Small axes drawing 25 l/min and a return line under counter pressure make the case for this plate. It takes pilot oil internally, drains it externally, works at up to 315 bar and follows a 4 to 20 mA command value.

The 4WRZE10E25-7X/6EG24N9EK31/F1M is the 25 l/min step with an E spool. Internal pilot oil supply saves a line while the external pilot drain keeps the control oil circuit clear of back pressure, at pressures up to 315 bar.
Advantages
- Nominal flow 25 l/min for fine, slow axis movement
- Internal pilot oil supply with external pilot oil return
- Operating pressure to 315 bar, maximum flow 170 l/min
- E spool, 3 switching positions, 4 ports, weight 8.48 kg
- Concealed auxiliary actuation, built without a pressure reducing valve
- On-board electronics, 4 to 20 mA command value, UKCA under SI2016/1091

Applications
The plate controls positioning and clamping axes with a modest oil demand, for example in inspection equipment and feeding modules. A separate pilot drain makes sense as soon as several consumers share the same return. NBR seals cover HL hydraulic fluid.
