Anyone controlling a large press axis while keeping the pilot circuit separate gets 325 l/min nominal flow in size 25 here. The 4WRZ25W8-325-7X/6EG24N9K4/D3V takes pilot oil externally and drains it externally. Peaks up to 870 l/min are possible in the main channel.

A pilot-operated axis runs only as cleanly as its pilot oil circuit. The 4WRZ25W8-325-7X/6EG24N9K4/D3V draws pilot oil from an external source and returns it through a dedicated line, while the main channel carries 325 l/min nominal flow.
Advantages
- 325 l/min nominal flow, peaks to 870 l/min in the main channel of size 25.
- Pilot oil supplied and drained externally, with a pressure reducing stage in the pilot circuit.
- Spool symbol W8 with three switching positions, plus concealed auxiliary actuation for setup work.
- ISO 4401-08-08-0-05 pattern, size 25, rated up to 350 bar operating pressure.
- Connector, 3-pole (2 + PE) for the electrical link, 24 VDC supply.
- 20.42 kg mass, FKM seals, HL grade fluid.
