Nicholson NTD600-N1B9A Thermodynamic Steam Trap

The Nicholson NTD600-N1B9A Thermodynamic Steam Trap is a compact inline steam trap from the NTD600 family that uses a disk‑type thermodynamic design to drain condensate from steam systems. It features 3/8 in NPT inlet/outlet connections and is rated for 2 to 600 psi service with a maximum temperature of 800°F (427°C).

Constructed for durability in high‑temperature steam service, the trap has a stainless steel body, cap, and disk, and is designed for inline installation with the flow direction indicated by an arrow on the body. The maximum back pressure is 80% of line pressure, a specification that defines its tolerance in condensate return paths.

Typical applications include drip legs, steam heating, and steam tracing, where robust condensate removal is required in steam systems. The Nicholson NTD600 series is offered in sizes from 3/8 to 1 inch, and the NTD600‑N1B9A denotes the 3/8‑inch NPT variant of this lineup.
