Proportional Directional Valve 4WRDE25V350L-6X/MXY/24F1 - Bosch Rexroth R901508476

An axis whose pilot stage depends on main pressure turns sluggish as soon as pressure collapses. The 4WRDE25V350L-6X/MXY/24F1 has separate X and Y ports for that reason, works with the V spool and meters 350 l/min at 350 bar from a 4...20 mA current command.

Benefits

• External supply through X and external drain through Y, pilot pressure stays available even during a pressure drop.
• V spool with 350 l/min nominal flow, the body carries up to 870 l/min.
• 350 bar operating pressure across four ports and three switching positions.
• 4...20 mA command on a 24 V DC supply, electronics built into the valve.
• 17.5 kg on ISO 4401-08-08-0-05, NBR seals, HL hydraulic fluid.

Applications

The valve belongs where a separate control pressure circuit already exists, for example in press lines and large test facilities. A dedicated pilot circuit also allows travel at very low working pressure. Piston position feedback holds the relation between signal and opening.

Manufacturer

Bosch Rexroth, type designation 4WRDE25V350L-6X/MXY/24F1, material number R901508476, product family 4WRDE. The electronics sit inside the unit, so a separate amplifier card is unnecessary.
