Disc Steam Traps
Armstrong CD-33 Series controlled disc steam traps extend service life well beyond conventional disc traps through a three-discharge-port design that controls the trap's cycle rate. Built from ASTM A743 GR. CA40 stainless steel, these compact traps handle operating pressures to 600 psig and temperatures to 752°F.

How It Works
The CD-33 Series is designed with three discharge ports, which offer stable disc operation to extend operating life. By reducing the cycle rate, the Armstrong CD-33 Series extends its service life well beyond that of typical disc traps, minimizing maintenance time and greatly reducing steam costs.
The capacities of the Armstrong CD-33 have been engineered specifically for large steam main drips, process equipment, and HVAC heating equipment on constant pressure. The CD-33L (low capacity) trap is designed for steam main drips and steam tracing lines. By ensuring that capacities are designed to suit the application—and are not oversized—the CD-33 Series will last longer than other disc traps with excessive capacity ratings.
