Which Tial spring do I have?
 

Hey guy's, I just bought a used Tial 46mm WG. I think it has a 10psi spring but the color isn't on their chart. It's silver. They show red,green, blue and yellow??

I'm going to put some air pressure to it tonight to see when it opens but I don't know how accurate that will be without the exh. pressure pushing too.

Thanks, Scott
