Amazing what some people believe!
I would never advise anyone NOT to use the traditional lockshield method of balancing rads in a normal installation.
Yes, the well designed TRV4s do include this feature. But in my view lockshields are easier to adjust for balancing.
I suppose one reason to use the TRV4 would be for the Polish builder tenants who like to fiddle. But not for normal tenants or owner occupiers.
