Thanks
I need to know how many psi to set my compressor at to keep valve closed when
removing spring.

Re: removing valve spring,How much psi to keep val

I would guess the more the merrier! Unless or course you have some type of industrial strength compressor.
Did you see this article?

When I've done it in the past, I just left my regulator at 90psi. I'm sure you could do it with a lot less, but I don't know what the minimum would be. Ten psi would probably work, but higher pressures don't seem to hurt anything.
