Proportional Directional Valve 4WRDE25E350L-6X/MXYWG/24A5 - Bosch Rexroth R901545721

Choosing a directional valve often starts with the spool symbol rather than with any other figure. The 4WRDE25E350L-6X/MXYWG/24A5 is built around the E spool, receives pilot oil externally through X and Y and meters 350 l/min at 350 bar from a ±10 V command.

Benefits

• E spool in size 25 with three switching positions and four ports.
• 350 l/min nominal flow at 350 bar, the body limit stands at 870 l/min.
• External pilot circuit through X and Y, independent of the working pressure of the axis.
• ±10 V command with on-board electronics on a 24 V DC supply.
• 17.5 kg on the ISO 4401-08-08-0-05 interface, NBR seals.

Applications

Typical applications are feed axes on presses, lifting gear and test rigs with changing load direction. Internal piston position feedback holds the command value even as load pressure rises. For plants running on a current signal there is a 4...20 mA version.

Manufacturer
