Proportional Directional Valve 4WRDE25W8-350L-6X/MXYWG/24A5 - Bosch Rexroth R901553363

Load changes push a spool without feedback away from its target position. This size 25 valve measures that position internally and is actuated from a dedicated pilot circuit, at 350 l/min nominal flow and up to 350 bar.

Key benefits

• Internal spool position feedback, with the control deviation corrected in the on-board electronics
• External pilot oil supply and external return, keeping shifting behaviour separate from working pressure
• 350 l/min nominal flow at 350 bar, with flow up to 870 l/min
• Command value ±10 V, 24 V DC supply, 7-pole connector (6 + PE) to EN 175201-804
• Spool symbol W8, mounting pattern ISO 4401-08-08-0-05, 3 switching positions, 17.5 kg

Applications

Intended for forming presses and test rigs with strongly varying cylinder load. The separate pilot circuit permits function tests before the main drive runs. Both pilot lines have to be provided on the subplate.
