Proportional Directional Valve 4WRLE25W6-350LJ-4X/MPT/24A1 - Bosch Rexroth R901484559

The simplest piping results when the valve takes pilot oil from P itself and drains it internally to tank. The 4WRLE25W6-350LJ-4X/MPT/24A1 is built that way while controlling 350 l/min nominal flow at 350 bar.

Benefits

• Internal pilot oil supply and internal pilot oil return make X and Y lines unnecessary, keeping the subplate simple.
• Spool symbol W6 blocks A and B at centre, so the axis holds position when the signal stops.
• 350 l/min nominal flow, maximum flow up to 1250 l/min, operating pressure 350 bar.
• On-board electronics with ±10 V command at 24 VDC, 7-pole connector (6 + PE) to EN 175201-804.
• CE conformity, 19.4 kg valve mass on mounting pattern ISO 4401-08-08-0-05.

Applications

The right choice for power units without a separate pilot pump, which covers most standard press and lifting applications. It assumes a system pressure that stays above pilot level. If port P pressure collapses during the cycle, the version with external pilot oil supply is safer.
