Where several valves discharge into the same tank line, back pressure disturbs the pilot stage. The 4WRZE10W6-50 therefore drains its pilot oil through a dedicated port and meters 50 l/min under a ±10 V command at up to 315 bar.

Total price
This size 10 valve controls an actuator at 50 l/min nominal flow. Pilot oil is taken internally but returned externally, which decouples the pilot stage from the counter pressure of a shared return line.
Benefits
- External pilot oil return protects the pilot stage against counter pressure in a shared return line
- Internal pilot oil supply without an additional pressure line
- 50 l/min nominal flow, 170 l/min maximum flow, 315 bar operating pressure
- Spool symbol W6, 3 switching positions across 4 ports
- On-board electronics with ±10 V command, 7-pole connector (6 + PE) to EN 175201-804
