of condensate per hour.

Can this trap handles light loads?
Yes, the Armstrong Series 800 is specifically designed to operate efficiently under light load conditions and against back pressure without losing its prime.

Is the seat and orifice replaceable?
Detailed technical guides confirm that the internal pressure change assembly (PCA) is fully replaceable, allowing for easy field repairs.
