Anyone running several controlled axes off one shared pilot oil supply wants the same pilot logic on all of them. The 4WRZE25W8-220-7X/6EG24K31/A1D3M fits that scheme with external pilot oil supply, external return and 220 l/min nominal flow.
Benefits
- 220 l/min nominal flow covers feed and pressing axes of medium size.
- Fully external pilot control gives equal response times across all valves on a manifold.
- Analog ±10 V command at the on-board electronics, with no amplifier card in the cabinet.
- The integrated pressure reducing valve holds pilot pressure steady at system pressure up to 350 bar.
- Maximum flow 870 l/min, mounting pattern ISO 4401-08-08-0-05, NBR seals.
