Danfoss RAVK 25-65 degree thermostatic element, for temperature control of small hot water spokes

The Danfoss RAVK thermostat actuator is a heating control component designed for precise temperature regulation in hydronic heating systems. This actuator model 013U8063 operates with thermostatic control to automatically open and close radiator valves based on room temperature settings. This ensures a consistent thermal comfort level and optimizes energy efficiency. The actuator is made from durable materials and features a compact design with a height of approximately 55 mm and a standard M30x1.5 connection thread, ensuring compatibility with most radiator valves. It operates within a temperature range of 5 °C to 28 °C with an accuracy of ±1 °C and responds to changes in ambient temperature to maintain the desired comfort levels. The device does not require an external power source and works solely on the principle of thermal expansion. Additionally, it has a manual override function for temporary adjustments. Suitable for water-based heating systems with a maximum operating pressure of 10 bar and a fluid temperature of up to 120 °C, this thermostat actuator is designed for reliable long-term performance in residential and commercial applications. Installation is straightforward with standard tools, and the white housing blends discreetly into most interior designs. The product represents Danfoss's commitment to energy-efficient heating solutions through precise temperature control technology.
