The Armstrong model CD-33L disc trap is built for high-pressure applications, providing a 3/4 NPT connection capable of handling up to 600 psi. This model features an advanced design that controls the cycle rate of the trap, extending service life compared to standard disc traps. Its construction includes three discharge ports designed for improved efficiency and freeze-resistance, alongside a hardened seat and disc.
This trap is well-suited for low-capacity applications like steam main drips and is highly reliable for steam tracing lines.
