Features & Benefits
Thermodynamic Flash Steam Operation
Operates without external power or moving linkage -- the velocity difference between flash steam and condensate naturally lifts and seats the disc, providing reliable self-acting condensate removal.
Compact and Lightweight
Disc-type steam trap is significantly smaller and lighter than equivalent float or bucket traps, reducing pipe support requirements and simplifying installation in tight spaces.
Resistant to Water Hammer
Robust disc and seat design withstands severe water hammer and pressure surges common in steam distribution headers, where float-type traps would fail.
Freeze Resistant
Self-draining vertical body orientation prevents water accumulation and freeze damage in outdoor or unheated installations -- a common failure mode of bucket traps.
In-Line Repairable
Disc and seat can be replaced by removing the bolted cover without removing the trap from the pipeline, reducing maintenance downtime.
Wide Pressure Range
Operates from near-vacuum to 80 bar (1160 psi) with a single disc selection, eliminating the need for multiple trap models across a steam system.
