If this was a lock shield shouldn’t turning the plastic top do nothing? Both ends will turn the radiator off if I turn them.
Sorry, completely new to this and have gotten all my knowledge from a google how to guid for balance radiators :mrgreen:
Hi,
I’m a little confused with my radiator set up. I have one radiator that doesn’t get as hot as others. I was looking into balancing the system but my radiators don’t seem to have a lock shield valve. I seem to have both a manual and a TRV? I’ve attached 2 photos of the same radiator
Is this...
