Proportional Directional Valve 4WRDE10V100L-6X/MXY/24A1 - Bosch Rexroth R901570607

Whether an axis coasts down without pressure at shutdown or stops hard is decided by the spool symbol. The 4WRDE10V100L-6X/MXY/24A1 uses symbol V for that and carries 100 l/min nominal flow at operating pressures up to 350 bar.

Benefits

• Spool symbol V sets the mid position behaviour and therefore how the axis coasts down.
• 100 l/min nominal flow in size 10 on the ISO 4401-05-05-0-05 mounting pattern.
• Internal spool position feedback gives reproducible curves up to 350 bar.
• External pilot oil supply and external return through ports X and Y.
• Plus or minus 10 V command, 24 VDC at a 7-pole connector (6 + PE) to EN 175201-804, NBR seals, 7.5 kg.

Applications

The valve serves lifting and slewing axes that should come to rest in a controlled way after shutdown. A separate pilot circuit keeps the pilot stage steady even when working pressure collapses. Range maximum flow reaches 170 l/min.
