A pressure dip in the main circuit must not block reversal. The H-4WEH25HE6X/6EG24NSK4/B08 takes pilot oil externally and returns it externally, switches to spool symbol E and handles up to 700 l/min at 350 bar.

Total price
If main pressure dips briefly during reversal, an internally piloted valve loses its pilot pressure. The H-4WEH25HE6X/6EG24NSK4/B08 therefore takes its pilot oil from outside and returns it externally as well. In size 25 it switches up to 700 l/min at 350 bar.
Benefits
- External pilot supply and external return for reliable reversal.
- Flow up to 700 l/min, operating pressure to 350 bar.
- Spool symbol E with three switching positions in size 25.
- Solenoid voltage 24 V DC, connection diagram ISO 4401-08-08-0-05.
- 18.31 kg in weight, NBR seals, four ports.

Applications
It is used in circuits with accumulator operation or strongly changing load, for instance on presses and lifting equipment. A pilot source of its own keeps pilot pressure steady, whatever the main circuit is doing at that moment.
