Hoffman 650AY Steam Trap

Hoffman 650AY Steam Trap is a compact, 1-inch NPT steam trap designed for use in mid- to high-pressure steam systems. With a operating range of 10 to 600 psi, this model suits commercial and light industrial heating circuits where reliable condensate management is essential. The 650AY variant sits within Hoffman's Specialty line of steam traps and uses standard 1" NPT connections that simplify installation into common piping layouts. As a purpose-built steam trap, it is intended to separate condensate from live steam and protect downstream equipment by maintaining appropriate steam quality across a broad pressure range. The AY suffix denotes a specific configuration within the 650-series lineup, differentiating it from other model variants. Typical applications include steam distribution networks in buildings, process heating, and radiant or unit heaters that rely on consistent condensate control to maintain system efficiency and performance. With its 1-inch NPT connections, the 650AY fits standard piping and allows straightforward integration into existing steam loops.
