Proportional Directional Valve 4WRDE25V1-350L-6X/MPT/24A1 - Bosch Rexroth R901545043

A compact power unit rarely leaves room for extra pilot oil piping. The 4WRDE25V1-350L-6X/MPT/24A1 therefore supplies its pilot circuit internally and drains it internally while metering 350 l/min at 350 bar from a ±10 V command.

Benefits

• Internal pilot oil supply plus internal pilot oil return, only the four ports of the ISO 4401-08-08-0-05 subplate stay in use.
• ±10 V command value straight from a standard controller card through a 7-pole connector (6 + PE).
• 350 l/min at 350 bar with the V1 spool, body limit 870 l/min.
• Piston position feedback inside the valve for a stable characteristic curve, supply 24 V DC.
• 17.5 kg weight, NBR seals, HL hydraulic fluid.

Applications

Typical places of use are clamping circuits on machine tools, infeed axes and compact press power units. Because no separate pilot circuit has to be piped, commissioning takes less time. Where main pressure swings strongly, the externally supplied version is the better choice.

Manufacturer

Bosch Rexroth, type designation 4WRDE25V1-350L-6X/MPT/24A1, material number R901545043, product family 4WRDE. The electronics sit inside the unit, so a separate amplifier card is unnecessary.
