A dedicated pilot circuit for the whole manifold simplifies the design considerably. The 4WRZE10W6-50 fits into that concept: pilot oil arrives and leaves externally while 50 l/min nominal flow is metered under a ±10 V command.

This size 10 valve is the version with a fully external pilot oil circuit. Pilot inlet and outlet sit outside the main circuit, which gives the most uniform design in manifold solutions with a central pilot pump. Nominal flow is 50 l/min.
Benefits
- External pilot inlet and outlet suit manifolds with a central pilot pump
- 50 l/min nominal flow at 170 l/min maximum flow and 315 bar
- ±10 V command straight into the on-board electronics, without an intermediate amplifier
- Spool symbol W6, 3 switching positions, 4 ports, connection diagram ISO 4401-05-05-0-05
- FKM seals, HL hydraulic fluid, weight 8.48 kg
