Proportional Directional Valve 4WRKE25R3-350P-3X/6EG24K31/A1D3M - Bosch Rexroth R900771042

The 4WRKE25R3-350P-3X/6EG24K31/A1D3M drives axes where a 100 l/min valve would long since be at its limit. Spool symbol R3 runs a linear curve with a fine control range, so small movements stay well metered even at 350 l/min nominal flow. Pilot supply and return are external, and the mounting pattern follows ISO 4401-08-08-0-05.

Benefits

• Nominal flow 350 l/min, maximum 870 l/min, operating pressure to 350 bar.
• Spool symbol R3 with a linear curve and a fine control range around mid position.
• Closed loop spool position control through the internal transducer.
• External pilot supply and return keep the pilot stage clear of load.
• NBR seals, 17.9 kg, mounting pattern ISO 4401-08-08-0-05.

Application

The valve is built into presses, forging plants and test rigs with large cylinder areas. Mineral oil of class HL is intended. The on-board electronics accept ±10 V and are wired through a 7-pole plug to EN 175201-804 on 24 VDC.
