When the switching times of a 500 l/min valve must stay independent of the cycle, the pilot stage is fed from outside. This version with spool symbol E1 does that through X and Y and takes a ±10 V command.

The 4WRKE27E1-500L-3X/6EG24K31/A1D3M separates the pilot stage completely from the main circuit. Pilot oil arrives through X from a dedicated source and leaves through Y, so neither a collapse nor back pressure affects spool travel. Spool symbol E1 works linearly and passes 500 l/min nominal flow, 1000 l/min at peak.
Benefits
- Fully external pilot routing through X and Y, independent of the main circuit.
- Spool symbol E1 with a linear curve and 500 l/min nominal flow.
- Maximum flow 1000 l/min at operating pressures to 270 bar.
- ±10 V command at the on-board electronics with internal closed loop spool control.
- NBR seals, 19.36 kg, mounting pattern ISO 4401-08-08-0-05.
