Images are for illustration purposes only and may differ from the actual product. Some images have been generated or edited, in whole or in part, using artificial intelligence systems. The technical specifications in the product description are authoritative.
Controllers with a voltage output find their match here: ±10 V DC command value, 325 l/min nominal flow and size 25. Pilot oil is supplied externally and returned externally, and operating pressure reaches 350 bar.

Total price
Many axis control cards issue their command as a voltage. The 4WRZE25W9-325-7X/6EG24N9K31/A1D3M suits that directly, processes ±10 V DC and provides 325 l/min nominal flow in size 25 at operating pressure up to 350 bar.
Benefits
- Command value ±10 V DC, directly compatible with common axis control cards and analogue outputs.
- 325 l/min nominal flow, with 870 l/min as the maximum flow of the range.
- External pilot oil supply with external return, plus a pressure reducing valve in the pilot path.
- Symbol W9 in three switching positions with concealed auxiliary actuation.
- Weight 20.76 kg, NBR seals, mounting pattern ISO 4401-08-08-0-05.

Applications
The valve drives main cylinders in presses and test rigs whose control runs on an analogue voltage interface. Because pilot pressure is built up by a dedicated reducing valve, response stays comparable across the pressure range. Swapping to the identical valve with a current interface needs no change to the hydraulics.
