Replacing a failed valve is mostly about matching signal type and oil routing. The 4WRZE10W9-85-7X with a plus or minus 10 V command, internal pilot supply and external return hits the most common combination while metering 85 l/min nominal flow.
Benefits
- A plus or minus 10 V command works straight off the analogue output of usual controller cards.
- Internal pilot oil take-off saves one feed line, the external return keeps the pilot circuit relieved.
- 85 l/min nominal flow, operating pressure to 315 bar, spool symbol W9 with three switching positions.
- On-board electronics inside the valve, powered by 24 VDC at a 7-pole connector (6 + PE) to EN 175201-804.
- Mounting pattern ISO 4401-05-05-0-05, weight 8.47 kg, NBR seals.

Applications
The version runs feed and press axes, plastics machinery and lifting gear. Because the electronics sit inside the valve, a separate amplifier card in the cabinet is no longer required. Concealed auxiliary actuation allows emergency moves without control voltage.
