Not every axis that needs unloading needs the 325 step. The 4WRZE25E1-220-7X/6EG24ETK31/A1D3M offers spool symbol E1 at 220 l/min nominal flow and manages without external pilot oil lines.
Benefits
- 220 l/min nominal flow matches cylinders of medium bore without wasting valve capacity.
- Spool symbol E1 for axes that should be unloaded in centre position.
- Internal pilot oil supply and internal pilot oil return, easy to mount and low on leak points.
- The integrated pressure reducing valve keeps pilot pressure stable at system pressure up to 350 bar.
- Analog ±10 V command, maximum flow 870 l/min, mounting pattern ISO 4401-08-08-0-05.
