you frustrated because your machine functions aren't consistent and repeatable
due to fluctuations in plant air pressure?
Because the areas of the end seals and the poppet
seals on a MAC valve are engineered to be equal, the inlet pressure
provides an equal force to each. Thus, there is no net force on the poppet due
to the inlet air pressure. Therefore, changing inlet pressure has no effect on
shifting forces, and will not affect the timing characteristics of the valve.
