The Siemens SXP 45.25-6.3/DC mixing set is designed for controlling mixed heating circuits in standard heating systems. The assembly includes a three-way mixing valve and an actuator with a modulating DC 0...10 V control signal, making it suitable, for example, for applications linked to weather-compensated control.

The valve is intended solely for mixing and is made of Rg5 bronze with a male thread. The set in DN25 version with a kvs value of 6.3 m3/h covers an approximate output range of 12.7 to 20.8 kW for underfloor heating and 19.1 to 31.2 kW for radiator systems. The actuator offers an actuating force of 200 N, a stroke of 5.5 mm, and a 1.5 m cable.
