On board and in the shipyard what counts is that an axis keeps its speed even under changing load. This size 32 valve uses internal piston position feedback for that, handles ±10 V and meters 520 l/min at 350 bar. Its pilot circuit is fed externally.

Changing loads pull the speed of a simple valve away as soon as load pressure rises. The 4WRZE32E520-7X/6EG24N9K31/A1M holds the command value through its piston position feedback and meters 520 l/min at 350 bar from a ±10 V command.
Benefits
- Piston position feedback inside the valve holds the relation between command and flow under changing load pressure.
- 520 l/min at 350 bar in size 32, body limit 1600 l/min.
- External pilot oil supply and external drain keep the axis independent of pressure in the main circuit.
- E spool, four ports, three switching positions, ISO 4401-10-09-0-05 interface.
- 43.48 kg, ±10 V command on 24 V DC, NBR seals, HL hydraulic fluid.
