Proportional Directional Valve 4WRLE25W8-350LJ-4X/MPY/24A1 - Bosch Rexroth R901515884

Coolers, filters and long collecting lines create return pressure that upsets an internal pilot return. The 4WRLE25W8-350LJ-4X/MPY/24A1 therefore routes its pilot oil out through Y and still regulates 350 l/min at up to 350 bar.

Benefits

• External pilot return through Y, independent of back pressure in the return line
• Internal pilot oil supply, which saves one additional pressure line
• 350 l/min nominal flow, up to 1250 l/min at the limit
• Command value ±10 V from the analog card, 24 V DC supply
• Spool symbol W8, mounting pattern ISO 4401-08-08-0-05, CE compliant
• Mass 19.54 kg, NBR seals, HL hydraulic fluid

Applications

The variant is needed in press lines, foundry plants and power units with a central return manifold. It keeps the pilot stage functional where tank pressure sits clearly above zero. The 350 l/min rating is enough for large size 25 cylinders.
