When the tank return sits under back pressure, the pilot return belongs outside. That is how this version of the 4WRKE27E500L is built: internal supply, external return, 500 l/min nominal flow and a 4...20 mA command.

A congested tank return shifts the operating point of the pilot stage and with it the characteristic curve. The 4WRKE27E500L-3X/6EG24EK31/F1D3M avoids that with a separate external pilot return and meters 500 l/min nominal flow reproducibly up to 270 bar.
Benefits
- External pilot oil return keeps the pilot stage independent of tank back pressure
- Internal pilot supply, no additional feed port required
- 500 l/min nominal flow against a 1000 l/min maximum
- 4...20 mA command, 24 VDC supply, on-board electronics
