Mepco (Dunham Bush) ML9331 Trap
The Mepco (Dunham Bush) ML9331 is a 1-inch 44-415A Float and Thermostatic Trap engineered for low-pressure steam heating and process equipment applications. Featuring a rugged cast iron body and an H-pattern configuration, this 15 PSI steam trap provides continuous condensate drainage while effectively venting non-condensable gases through its integrated thermostatic air vent. Designed for horizontal installation, the 44 Series F&T trap is a preferred choice for technicians working with heat exchangers, unit heaters, and large steam mains where modulating pressures and varying loads are present.
The internal mechanism utilizes stainless steel for the float, valve pin, and lever assembly to ensure long-term durability and resistance to water hammer. With a high condensate capacity of approximately 2,175 lbs/hr at maximum operating pressure, this model excels in both startup and steady-state conditions. The Mepco 44-415A is designed for easy field servicing, allowing contractors to perform maintenance or replace internal components without removing the trap body from the piping system.
Key Benefits- Optimized Heat Transfer: The thermostatic element quickly discharges air and non-condensable gases, preventing air binding and ensuring maximum system efficiency.
- Heavy-Duty Construction: Features a cast iron body and all-stainless steel internals to withstand demanding industrial and commercial steam environments.
- Versatile Piping: The H-pattern double-inlet/double-outlet design offers flexibility for horizontal pipe configurations and same-side or opposite-side connections.
- Modulating Discharge: Provides immediate drainage of condensate as it forms, maintaining a constant liquid seal to prevent any live steam loss.
What is the maximum operating pressure (MAWP) for the ML9331?
This specific model is rated for a maximum operating pressure of 15 PSIG. For systems exceeding 15 PSI, higher-rated traps in the 44 Series must be used to ensure proper valve orifice sizing and mechanical operation.
Can the 44-415A be used in vertical piping runs?
No, this float and thermostatic trap must be installed in a horizontal orientation with the arrow on the body pointing in the direction of flow. Improper orientation will prevent the float mechanism from opening and closing the valve seat correctly.
Does this trap include a strainer?
While the ML9331 features robust internal parts, it does not include an integral strainer. We recommend installing a separate Y-strainer upstream to protect the valve seat from pipe scale and debris.
