Proportional Directional Valve 4WRZE25W9-325-7X/6EG24N9ETK31/A1D3V - Bosch Rexroth R901272918

Anyone needing more than 220 l/min in size 25 reaches for the 325 rating. The 4WRZE25W9-325-7X/6EG24N9ETK31/A1D3V offers it and at the same time avoids external pilot lines, because pilot supply as well as return run internally.

Benefits

• 325 l/min nominal flow, up to 870 l/min maximum flow.
• Internal pilot oil supply plus internal return, no additional lines.
• Command value ±10 V on the on-board electronics, 24 V DC supply.
• Symbol W9 with a pressure reducing valve in the pilot stage, 350 bar operating pressure.
• FKM seals, connection diagram ISO 4401-08-08-0-05, concealed manual override.
• 20.66 kg, UKCA evidence SI2016/1091 for electromagnetic compatibility.

Applications

The valve fits tightly built manifolds where system pressure is permanently available. At 325 l/min nominal flow it serves cylinders for which the 220 rating would be too slow, without moving up to the next frame size.
