Proportional Directional Valve 4WRDE10E100L-6X/MXY/24A1 - Bosch Rexroth R901515708

A dedicated pilot supply keeps the pilot stage independent of working pressure. The 4WRDE10E100L-6X in the MXY build uses exactly that, feeds and drains pilot oil externally and controls 100 l/min nominal flow in size 10.

Benefits

• External pilot oil supply and external drain decouple pilot control from the main circuit completely.
• Spool symbol E blocks in centre, so the axis holds position without a signal.
• 100 l/min nominal flow and 170 l/min peak flow at 350 bar.
• Internal spool position feedback secures repeatability across the whole command range.
• On-board electronics with ±10 V, connected through a 7-pole (6 + PE) plug according to EN 175201-804.
• 7.3 kg mass, NBR seals, connection diagram ISO 4401-05-05-0-05.

Application

The version is intended for machines with a central pilot pump, for example in press blocks and test rigs. Because pilot pressure stays independent of system pressure, the axis also works cleanly in the low pressure range. Both pilot lines have to be provided on site.
