Metering 220 l/min into a press cylinder and stopping it where the controller asks takes more than a switching valve. The 4WRZE25W8-220 is a pilot operated proportional directional valve in size 25, rated to 350 bar, carrying its amplifier on the body.
Benefits
- Nominal flow 220 l/min with headroom up to 870 l/min for peak strokes
- Operating pressure up to 350 bar across all 4 ports
- Spool Symbol W8 with spool design, 3 switching positions
- External pilot oil supply and external pilot oil return, no pressure reducing valve in the pilot stage
- On-board electronics with internal spool position feedback hold the command value without an external controller

Applications
Typical places are presses, injection moulding machines and hydraulic test rigs where a cylinder travels at up to 870 l/min before it has to stop on a defined position. The ISO 4401-08-08-0-05 interface allows a swap against an existing size 25 valve without touching the subplate. At 11 kg of dead weight, plan a sufficiently stiff mounting.
