If so please could you tell me if this is a normally open valve? A member previously supplied me with this diagram, but the diagram on the valve picture looks slightly different, so just want to make sure. I am wwanting to use it as a fill/pilot valve on a qev gun

Thanks Ian

To me, it looks more like your "normally closed, spring offset solenoid operated 3 way" diagram reversed left to right. That said, the photo is small and blurry and my eyes are old and weak.

if you haven't bought one, you should keep looking for normally open valve. Sometimes you can modify them to NC or NO, but not always..
