TD600 – Non-Repairable Steam Traps

DRIP, TRACING: The TD600 Non-Repairable Steam Traps are commonly used as a drip trap on steam mains and steam supply lines. Ideal for outdoor applications that are subject to freezing and for super heated steam conditions.

The TD600L is Reduced Size Discharge Orifice holes which are preferable in terms of performance, longevity, and efficiency; particularly on pressure over 150 PSI

The TD600 does not have a strainer. (The TD600S models come with a strainer.)

Catalog Spec Sheet



The Thermodynamic Steam Trap is simple and compact with a single moving part (disc) which opens to discharge condensate and closes in the presence of steam. Body materials available are Stainless and Alloy Steels for pressures up to 3,600 psig. Widely used on higher pressure drip applications and critical tracing applications (where condensate back-up is not permitted).

  • Rugged design and excellent for use with superheated steam
  • Operation is easy to check due to distinct cyclic operation
  • Single model operates over a wide pressure range in contrast to mechanical traps
  • Self-draining when mounted vertically to prevent freezing

The primary use of the thermodynamic trap is for draining condensate formed in steam lines (drip applications) with pressures over 30 psig, for pressure under 30 psig thermostatic or F&T traps are generally preferable. For tracing applications that can not tolerate any condensate back-up (referred to as critical tracing) thermodynamic traps are used instead of thermostatic traps. advantages of the thermodynamic trap is that a single model operates over the full pressure range, they can operate on superheated steam, and will self drain preventing frozen pipelines in cold climates.

Thermodynamic Traps are Normally not recommended on process applications because of their limited ability to purge air from the steam system which is required during start-up.
