Armstrong International 880-3/4-125 Trap

The Armstrong International 880-3/4-125 is a high-performance inverted bucket steam trap designed for horizontal installation in demanding HVACR and industrial steam systems. Engineered with a rugged cast iron body (ASTM A48 Class 30), this Series 880 model features an integral strainer that effectively protects the internal mechanism from scale and debris. Operating with a 7/64" orifice, it is rated for a maximum pressure of 125 PSI, ensuring efficient condensate drainage and preventing live steam loss through its reliable water seal. Evolution in trap design allows this unit to provide continuous automatic air venting at steam temperature, while its free-floating stainless steel leverage system eliminates fixed pivots to minimize wear and friction. This 3/4" NPT trap is highly resistant to water hammer and is a preferred choice for energy-saving steam trapping applications where long-term reliability and repairability are essential for reducing operational overhead.

Key Benefits:

• Efficient Condensate Drainage: Uses an inverted bucket mechanism to ensure thorough removal of condensate without backup.
• Enhanced Protection: The integral strainer prevents dirt and scale from clogging the 7/64" orifice.
• Energy Savings: A robust water seal prevents live steam loss, directly improving system thermal efficiency.
• Reduced Maintenance: The free-floating stainless steel internals are designed for longevity and are fully repairable.
• Air & CO2 Venting: Continuous venting at steam temperature prevents air binding and corrosion.

Common Questions:

How do I install the Armstrong 880 steam trap?
This model is designed for horizontal installation. Ensure the trap is level to allow the inverted bucket to operate correctly and utilize the side-inlet/side-outlet 3/4" NPT connections.

What is the maximum operating pressure for this model?
The Armstrong 880-3/4-125 is specifically calibrated for systems with a maximum operating pressure of 125 PSI.

Can the internal components be replaced?
Yes, the Series 880 is fully repairable. You can replace the stainless steel valve, seat, and bucket mechanism to extend the service life of the cast iron housing.
