3-way mixing valve, flanged, angled passage, DN 40, PN6, kv=25 DR40FA

Mixing valve – precise regulation in heating and air conditioning systems

This flanged 3-way valve, with a DN 40 diameter and PN6 pressure class, is a reliable solution for mixing liquid streams in heating and air conditioning systems. Its GG20 cast iron construction ensures durability and corrosion resistance, and the constant percentage flow characteristic guarantees precise temperature control. This valve is particularly useful in installations using water or water-glycol mixtures (up to 50% concentration).

Construction and application

The valve is designed for flanged mounting, which simplifies integration with existing installations. The angled passage allows for optimal adaptation to the pipeline layout. The Kvs value of 25 provides adequate flow for various applications. Thanks to the precise rotary mushroom, the valve enables smooth adjustment of the proportion of mixed streams, which translates into thermal comfort and energy efficiency. It is an ideal component for underfloor heating systems, convectors or ventilation units.

Key features and benefits

• Durability and resistance: The GG20 cast iron housing guarantees a long service life and corrosion resistance, even in harsh working conditions.
• Precise regulation: Constant percentage flow characteristic and high Kvs value (25) allow for accurate setting of the medium temperature.
• Wide temperature range: The ability to operate in a temperature range from 2°C to 130°C makes the valve universal and can be used in various applications.
• Leak tightness: Low leakage (1% of Kvs value) minimizes medium losses and ensures efficient system operation.
• Warranty: Five-year manufacturer's warranty confirms the high quality of the product and gives confidence in reliability.
• Easy installation: Flanged design simplifies integration with existing pipeline installations with a diameter of 40 mm.
• Double sealing: The use of a double O-ring seal increases tightness and minimizes the risk of leaks.

This valve finds application in residential, commercial and industrial buildings where precise control of the heating or cooling medium temperature is required. It is an essential component for installers looking for a reliable solution that provides comfort and energy efficiency.
