Thanks. I can appreciate the large diameter pipe making the difference but doesn't the 1/4 of the valve restrict it back again?

Yes.
8mm o.d. pipe should be fine.
Your aware that 1/4 ... when applied to pipe fittings ... has got nothing to do with the actual thread measurement... it is taken from the nominal bore of the pipe.
ok, I`d read something about pipe threads (I think it might have been on your site!) but didn`t associate it with the valve sizes. Should be ok what I`ve bought then. Thanks
Google your valve part number ... you should be able to find it's flow in l/min or Flow coefficient... Cv Kv.
EDIT...The 1/8 1/4 1/2 etc when applied to your valve is the BSP thread size in the port...it could also be American..NPT
