Adjusting actutators

[tonymorris24]

Hi all, sorry a very stupid question from a newbie. I think some of my actuators are not closing the valves fully, so there's flow even when the heating is 'off'. Is there a way of checking/adjusting these? Can I just pull them off?

Should I instead just tighten the nut at the top (the radiator-valve type one...) instead?

I don't want to break anything! Thank you.

The grey caps are your valves there flow meters

Thanks for the reply. So I need to look at the actuators to understand why there is flow when they're off - do I just pull then up/off?
