Advantages and features of Danfoss temperature control valves

‌High-precision temperature control and intelligent adjustment‌

Adopting CA-level certified design, the temperature control accuracy is ±1℃, supporting 1℃ scale precise adjustment, significantly improving the room temperature stability;

Built-in temperature sensor and PI/PID algorithm can sense the ambient temperature changes in real time and automatically adjust the flow, reducing the need for manual intervention;

Support outdoor temperature compensation function, automatically adjust the water supply temperature according to the temperature difference between day and night, and optimize energy efficiency.

‌Significant energy saving effect‌

Compared with traditional manual valves, energy consumption is reduced by about 36%, and winter gas costs can be saved by 500-700 yuan/household (based on 2000-3000 yuan);

"Free heat" such as solar energy and electrical waste heat can be used, and the comprehensive energy saving rate can be increased by more than 20%.

‌Easy to install and maintain‌

Unique RA-Click technology, quick installation without tools, and calibration and maintenance-free after installation;

Modular structure design, the valve body and controller can be separated and replaced, reducing maintenance costs.

‌High safety and reliability‌

The dual-core heating cable design has passed IEC-800 certification, with extremely low electromagnetic interference and far greater safety than single-core cables;

When water or power is cut off, the valve can be automatically closed or kept in place to prevent scalding and system out-of-control risks;

The valve body and fluororubber seals made of high-pressure cast steel can withstand high temperature, high pressure and corrosive water.

‌Long life and compatibility‌

The heating cable has a 10-year warranty and a service life of up to 50 years. The thermostat supports frequent switching (15-20 seconds/time);

It is suitable for single-tube, double-tube and vertical series systems, and provides hard-sealed connections to prevent leakage.

Precautions for use

‌Installation specifications‌

It needs to be installed vertically at the water inlet of the radiator. The direction of the valve body arrow is consistent with the water flow. Inclined installation may cause adjustment failure;

Flush the pipes thoroughly before installation to prevent welding slag from clogging the valve core. The newly installed system needs to run for 72 hours before debugging.

‌System Adaptation Requirements‌

When the water contains particulate matter, a filter needs to be installed (the recommended accuracy is ≤40μm). It is recommended to pickle the pipes regularly in hard water areas;

The single-pipe system needs to be equipped with a three-way temperature control valve to avoid affecting the temperature control effect due to insufficient diversion coefficient.

‌Operation and Debugging‌

When setting the temperature for the first time, turn the knob to the middle scale, wait for 1-2 hours to stabilize, and then fine-tune (each adjustment is ≤0.5 scale);

After the heating season ends, the valve needs to be adjusted to the highest gear and run for 10 minutes to prevent the valve core from getting stuck.

‌Maintenance‌

Check the sealing every quarter: after pressurizing to 6bar, use soapy water to detect the interface, and replace the sealing ring if it leaks;

Before long-term deactivation, drain the water in the pipe and apply silicone grease to the valve stem to prevent rust.

‌Special Environment Management‌

The solenoid valve needs to be kept away from strong magnetic field equipment (such as transformers), and shielded cables are recommended for signal lines;

For high-temperature steam environments (＞100℃), stainless steel valve body models should be used to avoid deformation of plastic components.

By properly applying the above characteristics and operating in accordance with standard procedures, Danfoss temperature control valves can achieve efficient energy saving and precise temperature control in residential, laboratory and industrial scenarios, while ensuring safe and stable operation of the system.
