How to remove the white button on the radiator to adjust the temperature?

1. First, if there is a coupling next to the adjusting cover of the temperature control valve, you can remove the coupling with a wrench or pipe wrench.

2. Secondly, remove the adjusting cover. For the temperature control valve, the temperature control valve is directly connected with the pipeline, and the pipe at the threaded joint of the pipeline needs to be cut before the temperature control valve can be removed.

3. After the valve is finally replaced, another PPR threaded joint can be welded and disassembled.
