Description
The Armstrong International Series 800 Cast Iron Inverted Bucket Steam Trap (Model 800-3/4-150) is a dependable, time-tested solution for steam condensate removal in commercial and industrial HVAC and process piping systems. Built with a rugged cast iron body and engineered to handle operating pressures up to 150 PSI, this trap delivers consistent, efficient performance in demanding steam system applications.
The inverted bucket mechanism is one of the most reliable steam trapping principles available — it opens to discharge condensate and air while snapping shut to prevent live steam loss, helping to maximize system efficiency and reduce energy waste. The #38 orifice is matched to the 150 PSI pressure rating, ensuring optimal condensate discharge capacity for the application.
