This E1 version of size 27 takes its pilot oil internally and returns it externally through Y. That saves the X line and still keeps the pilot stage clear of the tank line. Nominal flow is 500 l/min at 270 bar with a ±10 V command.

On the 4WRKE27E1-500L-3X/6EG24EK31/A1D3M the piping effort stays low without the pilot stage suffering from the return level of the main circuit. Spool symbol E1 releases 500 l/min nominal flow on a linear curve, 1000 l/min is possible for short periods, and the internal position transducer corrects the spool.
Benefits
- Internal pilot supply with external return, only one extra line at the block.
- Spool symbol E1 with a linear curve, 500 l/min nominal flow, up to 1000 l/min.
- Operating pressure to 270 bar in size 27 with four ports.
- Closed loop spool position control through the internal transducer, ±10 V command.
- NBR seals, 19.46 kg, mounting pattern ISO 4401-08-08-0-05.
