I know this is basic knowledge but my trvs are confusing me
Started searching as I didn't want to appear to be an idiot but this seems to be impossible
Found this on the Drayton faq
What range of TRV bodies are Bi- directional?
The 15, 10 or 8mm angled body is bi directional as denoted by the double headed arrow on the valve body. ALL other bodies are flow directional as indicated by the single headed arrow head on the valve body.
All makes sense to me so went and had a look at mine and whilst they appear to bidirectional, should I have a double headed arrow or do two arrows in opposite directions mean the same thing ?
In case I've managed to confuse you as well, here's a link to a rubbish picture taken on my phone - if you zoom in, you should able to see the arrows I'm talking about

I'll just sit back now and wait for the name calling to end
