These steam traps automatically adjust themselves to operate at varying steam pressures, and feature a large condensate discharge capacity for such a compact design. The small size of the traps means less heat and therefore energy is wasted by radiation. For protection against dirt and scale and to prolong trap service life, pipe strainers should be fitted on the inlet side of the trap. Among the wide variety of these traps in types and sizes, the most common types are described along with their specifications.
