Total price
Large lifting cylinders often have to stand depressurised between strokes without sinking. The 4WRZE25E1-325-7X/6EG24K31/A1D3M serves that case with spool symbol E1 and provides 325 l/min nominal flow at 350 bar for it.
Benefits
- Spool symbol E1 combined with 325 l/min nominal flow covers large axes that need unloading.
- External pilot oil supply and external pilot oil return for plants with a separated pilot circuit.
- Analog ±10 V command taken straight from the analog output of the controller.
- The integrated pressure reducing valve holds pilot pressure steady regardless of working pressure.
- Maximum flow 870 l/min, valve mass 20.58 kg, mounting pattern ISO 4401-08-08-0-05.
