MW-2548
The MW-2548 is a control group for use with a manifold in underfloor heating applications.
The mixing valve on the MW-2548 is adjustable between 20°–65°C, which complies with the requirements of BS1264-4:2009 for initial warm-up temperatures of 20°–25°C.
It also includes a locking pin to set the maximum blend temperature.
MW-2548 Mixing Unit
The MW-2548 features an additional probe pocket for installing an optional over-temperature device, a throttle to increase the Kv of the mixing valve for larger systems, and a built-in non-return valve above the circulation pump. This prevents backfilling during system filling and reduces water loss if the circulation pump needs to be removed for maintenance.
Features and Benefits
- Advanced technology provides long-lasting, reliable performance.
- Precision-engineered materials and high-efficiency pump ensure durability.
- Inclusive temperature control ensures water temperatures entering the floor do not exceed design limits.
- Built-in thermostatic actuator with a temperature range of 20°–65 °C.
- Integrated flow rate control valve for improved flow regulation.
- Standard 210 mm manifold spacing and 1″ BSP connections allow broad compatibility.
- Optimized system design for all floor constructions and manifold products.
