Proportional Directional Valve 4WRLE25W8-350LJ-4X/MXY/24F1 - Bosch Rexroth R901519815

In accumulator operation system pressure swings considerably between charge and discharge. The 4WRLE25W8-350LJ-4X/MXY/24F1 therefore draws pilot oil externally through X and discharges it through Y, so the pilot stage works independently and holds 350 l/min under control.

Benefits

• External pilot supply and external return leave the pilot stage untouched by charge and discharge pressure
• Command value 4 to 20 mA, immune to voltage drop on long cables
• 350 l/min nominal flow with a maximum of 1250 l/min in size 25
• Internal spool position measurement for reproducible metering areas
• Spool symbol W8, three switching positions, four ports, operating pressure 350 bar
• Mass 19.38 kg, CE conformity, NBR seals

Applications

The variant drives axes on accumulator presses, forging hammers and cyclic test rigs. Its own pilot circuit maintains actuating speed even during the discharge phase. The current interface keeps the command value clean in electrically loaded surroundings.
