Don't use the valve in the original post!!!!!!!!
Needless to say when I tested the valve in the original post it was a high preasure valve. Only open the tinest bit the stove was like the Space Shuttle ignition!! I thought the stove, me and the boat were going into orbit!
I took the old regulator
and the new valve into the Gas (gaz) shop today at our newest port of call larger than a village and we did swapsies onto a different valve and a new regulator.
Now the gas flow isn't very strong at all!
That I need to sus out.
The new reg says 0.3-16 Bar LPG

(Yes I know the hose is going on the full way as soon as I boil some water!)
