Proportional Directional Valve 4WRZE25W6-325-7X/6EG24N9TK31/F1D3M - Bosch Rexroth R901225433

When pilot oil arrives from the outside at a level above what the pilot stage needs, a stage in between is required inside the valve. This version has one built in, is fed through X, drained internally and controls 325 l/min with spool symbol W6.

Benefits

• Pressure reducing valve in the pilot line makes pilot pressure independent of the level of the external supply.
• External supply X with internal drain keeps the number of control lines at one.
• Nominal flow 325 l/min, peak 870 l/min, operating pressure up to 350 bar.
• Spool symbol W6 with three switching positions and concealed auxiliary actuation.
• Current command 4...20 mA, on-board electronics on 24 VDC, mass 20.66 kg.
