Proportional Directional Valve 4WRLE25W6-350LJ-4X/MXY/24A1 - Bosch Rexroth R901404336

A dedicated pilot circuit pays off as soon as main pressure collapses during the cycle. The 4WRLE25W6-350LJ-4X/MXY/24A1 therefore draws pilot oil from outside and drains it there too, at 350 l/min nominal flow and 350 bar operating pressure.

Benefits

• Spool symbol W6 with ports blocked in mid position and a linear characteristic across the command range.
• External pilot circuit in both directions, so pilot pressure and pilot drain are independent of the main circuit.
• 350 l/min nominal flow, maximum flow up to 1250 l/min at 350 bar.
• ±10 V command on on-board electronics, 24 VDC supply, 3 switching positions on 4 ports.
• CE conformity, 19.44 kg valve mass, mounting pattern ISO 4401-08-08-0-05.

Applications

Worth choosing on presses and hoists whose system pressure drops sharply at load change, and on power units feeding several axes from one pilot pump. The subplate has to carry X and Y lines. Where those lines are missing, the internal pilot version is the simpler route.
