## Summary description

Thermostatic radiator valve head DANFOSS C RTD 3120 (MPN 013L3120) is a replacement temperature control head for radiator valves. Designed to regulate room temperature via valve actuation, it fits compatible thermostatic valve bodies and provides manual setpoint adjustment. Suitable for residential and commercial heating systems requiring reliable room temperature control.

## Long description

Thermostatic Radiator Valve Head DANFOSS C RTD 3120 is a replacement temperature control head intended for use with compatible thermostatic valve bodies. It provides manual setpoint adjustment to regulate room temperature by driving the valve stem according to the sensed ambient temperature. The compact design is suitable for integration into residential and commercial heating systems where direct, mechanical control of radiator flow is required.
Advantages
The valve head offers precise mechanical temperature control without the need for external power, enabling continuous automatic adjustment based on room conditions. Its ergonomic rotary knob allows straightforward manual setting of the desired temperature range. The construction is durable and designed for standard radiator valve interfaces, simplifying replacement and maintenance tasks.
Suitable for
Replacement of worn or faulty radiator thermostat heads in homes
Upgrading thermostatic control on radiators in small offices and commercial premises
Zonal temperature control where individual radiators require independent regulation
Key specifications
Type: Mechanical thermostatic radiator valve head with temperature sensing element
Control: Manual rotary setpoint adjustment
Compatibility: Fits standard thermostatic valve bodies designed for Danfoss-compatible heads
Operation: Passive operation—no electrical supply required
Installation: Direct mount onto radiator valve spindle; designed for straightforward replacement
How to use
Mount the thermostatic head onto a compatible valve body following the valve manufacturer's instructions and ensure the head is secure on the valve spindle. Set the desired room temperature by turning the rotary knob to the appropriate position indicated on the scale. The head will expand or contract its sensing element in response to ambient temperature changes and modulate the valve to maintain the selected setpoint. Avoid covering the head with curtains or furniture to ensure accurate sensing.
Usage recommendations
Install the valve head on a clean valve spindle and check compatibility before replacement. For reliable performance, allow free airflow around the head and perform periodic visual inspections to ensure the mechanism operates smoothly. For systems requiring programmable or remote control, consider a compatible electronic or programmable thermostat solution instead of a mechanical head.
