When a switching valve is replaced by stepless control, the analogue output of the controller usually stays as it is. The 4WRTE10W8-50L-4X/6EG24EK31/A1M accepts the plus/minus 10 V command and turns it into a 50 l/min nominal flow.

Total price
Converting a clamping or feed axis from switched to stepless actuation should not force a change of the existing analogue output. The 4WRTE10W8-50L-4X/6EG24EK31/A1M takes plus/minus 10 V and releases up to 50 l/min nominal flow from it.
Advantages
- Plus/minus 10 V command, the existing analogue output of the controller stays in use.
- Nominal flow of 50 l/min, operating pressure up to 350 bar.
- Internal pilot oil supply from P with external return through Y.
- Spool symbol W8, three switching positions, four ports, ISO 4401-05-05-0-05.
- On-board electronics with internal spool position feedback.
- Weight of 9.5 kg, NBR seals, 24 VDC supply voltage.
