Pressure drop diagram

Pressure vs current

Note: Supplying current to the coil from 0 to I max (see diagram), a proportional pressure variation is obtained on port P. For the controller see table D170 Recommended tightening torque: 25Nm Recommended filtration: 25 ÷ 50 µ Oil temperature: -30 ÷ + 80 °C
