RadValve Spindle Stuck

This is a lockshield. It has (obviously) not been turned for years. It is only open a fraction. When I tried to open it, it wouldn't move. When I tried to close it (thinking to loosen it) the spindle assembly from the lower brass nut started to come out, it must have a LH thread.

What would be the correct thing to do?

Try holding the main hex with another spanner otherwise replace the valve (it's rubbish quality anyway..no seperate gland nut).

Some radiator valves are well known for siezing..the worst is the Myson Matchmate series popular with microbore new build. The thread helix angle is way too high giving only a couple of turns (open to closed)...they always sieze and the spindles are often found sheared off. doesn't stop idiots fitting them though.

I tried to force one a few years ago and it broke off spraying the ceiling!

Well the gaffer did tell me to open it!

At least this one has the drain point built in for the 'Emergency' Drain down!
