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
