## Summary description

DANFOSS thermostatic radiator shut-off valve RA-N 15 (MPN 013G3903) is a replacement/service valve designed for radiators with a built-in valve body. It provides shut-off function for radiator maintenance and replacement of thermostatic heads, allowing isolation of the radiator without draining the system. Suitable for heating installations where in-place servicing and valve replacement are required.

## Long description

The DANFOSS RA-N 15 thermostatic radiator shut-off valve is a service replacement valve designed for radiators that have an integrated valve body. It allows the radiator to be isolated from the heating circuit for servicing, maintenance or replacement of the thermostatic head without draining the entire system. The valve is compatible with installations where in-place shut-off and quick radiator removal are required, supporting efficient maintenance work on central heating systems.
Advantages
The RA-N 15 provides a reliable local shut-off function, enabling radiator isolation while keeping the remainder of the heating system operational. Its design supports straightforward replacement of thermostatic heads and on-site servicing without extensive system downtime. Constructed to meet industry durability standards, the valve ensures tight closing and simple operation for maintenance personnel and installers.
Suitable for
Radiators with a built-in valve body that require a service shut-off solution
Heating systems where radiators are removed or replaced without draining the full system
Maintenance and repair tasks involving thermostatic head replacement
Installation scenarios needing quick isolation of individual radiator circuits
Key specifications
Type: Service/shut-off valve for radiator installations with built-in valve body
Connection compatibility: designed to fit radiators with integrated valve bodies (check radiator valve body type before installation)
Function: Provides isolation of radiator for maintenance and replacement of thermostatic heads
Operation: Manual shut-off to isolate the radiator from the heating circuit
Material characteristics: corrosion-resistant components suitable for central heating environments
How to use
Before installation, confirm compatibility with the radiator’s built-in valve body and ensure the heating system pressure is within safe limits. To isolate a radiator, close the RA-N 15 shut-off valve according to the installer’s instructions, then proceed with removal or servicing of the radiator or thermostatic head. After maintenance, reopen the valve, check for leaks and restore normal system operation. Follow standard safety procedures when working on pressurised heating systems and, if unsure, consult a qualified heating engineer.
Usage recommendations
Use the valve as a service isolation point only; avoid using it as a continuous flow-control device. Periodically inspect the valve for tightness and signs of corrosion, and perform leak tests after any maintenance. For complex repairs or uncertain compatibility, engage a certified installer to ensure correct fitment and safe operation.
