Armstrong International 800-1/2-125 Trap

The Armstrong International 800-1/2-125 is a high-performance inverted bucket steam trap engineered for superior condensate management in industrial HVACR and steam process applications. Constructed from rugged cast iron, this 800 Series steam trap features a 1/2" NPT connection and is specifically calibrated for a 125 PSI maximum operating pressure with a 7/64" orifice. Unlike other designs, the inverted bucket mechanism is positioned at the top of the body, allowing dirt particles to remain in suspension until they are purged, effectively preventing orifice clogging. This model provides continuous automatic air venting and CO2 removal at steam temperature, ensuring optimized heat transfer and preventing air binding. Designed for horizontal installation, the stainless steel valve and seat are precision-lapped to provide a bubble-tight seal that resists the erosive effects of water hammer. This trap is fully repairable in-line, offering significant long-term operational savings by allowing for the replacement of internal components without disturbing existing pipework.

• Efficient Condensate Drainage: The inverted bucket design ensures rapid removal of condensate to maintain system thermal efficiency.
• Rugged Durability: Features an ASTM A48 Class 30 cast iron body and corrosion-resistant stainless steel internals for harsh environments.
• Advanced Air Venting: Continuous automatic air venting prevents the buildup of non-condensable gases, reducing the risk of corrosion.
• Maintenance Friendly: The 800-1/2-125 trap is designed for easy in-line repair, minimizing labor costs and system downtime.
• Water Hammer Resistance: The open-bottom bucket design provides inherent protection against the damaging effects of sudden pressure surges.

How do I troubleshoot an Armstrong 800 steam trap that is blowing live steam?
If the trap fails to close, check for a lost prime, a clogged orifice, or an oversized orifice for the current system pressure. Ensure the 7/64" orifice is appropriate for your 125 PSI application.

What is the maximum back pressure for the Series 800 trap?
The Armstrong 800 Series is highly resistant to back pressure, typically operating effectively even when back pressure reaches up to 99% of the inlet pressure.

Can the Armstrong 800-1/2-125 be used on superheated steam lines?
Yes, inverted bucket steam traps are well-suited for superheated steam applications as they maintain a water seal that protects the discharge orifice from live steam loss.
