The Armstrong International 800-3/4-125 Trap is a rugged, cast iron inverted bucket steam trap engineered for superior performance in horizontal piping configurations. Operating at a 125 PSI maximum pressure, this Series 800 flagship model features a 3/4 inch NPT connection and a precision-sized 7/64 inch orifice, making it an ideal choice for high-efficiency condensate drainage in diverse HVACR and industrial steam systems. Utilizing a free-floating stainless steel mechanism, this trap provides consistent automatic air venting at steam temperatures, preventing air binding and ensuring optimal heat transfer. Its unique leverage system effectively multiplies the force provided by the bucket to open the valve against system pressure, resulting in a durable steam trap that resists water hammer and requires minimal maintenance. Because the discharge orifice is located at the top of the unit, dirt and silt are kept in suspension and purged during the discharge cycle, protecting the energy-efficient water seal from live steam loss.

Key Benefits:
  • Enhanced Energy Efficiency: The tight water seal prevents live steam loss, while the robust inverted bucket design ensures long-term operational savings.
  • Superior Reliability: Features a stainless steel internal mechanism with no fixed pivots, significantly reducing friction and wear in high-demand environments.
  • Self-Cleaning Action: The top-mounted orifice design utilizes a full differential purging action to clear dirt and scale, minimizing the risk of clogging.
  • Ease of Maintenance: All Series 800 models are fully repairable, allowing for simple internal replacements without removing the body from the steam line.
  • Resilient Construction: Built with high-quality cast iron, this trap is specifically designed to withstand hydronic shock and heavy-duty industrial steam applications.
Common Questions:
  • What is the maximum operating pressure for this specific Armstrong trap? This model is rated for a maximum pressure of 125 PSI, making it suitable for a variety of low to medium pressure steam systems.
  • Can this trap be used in vertical piping? No, the Series 800 is specifically designed for horizontal installation to maintain the proper water seal and bucket orientation.
  • How does a 7/64" orifice impact performance? The orifice size is calibrated for a maximum capacity of approximately 680 to 700 lbs/hr, balancing flow rates with pressure requirements for efficient condensate removal.
