To
find Outlet Pressure
(MPa/bar/psi)
at a specific
delivery
(liter/min or gpm) and operating air pressure
(MPa/bar/psi):
1. Locate
desired delivery along bottom of chart.
2.
Read vertical line up to intersection with
selected fluid outlet pressure curve (black
curves). Curve slopes from left to right.
Follow left to scale and read outlet pressure.
