Could you have plumbed the leveling valve backwards? meaning down is up and up is down? Easy way to check that is to remove the leveling rod and move the arm the opposite way.

I'm sure it's correct the 2 ports are supply and suspension. It's the correct valve and it's quality it's a new way valve.
