Proportional Directional Valve 4WRDE25W8-350L-6X/MPYWG/24A5 - Bosch Rexroth R901571665

Control accuracy and installed weight do not have to conflict: the 4WRDE25W8 weighs 9.95 kg, measures spool travel internally and passes 350 l/min nominal flow at up to 350 bar.

Key benefits

• Internal spool position feedback into the on-board electronics, command value ±10 V
• Only 9.95 kg at 350 l/min nominal flow, which eases fitting and replacement
• Internal pilot oil supply with external pilot oil return, one line fewer on the subplate
• 350 bar operating pressure, mounting pattern ISO 4401-08-08-0-05, 4 ports, 3 switching positions
• Flow of up to 870 l/min possible, spool symbol W8, NBR seals rated to hydraulic fluid HL

Applications

Suited to dynamic axes on test rigs, forming machines and handling systems where fast positioning matters. Internal pilot supply requires sufficient system pressure. The pilot drain has to run separately to tank.
