Advantages
- Internal pilot oil supply and internal return, no extra lines on the manifold.
- Nominal flow of 25 l/min for fine feed movements at pressures up to 350 bar.
- Current command 4...20 mA, suitable for longer cable runs to the controller.
- Spool symbol W8, connection diagram ISO 4401-05-05-0-05, subplate mounting.
- Internal spool position feedback for repeatable characteristic curves.
- Weight of 9.44 kg, 24 VDC supply voltage, HL hydraulic fluid.
