With 85 l/min nominal flow the 4WRZE10W8-85-7X/6EG24EK31/A1D3M covers the upper flow range of size 10 without calling for a dedicated pilot pressure line: supply is internal from port P, draining external through Y. The spool of symbol W8 follows the +/-10 V command value up to 315 bar operating pressure.
Benefits
- 85 l/min nominal flow, maximum flow 170 l/min at 315 bar operating pressure.
- Internal pilot supply saves the X line, external draining keeps the pilot stage free of return back pressure.
- Command value +/-10 V, on-board electronics with internal position feedback, 24 VDC.
- Spool symbol W8, 3 switching positions on 4 ports.
- Subplate mounting to ISO 4401-05-05-0-05, weight 8.45 kg.
- Built-in pressure reducing valve, NBR seals, UKCA conformity.

Application
The high nominal flow of this size matches fast infeed movements on forming and plastics machinery. Because pilot oil is drawn internally, port P must be under permanent pressure. External draining through Y pays off in particular when several valves share the same return line.
