Total price
On a new installation the number of ports often decides how much work the valve manifold takes. The 4WRZE25W8-325-7X/6EG24ETK31/A1D3M manages with internal pilot oil supply and internal return while delivering 325 l/min nominal flow at 350 bar.
Benefits
- Internal pilot control on feed and return, so the subplate needs no extra drillings.
- 325 l/min nominal flow against 870 l/min maximum flow.
- Analog ±10 V command at the on-board electronics with spool position feedback.
- The integrated pressure reducing valve protects the pilot stage at system pressure up to 350 bar.
- Spool symbol W8 with a defined centre condition, NBR seals for HL hydraulic fluid.
