Wait a second here.....i'm not so sure I dont need 30 lbs of force if
i want to regulate 30 psi, for instance...the fluid being regulated
has to "lift up" the ball in the orifice, and if there is 30 lbs on
that ball you get 30 psi, yes?

30 psi does not mean 30 pounds of force, it means
30 pounds per square inch. What's the cross sectional
area of the ball? How about the orifice in which it
sits?
