Apply pressure at the valve inlet and at 29-30 psi it should pop open.
You can also change the setup for R-134a by loosening the screw in the outlet (I think it's the outlet) by a tiny bit so that the valve opens at 27-28 psi.

Default POA Testing

I have this one, but somewhere I have a better one. I don't know how well you will be able to see it but if you need a better picture I can try to email it to you.
