Lever ball valves - is flow direction important?

[Nick]

Have fitted quite a few of these

always have been able to arrange them so that the handle will gravity to 'off' . The valves have a flow direction arrow cast into the body and the handle is not reversible. I now have to fit one where the flow will go against the directional arrow or the handle will drop to 'on'. From what I can see this will not matter but opinions or experience would be V much appreciated.

Many thanks,

Nick.

I've been using these:

of the slotted isolators, for some time. They are stiff enough not to turn back on their own - and usually only a fraction of the price Screwfix are asking here!

Not sure why you would need a big lever for 15mm?
