Resideo MX128LF Valve
The Resideo MX128LF is a heavy-duty 1-1/4 inch lead-free thermostatic mixing valve engineered for high-capacity domestic hot water and hydronic heating systems. Designed for master mixing applications, this large-flow mixing valve provides precise temperature control across a 110°F to 150°F range, making it a standard choice for mechanical contractors managing commercial plumbing systems. The MX Series utilizes a proportional valve with a thermostatic element that reacts dynamically to inlet fluctuations, ensuring stable discharge temperatures even during varying pressure cycles. Constructed from lead-free brass, it meets stringent potable water codes while offering a high CV rating for minimal pressure drop in recirculation loops and point-of-source water heater installations. Whether you are balancing a multi-family residence or a high-demand facility, the Resideo MX128LF Valve delivers the thermal stability required to prevent scalding and maintain system efficiency.
Key Benefits:
- High-Flow Capacity: 1-1/4 inch NPT connections designed for master mixing in high-demand residential and commercial applications.
- Lead-Free Construction: Built with high-quality brass to ensure compliance with modern safe drinking water standards.
- Thermal Stability: Heavy-duty thermostatic element maintains a consistent mixed water temperature despite fluctuating hot/cold supply pressures.
- Dual-Purpose Application: Versatile design suitable for both domestic hot water (DHW) and radiant hydronic distribution.
- Safety Integration: Effectively regulates output to prevent high-temperature exposure and downstream scalding conditions.
Common Questions:
- What is the CV rating of the MX128LF? The 1-1/4" MX Series valve typically features a high CV rating (approximately 9.3) to ensure adequate flow in large-scale recirculation systems.
- Can this valve be used in a hydronic heating loop? Yes, the thermostatic mixing valve is ideal for radiant floor heating or snow-melt systems to maintain supply temperatures within design limits.
- Where should the MX128LF be installed? It is typically installed at the water heater outlet or as a master mixer in mechanical rooms to provide tempered water to the entire facility.
