Proportional Directional Valve 4WRZ25W9-325-7X/6EG24N9ETK4/D3M - Bosch Rexroth R901045065

Very large cylinder areas call for more oil per second than 220 l/min nominal flow provides. The 4WRZ25W9-325-7X/6EG24N9ETK4/D3M works at 325 l/min in the same size 25 and feeds its pilot stage entirely internally.

Benefits

• Connection diagram ISO 4401-08-08-0-05 in size 25, four ports.
• Nominal flow 325 l/min, maximum flow 870 l/min.
• Pilot stage with pressure reducing valve, internal pilot oil supply and internal return.
• Three switching positions with spool symbol W9, operating pressure to 350 bar.
• 20.6 kg, concealed auxiliary actuation, 24 V DC supply.

Applications

Typical applications are forming machines and lifting gear with large cylinder cross sections. Subplate mounting to ISO 4401-08-08-0-05 fixes the valve interface, so the valve can be exchanged against other versions of the same size.
