Simon, there isn't one.
Thanks for all the replies so far.
DP, there are at least 3 rads with no TRV. I hope a shoe type valve solves the bangin' problem.............
I know have the valve in my posession and it does look like a nice piece of engineering. I need to find time to do the job.
I'll report back on any results.
Will I get away with 'bunging' the feeed and expansion to let it hange for the valve do you think?
