Description
The Armstrong International 800-3/4-125 is a Series 800 Cast Iron Inverted Bucket Steam Trap engineered for dependable condensate removal and energy-efficient steam system operation. Built to handle demanding industrial and commercial heating applications, this trap combines rugged cast iron construction with the proven inverted bucket mechanism — one of the most reliable steam trapping technologies available.
The inverted bucket design operates on the principle of buoyancy: steam keeps the bucket afloat and the valve closed, while condensate and non-condensable gases cause the bucket to sink and open the valve for discharge. This continuous, mechanical action ensures efficient condensate removal without wasting live steam, protecting downstream equipment and maximizing system efficiency.
