This version needs one pilot line less than the fully external variant. Pilot oil comes from outside but returns to tank internally. The 4WRTE25E220L-4X controls 220 l/min nominal flow at 350 bar with a ±10 V command value.

Between a fully internal and a fully external pilot circuit sits the mixed variant. External supply secures pilot pressure while the internal return saves a line. This 4WRTE25E220L-4X is built that way, with spool symbol E and 220 l/min nominal flow.
Benefits
- External pilot supply for reliable pilot pressure, internal return saves one line
- 220 l/min nominal flow, 870 l/min maximum flow
- Spool symbol E, three switching positions, four ports
- Analog ±10 V command value, on-board electronics, 24 VDC supply
- ISO 4401-08-08-0-05 interface, 350 bar, NBR seals, HL hydraulic fluid
