Proportional Directional Valve 4WRZ25W9-325-7X/6EG24N9EK4/V - Bosch Rexroth R900975730

If the main circuit supplies pilot pressure anyway, internal supply saves a dedicated line. The 4WRZ25W9-325-7X/6EG24N9EK4/V works with internal pilot oil supply and external pilot oil return and meters 325 l/min nominal flow.

Benefits

• Internal pilot oil supply, external pilot oil return, without pressure reducing valve
• Nominal flow 325 l/min, maximum flow 870 l/min
• Spool symbol W9, three switching positions across four ports
• Pilot-operated spool valve with concealed auxiliary actuation
• Maximum operating pressure 350 bar, FKM seals, weight 20.26 kg

Applications

Meant for large cylinder axes on presses, test rigs and forming plants with a shared pressure supply. The external return keeps tank pressure away from the pilot stage. Control runs through external electronics, 24 VDC supply.
