To find Fluid Outlet Pressure (psi/MPa/bar) at a spe-
cific fluid flow (lpm/gpm) and operating hydraulic pres-
sure (psi/MPa/bar):
1. Locate desired flow along bottom of chart.
2. Follow vertical line up to intersection with selected
fluid outlet pressure curve (black). Follow left to
scale to read fluid outlet pressure.
