Product Overview
The SPIRAX SARCO TD42L is a high-performance thermodynamic steam trap engineered for efficient condensate discharge and steam containment in industrial process systems. Operating on the thermodynamic principle, this valve utilizes the dynamic action of a disc and seat arrangement to discharge condensate at near-steam temperature while preventing live steam loss. The TD42L is a direct replacement for the TD42 series, featuring an upgraded internal design for enhanced durability and resistance to water hammer and superheat conditions. Its compact, robust construction makes it ideal for demanding applications in steam distribution, tracing, and process heating lines.
