Spirax Sarco TD42L L16 W Thermodynamic Steam Trap

The Spirax Sarco TD42L L16 W Thermodynamic Steam Trap is a 1-inch steel steam trap with a blowdown valve, part of Spirax Sarco’s maintainable TD42L family designed for condensate removal in steam systems and for use on small- to mid-sized steam lines where quick, reliable drainage is essential. TD42L traps are maintainable and feature an integral strainer, allowing inspection and cleaning without removing the entire valve assembly, which reduces downtime during routine maintenance and helps keep condensate paths clear in systems with fine controls. The mechanism relies on a disc to regulate condensate discharge and trap steam, a hallmark of Thermodynamic traps, enabling fast drainage when condensate accumulates while minimizing loss of live steam under typical operating conditions. With a 1-inch steel body and built-in blowdown valve, this variant offers straightforward venting and flushing, making it suitable for compact heating coils, surface condensers, and other small steam-using equipment where dependable condensate removal is needed.
