Spirax Sarco BPT13S Pressure Thermostatic Steam Trap

Spirax Sarco BPT13S is a brass-bodied, balanced‑pressure thermostatic steam trap with 1/2 in NPT screwed connections, designed for automatic condensate drainage in steam systems. Its thermostatic capsule responds to condensate temperature to open and discharge moisture while minimizing live steam loss during startup and normal operation. The unit is rated for a maximum operating pressure of 16 bar g, making it suitable for steam mains, jacketed vessels, and heat exchangers where reliable condensate removal is essential. Typical applications include condensate return lines, steam distribution headers, and equipment requiring efficient moisture separation, all backed by Spirax Sarco’s maintainable design that allows capsule and seat assemblies to be serviced or replaced to extend service life.
