Spirax Sarco TD42H-L23 Thermodynamic Steam Trap

Spirax Sarco TD42H-L23 Thermodynamic Steam Trap is a stainless-steel, maintainable 3/4 in. thermodynamic steam trap rated for 42 bar (approximately 600 psi) that removes condensate from high-pressure steam lines. The unit features an integral stainless-steel screen and seating assembly designed for reliable condensate separation in demanding steam services, and it includes an integral blowdown valve port to accept a full-port valve for flushing sediment from the screen. As part of Spirax Sarco’s TD42 family, the TD42H-L23 is engineered to protect valves, heat exchangers, and other equipment from carryover while supporting energy efficiency in industrial plants. The 3/4 in. size is well suited for compact headers and branch lines, and the stainless construction delivers durability in hot, corrosive steam environments. Typical applications include process steam headers, steam tracing, and condensate return lines in manufacturing settings where robust, maintainable condensate control is essential.
