A loaded tank return is the most common reason for drifting switching times. This version takes pilot oil internally and drains it through a port of its own, at 500 l/min nominal flow, 270 bar and a 4...20 mA setpoint.

When many actuators share one return line, pressure builds there and the pilot chambers feel it. The 4WRTE27V1-500L-4X/6EG24EK31/F1M avoids that with a separate pilot drain while still supplying itself internally, at 500 l/min nominal flow and up to 270 bar.
Benefits
- Internal pilot oil supply with external pilot oil return, only one extra line.
- 500 l/min nominal flow in size 27, maximum flow 1000 l/min.
- 4...20 mA command value on 24 VDC, on-board electronics with spool position feedback.
- Spool symbol V1, 3 switching positions, operating pressure up to 270 bar.
- NBR seals, ISO 4401-08-07-0-05 interface, 19.38 kg.

Applications
The variant is chosen when switching times in an existing system drift and the return line is confirmed as the cause. It works without a pilot pump and needs only one additional line to tank. Presses and multi-axis lifting gear are typical.
