Proportional Directional Valve 4WRLE25E400LJ-4X/MXY/24A1 - Bosch Rexroth R901396318

Large main axes need flow together with a characteristic that tracks the command value across the whole span. The 4WRLE25E400LJ-4X/MXY/24A1 proportional directional valve in size 25 handles 400 l/min nominal flow and works up to a maximum operating pressure of 350 bar.

Benefits

• 400 l/min nominal flow - flow up to 1250 l/min at size 25, installed weight 18.58 kg.
• External pilot oil supply and external pilot oil return - pilot control stays independent of pressure in the main circuit.
• Spool symbol E with 3 switching positions - linear relation between command value and flow across 4 ports, internal spool position feedback.
• On-board electronics with ±10 V command value - 24 VDC supply through a 7-pole connector (6 + PE) to EN 175201-804.
• Connection diagram ISO 4401-08-08-0-05 - subplate mounting to standard, NBR seals for HL hydraulic fluid, CE conformity.

Applications

The valve drives main axes on presses, hoists and test rigs that bring their own pilot circuit. At 400 l/min nominal flow there is headroom up to the 1250 l/min flow limit. Internal spool position feedback keeps command value and spool travel aligned over the stroke. Where X and Y lines are missing on the manifold, an internal pilot version fits instead.
