Proportional Directional Valve 4WRZE25W9-325-7X/6EG24N9K31/A1D3M - Bosch Rexroth R901084809

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.
