Quite possibly but based on my set up, I don't think there is any need for a PRV in a HVLP system

I was afraid of that. Always likely to be a weak point in my plan. (my abilities not the relay itself)

I've since replaced the PRV and it's super sensitive as I only use a tiny 8mm magnet….

I bloody told you, TWICE, but no, you had to listen to someone else rather than the man who learned the hard way didn't you!?!
Well maybe that'll learn you, I don't waste my typing fingers for no reason you know…!

Andyp wrote:Rob,
When you have a moment try slowly closing the only open blast gate. I bet the the PRV will trip before the gate is fully closed.
If my maths are correct reducing 100mm tube down to the 63.5mm on the BS gives a reduction in surface area of well over half.

Thanks Andy, that explains it. I'll try your experiment and see if it works - Rob
Edit - not even halfway closed and the PRV tripped - Rob

As I have two of your old machines I would be happy to help out next time you feel the need to upgrade.
