Check the poppet seal itself as well. Make sure it is clean and not damaged. If it still leaks, I would replace it.
I would also make sure the air flow through the seal screw and poppet is not plugged up with dirt.
As for lube, I would be a bit more generous with it in the valve (not in the pilot housing). I make sure the poppet and spring is lubed.
Also check or replace the valve body o-rings.
Your saying the poppet seal can cause low velocity/this issue?
The hole is clean and the seal is undamaged.The screw was given a dab of loctite when I first cleaned it .
