Bimetallic Superheat Steam Traps

Bimetallic steam traps have the ability to handle large start-up loads. As the system increases in temperature and pressure, the trap’s stacked nickel-chrome bimetallic elements start to expand, allowing for tight shutoff as steam reaches the trap, thus preventing steam loss.

The bimetallic trap offers resistance to water hammer. A titanium valve and seat on high-pressure bimetallic traps ensure extremely long service life in the harsh environment of superheated steam systems.
