Mepco (Dunham Bush) ML9621 Trap
The Mepco (Dunham Bush) ML9621 Trap is a heavy-duty 1 1/4" float and thermostatic steam trap engineered for reliable condensate drainage in low-pressure steam systems up to 15 PSI. This 44-515A F & T trap features a robust cast iron body and high-grade stainless steel internal components, including a precision-lapped valve and seat assembly. Designed for high-capacity loads of up to 2,700 lbs/hr, the Mepco ML9621 utilizes a dual-port H-pattern configuration, allowing for flexible same-side piping in tight mechanical rooms. The integrated thermostatic air vent ensures rapid discharge of air and non-condensable gases during cold startups, while the modulating ball float mechanism provides continuous drainage to prevent water hammer. For technicians performing steam trap maintenance on larger heat exchangers, air handling coils, or unit heaters, this 44 Series model is a drop-in replacement for legacy Dunham Bush 40 Series units, offering improved versatility with its four-port design.
Key Benefits:- High Condensate Capacity: Handles up to 2,700 pounds per hour at 15 PSI maximum operating pressure.
- H-Pattern Versatility: Features double inlets and double outlets for flexible piping and simplified HVAC repair.
- Durable Construction: Cast iron housing with stainless steel float and valve internals for long-term industrial service.
- Efficient Air Venting: Balanced pressure thermostatic element handles large air volumes and operates against back pressure.
- Modular Design: Facilitates easy hvac maintenance with head assemblies that can be replaced without breaking main piping connections.
What is the maximum pressure for the 44-515A model?
The Mepco ML9621 is specifically rated for a maximum operating pressure (PMO) of 15 PSI, making it ideal for low-pressure steam mains and process equipment.
Can I use this to replace an older Dunham Bush 40 series trap?
Yes, the 44 Series is the direct successor to the 40 Series. Its four-port configuration makes it a commercial hvac standard for retrofitting older same-side or opposite-side piping layouts.
Why is my F & T trap cold while the system is under pressure?
A cold trap usually indicates it has failed in the closed position or is air-bound. Regular hvac inspection of the thermostatic vent and float mechanism is required to ensure continuous condensate flow.
