Mepco (Dunham Bush) ML9634 Repair Kit
As a veteran tech, you know that keeping steam systems at peak efficiency requires reliable components. The Mepco (Dunham Bush) ML9634 Repair Kit is a professional-grade solution engineered specifically for the ML9621 float and thermostatic steam trap. This comprehensive head assembly replacement is designed for the Mepco 40-515 and 44-515 series, providing a direct-fit overhaul for critical internal mechanisms. By utilizing this pre-assembled kit, you bypass the labor-intensive process of individual component replacement in the field. The assembly includes a rugged float mechanism, high-performance air vent, and a precision-cut cover gasket, all mounted to a new cast iron cover. This steam trap rebuild kit ensures consistent condensate drainage and air removal across low-pressure and high-pressure steam applications. Replacing the entire head assembly restores the trap seating surface and mechanical leverage, preventing steam loss and water hammer throughout your hydronic heating system.
Key Benefits
- Direct compatibility with ML9621, 40-515, and 44-515 steam traps.
- Pre-assembled head simplifies installation, requiring only the removal of cover bolts.
- Corrosion-resistant materials ensure durability in harsh commercial steam environments.
- Includes the float mechanism, thermostatic air vent, and replacement gasket for a complete seal.
- Restores condensate capacity and improves overall HVAC system efficiency.
Common Questions
What is included in the ML9634 repair kit?
The ML9634 is a full head assembly. It comes with the cover, float arm and ball, thermal element (air vent), and the necessary body gasket for reinstallation.
Does this kit work for the 40-515 and 44-515 traps?
Yes, this replacement head is the standard service part for both Mepco 40 series and 44 series F&T traps with 1-1/2" or larger connections, commonly identified as the ML9621 model.
How do I know if I need a full head assembly or just a diaphragm?
If the float is waterlogged or the seating surface on the cover is pitted, a full ML9634 assembly is the most cost-effective way to restore the trap to factory specifications without replacing the entire body.
