I nearly avoided completely unexpected disaster when opening the lockshield valve fully open as somehow the safety ring (as shown in pictures) came off due to which the small screw inside lockshield few away and water fountain came out. I haven't applied too much pressure to open the lockshield fully and just used standard L N key. TRV was fully open to number 5.
I managed to close the lockshield again after burning few fingers with hot water fountain and soaking carpet.
I tried same force on other similar lockshield in spare (from old radiator) and it was not possible to see safety brass ring coming off irrespective how tightly I try to open the valve with L N key.
Now, do you recommend replacing the lockshield (which means draining whole system, loosing £40 worth inhibitor which is added yesterday and paying plumber again for the same job which he did yesterday whilst replacing one of the other (working) lockshield with TRV.
OR
Just push the ring inside (which I did) but it is now very easy to take it out with little finger. I hammered it in gently as do not want to break copper joints which will be massive disaster in itself. I doubt if I go with second option and someone else try to open the lockshield for balancing etc, it may run into same issue.
Googling doesn't suggest any relevant article on similar issue.. looks like quite rare as I do not expect stop cocks / lockshields etc to fail like this.. can expect bit of a leak etc.
