Proportional Directional Valve 4WRZE25W9-325-7X/6EG24N9ETK31/A1D3M - Bosch Rexroth R901018075

A power unit becomes simpler when the valve covers its own pilot oil demand. The 4WRZE25W9-325-7X/6EG24N9ETK31/A1D3M does so with internal supply and internal return while controlling 325 l/min nominal flow in size 25.

Benefits

• Internal pilot oil supply and internal return, so the power unit needs no pilot pump.
• 325 l/min nominal flow, 870 l/min maximum, operating pressure up to 350 bar.
• Integrated pressure reducing valve provides constant pilot pressure taken from the working circuit.
• Command value ±10 V DC through a 7-pole connector (6 + PE), supply 24 V DC.
• Symbol W9, three switching positions, concealed auxiliary actuation, weight 20.52 kg.

Applications

The valve fits presses, lift tables and forging hammers with a compact power unit that has no separate pilot circuit. At 325 l/min there is reserve for fast approach movements. The prerequisite is a working pressure that reaches the minimum pilot pressure of the range.

Manufacturer

Bosch Rexroth, material number R901018075. Data sheet RE 29115 states minimum pilot pressure, characteristic curves and connection dimensions, RE 07600-B adds general data.
