Product Description

CD-3300 Series Disc Steam Traps

All stainless with 360° connector

For pressures to 450 psig (31 barg)
Capacities to 800 lb/hr (363 kg/hr)

The Armstrong CD-3300 is a three-discharge port design, which provides stable disc operation to extend operating life.

The CD-3300 is piped in-line by a 360° universal connector, which allows you to install the trap in virtually any piping configuration. Armstrong’s unique standard connector or our IS-2 connector with integral strainer makes the CD-3300 easy to install, easy to renew. You save on labor time and cost because the connector simplifies piping and remains in-line.

Applications/Usage & Features

Controlled Disc Steam Trap
The Controlled Disc (CD) Steam Trap is a time-delayed device that operates on the velocity principle. It contains only one moving part, the disc itself. Because it is very lightweight and compact, the CD trap meets the needs of many applications where space is limited. In addition to the disc trap’s simplicity and small size, it offers advantages such as resistance to hydraulic shock, the complete discharge of all condensate when open and intermittent operation for a steady purging action.

Operation of controlled disc traps depends on the changes in pressures in the chamber where the disc operates. The Armstrong CD trap will be open as long as cold condensate is flowing. When steam or flash steam reaches the inlet orifice, velocity of flow increases, pulling the disc toward the seat. Increasing pressure in the control chambers snaps the disc closed. The subsequent pressure reduction is necessary for the trap to open. The heating chamber in the cap and a finite machine bleed groove in the disc control the pressure reduction. Once the system is up to temperature, the bleed groove controls the trap cycle rate.

Unique heating chamber
The unique heating chamber in Armstrong’s Controlled Disc Trap surrounds the disc body and control chamber. A controlled bleed from the chamber to the tap outlet controls the cycle rate. That means that the trap design—not ambient conditions—controls the cycle rate. Without this controlling feature, rain, snow and cold ambient conditions would upset the cycle rate of the trap.
