Total price
Some plants offer neither a stable pump pressure nor a calm return line. The 4WRTE25E220L-4X/6EG24ETK31/A1V therefore draws pilot oil from its own source and drains it separately, at 220 l/min nominal flow and 350 bar operating pressure.
Benefits
- Pilot oil supply and drain are routed externally, so the pilot stage works independently of the main circuit.
- 220 l/min nominal flow and up to 870 l/min maximum flow.
- A ±10 V command value at the on-board electronics, 24 VDC supply.
- Spool symbol E, three switching positions, four ports, ISO 4401-08-08-0-05 mounting pattern.
- 350 bar operating pressure, FKM seals, 18 kg valve mass.
