Total price
A pilot operated valve needs pilot pressure to switch. If that pressure comes from a separate circuit, as here, the axis can be positioned even with the main pump unloaded, for example during set-up. The 4WRTE25W6-350L-4X works at 350 l/min nominal flow and up to 870 l/min.
Benefits
- External pilot oil supply and external pilot oil return, independent of working pressure
- 350 l/min nominal flow, 870 l/min maximum flow
- Spool symbol W6, 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 operating pressure, HL hydraulic fluid

Applications
Used on plants with set-up and jog modes where movement is still needed while the main pump is off. A small pilot power unit then supplies every valve on the machine. At 350 l/min nominal flow there is still enough flow for production duty on large cylinders.
