This build combines a fully external pilot circuit with a ±10 V voltage command value and the V1 spool. It meters 350 l/min nominal flow at 350 bar and reports spool position back internally, so the same position is reached again on every stroke.

When the controller supplies a voltage signal and the pilot circuit is already built separately, this combination of ±10 V command value and external pilot routing fits. Nominal flow 350 l/min, operating pressure 350 bar.
Benefits
- Command value ±10 V without a signal converter, V1 spool
- External pilot oil supply and external return for a self-contained pilot circuit
- Nominal flow 350 l/min, up to 870 l/min through the valve
- Internal spool position feedback rather than open-loop control
- Operating pressure 350 bar, three switching positions, four ports
- Weight 17.9 kg, port pattern ISO 4401-08-08-0-05

Application
The variant controls axes in roll gap adjustment, servo presses and test rigs with a central pilot supply. Because the pilot circuit stays separate, its pressure can be set independently. HL is the intended hydraulic fluid, sealed with NBR at 24 VDC.
