Description
The Spirax-Sarco TD42L is a heavy-duty thermodynamic disc steam trap constructed in stainless steel, engineered for reliable and efficient condensate removal in a wide range of industrial and commercial steam distribution systems. With a 3/4″ NPT connection, this trap is well-suited for steam mains, tracer lines, and process applications where durability and long service life are essential.
Thermodynamic Disc Operation
The TD42L operates on the thermodynamic disc principle, using the difference in velocity and pressure between flash steam and condensate to open and close the valve disc. This simple, robust design features no bellows, floats, or levers — resulting in fewer moving parts, reduced maintenance requirements, and consistent performance across varying load conditions.
Stainless Steel Construction
The all-stainless steel body provides outstanding resistance to corrosion, oxidation, and the harsh conditions found in high-pressure steam environments. This makes the TD42L an ideal choice for applications where longevity and material integrity are critical priorities.
