The actual valve flow is dependent on the spool position and the pressure drop across the spool lands.
At 100% command signal (i.e. +10 VDC = 100% valve opening), the valve flow at rated pressure drop ∆pN = 35 bar (500 psi) per
metering land is the rated flow QN. For other than rated pressure drop, the valve flow changes at constant command signal
according to the square root function for sharp edged orifices.
