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.

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