Mepco (Dunham Bush) D4664 Trap
The Mepco (Dunham Bush) D4664 3/4" 2E-SW Straight Way Trap is a heavy-duty thermostatic radiator steam trap engineered for high-demand commercial and industrial heating systems. Designed for straight-through piping configurations, this 3/4 inch steam trap effectively manages condensate and air removal to ensure optimal heat transfer in radiators, convectors, and heat exchangers. Built with a rugged bronze body, the 2E-SW model supports a maximum operating pressure of 75 PSI and features a high-capacity air venting mechanism to prevent system binding.
For veteran contractors, the D4664 trap is a reliable choice for maintaining balanced steam distribution and reducing energy loss across two-pipe steam systems. With a substantial condensate capacity of 2,450 lb/hr, it is purpose-built to handle the rigors of large-scale facilities. This unit integrates seamlessly as an OEM replacement steam trap for existing Dunham Bush or Mepco infrastructure, utilizing a durable bellows assembly for precise thermal response. Its compact straight-through design allows for simplified maintenance in tight mechanical rooms without requiring extensive repiping.
Key Benefits:
- High Condensate Capacity: Rated for up to 2,450 lb/hr to ensure efficient drainage in high-output industrial applications.
- Durable Bronze Construction: Robust housing resistant to high-temperature stress and corrosion, standard for commercial HVAC steam traps.
- Optimized Steam Efficiency: Rapidly discharges non-condensable gases and air, increasing overall system thermal efficiency and reducing fuel consumption.
- Straight Pipe Configuration: Simplifies the installation process for straight-way radiator traps in existing steam lines.
- 75 PSI Pressure Rating: Engineered for reliability across a wide range of low to medium-pressure steam heating environments.
Common Questions:
- Is the D4664 compatible with older Dunham Bush systems? Yes, this Mepco unit is the direct technical successor and OEM-compliant replacement for Dunham Bush 2E-SW series traps.
- What is the primary application for a 3/4" straight way trap? It is typically installed in the return line of steam radiators and heat exchangers to selectively vent air and discharge condensate while trapping live steam.
- Does this trap require a specific orientation? The "SW" designation indicates a straight-way flow pattern, making it ideal for horizontal or vertical piping where a straight-through connection is required.
