Proportional Directional Valve 4WRLE16E250LJ-4X/MXY/24A1 - Bosch Rexroth R901404332

When an axis runs on accumulator supply, system pressure drops across the stroke. The 4WRLE16E250LJ-4X/MXY/24A1 keeps its pilot stage clear of that because control oil is fed through X and drained through Y, at 250 l/min nominal flow and a plus or minus 10 V command.

Benefits

• External pilot oil supply and external return, so control pressure stays independent of working pressure.
• 250 l/min nominal flow in size 16, operating pressure up to 350 bar.
• Plus or minus 10 V command at the on-board electronics with spool position feedback.
• Spool symbol E, 3 switching positions, linear characteristic curve, 4 ports.
• Mounting pattern ISO 4401-07-07-0-05, NBR seals, weight 11.55 kg, CE conformity.

Applications

This version is needed on accumulator presses, on forging plants and on testing machines with strongly changing load. The separate control circuit keeps switching time available even at the end of the accumulator stroke. The 250 l/min nominal flow covers medium to large cylinders.
