Proportional Directional Valve 4WRZE10W9-25-7X/6EG24N9EK31/A1D3M - Bosch Rexroth R901211061

The small nominal flow of 25 l/min resolves creep motion finely, while external pilot oil return keeps the pilot spool free of counter pressure. This combination is tailored to positioning tasks in circuits with a loaded tank line.

Benefits

• 25 l/min nominal flow for fine positioning moves in the low speed range
• External pilot oil return keeps the pilot spool free of counter pressure in the tank line
• Internal pilot oil take-off saves the additional pressure line
• Operating pressure up to 315 bar, spool symbol W9, 3 switching positions, 4 ports
• Weight 9.18 kg, NBR seals, ±10 V command through the on-board electronics

Applications

Test rigs, positioning axes and infeed drives with short travel are the typical applications. The dedicated pilot return is advisable when several valves discharge into the same return line. Mounting is on a subplate to ISO 4401-05-05-0-05.
