A high-volume axis can only be controlled if the directional valve passes the oil flow without throttling it. This pilot-operated size 25 build carries 400 l/min nominal flow, takes a maximum operating pressure of 350 bar and uses spool symbol E.
Benefits
- 400 l/min nominal flow with a maximum flow of 1250 l/min.
- Maximum operating pressure 350 bar at a valve weight of 18.52 kg.
- Internal pilot oil supply and internal pilot oil return, so no separate pilot port has to be plumbed.
- Spool symbol E with 3 switching positions and 4 ports, mounting pattern ISO 4401-08-08-0-05.
- On-board electronics with an analog command value of ±10 V on 24 VDC, CE conformity.

Applications
The valve controls large cylinders in presses, forging lines and injection moulding machines as well as hydraulic motors with high displacement. 400 l/min nominal flow and a maximum flow of 1250 l/min cover fast rapid strokes. Internal piloting keeps the piping limited to the four working ports. Subplate mounting follows the ISO 4401-08-08-0-05 pattern.
