The Armstrong CD-72SR is a disc style trap designed to control the trap’s cycle rate. By reducing the cycle rate, the Armstrong CD-72SR will have a longer service life than typical disc traps. This enhanced performance will ensure that maintenance time is minimized and steam costs are greatly reduced.

The CD-72SR is designed with three discharge ports, which offer stable disc operation to extend trap operating life. The capacity of the Armstrong CD-72SR has been engineered specifically for the following applications: large steam main drips, process equipment, and HVAC heating equipment on constant pressure.


  • Three discharge port design
  • Minimum wear with controlled cycling
  • Freeze-resistant
  • Hardened seat and disc
  • Weldable
