Proportional Directional Valve 4WRDE25V1-350L-6X/MXY/24F1 - Bosch Rexroth R901571368

Driving a large cylinder from a control cabinet far away calls for a command signal that survives the cable run. The 4WRDE25V1-350L-6X/MXY/24F1 accepts a 4...20 mA current command and turns it through the V1 spool into 350 l/min nominal flow at 350 bar.

Benefits

• 4...20 mA current command through a 7-pole connector (6 + PE) to EN 175201-804, immune to voltage drop over long cable runs.
• 350 l/min nominal flow at 350 bar operating pressure, the size 25 body allows up to 870 l/min.
• On-board electronics on 24 V DC, so no amplifier card is wired into the cabinet.
• External pilot oil supply plus external pilot oil return keep the pilot circuit independent of main pressure.
• ISO 4401-08-08-0-05 interface with four ports, three switching positions and 17.5 kg installed weight.

Applications

The valve controls feed motion and position of large differential cylinders in presses, test rigs and handling axes. Internal piston position feedback keeps repeatability stable under changing load. NBR seals and HL hydraulic fluid suit common mineral oil systems.

Manufacturer

Bosch Rexroth, type designation 4WRDE25V1-350L-6X/MXY/24F1, material number R901571368, product family 4WRDE. The electronics sit inside the unit, so a separate amplifier card is unnecessary.
