Watts 0038202 Steam Traps

The Watts 0038202 (WTD-600) is a high-performance 3/4" thermodynamic steam trap designed for contractors requiring an economical and rugged solution for steam main drainage, tracing lines, and small process applications. Constructed with an ASTM A743 Grade CA40 stainless steel body, this unit is built to handle superheated steam and environments prone to water hammer. As a direct replacement for the WTD600-3/4, it features a single moving part—a hardened stainless steel disc—that ensures a tight shut-off and effectively discharges condensate at near-saturation temperatures to maximize heat transfer efficiency.

Engineered for high-pressure systems, the Watts WTD-600 series supports a maximum operating pressure of 600 PSI and temperatures reaching 800°F. The compact, lightweight design allows for versatile installation in tight mechanical spaces, while its freeze-resistant properties make it suitable for outdoor applications, such as freeze protection for industrial piping. This stainless steel steam trap is particularly effective in systems where air and non-condensable gases must be purged quickly during startup to prevent system binding.

• Maximum Durability: Robust stainless steel body and cap resist corrosion and thermal shock in high-pressure steam systems.
• Minimal Maintenance: The simplified disc-style design eliminates complex linkages, reducing downtime and replacement parts costs.
• System Efficiency: Provides a tight shut-off to prevent live steam loss, significantly lowering energy consumption in industrial tracing.
• Versatile Application: Ideal for superheated steam, steam mains, and outdoor equipment requiring freeze protection.

Is the WTD-600 suitable for vertical installations?
Yes, this thermodynamic trap can be installed in both horizontal and vertical positions, although horizontal is preferred to ensure optimal drainage and longevity of the disc.

How does this trap handle water hammer?
The Watts 0038202 is specifically designed with a reinforced stainless steel structure to withstand the physical impact of water hammer, which often causes failure in lighter-duty thermostatic traps.

What is the minimum operating pressure for this model?
While rated up to 600 PSI, this 3/4 inch steam trap requires a minimum inlet pressure of 3.5 PSI (0.24 bar) to function correctly and maintain the thermodynamic seal.
