Gurgling noise through fitted TRV's

[Beckmeister General]

I've had TRV's fitted (B&Q ones) and now on a few of radiators I'm getting gurgling noises. Is this normal when water is passing through the valves?

how many rads have you got and how many are fitted with trv's
were the rads bled and balanced??

Thanks for the reply
I've 13 rads in total.
1 rad has no TRV (hall where the thermostat is)
I've bled all the rads 3 - 4 times and I do get a small amount of air trapped in 2 of the rads.
One of the radiators that gurgles has the air trapped in it, the other that gurgles has no air trapped.
The rads have not been properly balanced just adjusted so all the rads were hot.

Hope that I 've explained myself

it is a sealed system or open vented
the rad without the trv are the wv & lsv open fully
do you have an ab fitted
