PVHC current response and hysteresis @ 25 bar Pp, 21 ctS, 25 °C. The ideal curve is determined by the
main spool neutral spring. The PVHC has high hysteresis. The hysteresis is affected by viscosity, friction,
flow forces, dither frequency and modulation frequency. The spool position will shift when conditions are
changed e.g. temperature change.
