Quickie on changing rad with thermo valve

Hello everyone,

I have a slow leak on one end of a rad (on a sealed heating system) and plan on closing the rad valves each end and wrapping PTFE tape around thread to stop leak.

On the opposite end to the leaking valve is a thermostatic valve. If I set this to zero will that close off the water to allow me to remove rad?

Most unlikely - use the decorators cap that holds the pin right down.
The body of the TRV just unscrews from the valve.
