Proportional Directional Valve 4WRDE25V220L-6X/MXY/24A1 - Bosch Rexroth R901507462

Sensitive positioning works out only when nominal flow and cylinder size match each other. The 4WRDE25V220L-6X/MXY/24A1 therefore rates 220 l/min in a body that allows up to 870 l/min, following a ±10 V command at 350 bar.

Benefits

• 220 l/min nominal flow instead of the full body rating, which gives finer resolution per volt of command.
• V spool with three switching positions and four ports.
• 350 bar operating pressure at a valve weight of only 17 kg.
• External pilot oil supply and external drain through the X and Y ports.
• ±10 V command on 24 V DC, 7-pole connector (6 + PE) to EN 175201-804.

Applications

The valve fits medium sized positioning axes, infeed movements on presses and test cylinders with short stroke. If more flow is needed later, the ISO 4401-08-08-0-05 interface stays unchanged. NBR seals and HL hydraulic fluid match the usual plant standard.

Manufacturer

Bosch Rexroth, type designation 4WRDE25V220L-6X/MXY/24A1, material number R901507462, product family 4WRDE. The electronics sit inside the unit, so a separate amplifier card is unnecessary.
