Proportional Directional Valve 4WRDE25V1-350L-6X/MPT/24F1 - Bosch Rexroth R901532100

Replacing an axis valve is usually decided by the hardware already in place rather than by the catalogue. The 4WRDE25V1-350L-6X/MPT/24F1 fits the widely used ISO 4401-08-08-0-05 interface, takes a 4...20 mA current command and delivers 350 l/min nominal flow at 350 bar with pilot oil routed internally.

Benefits

• ISO 4401-08-08-0-05 interface with four ports and three switching positions, matching subplates already installed.
• 4...20 mA current command, robust against interference in cable ducts shared with power lines.
• Internal pilot oil supply and internal return, no X or Y lines have to be laid.
• 350 l/min at 350 bar, V1 spool, body rated up to 870 l/min.
• On-board electronics, 24 V DC, 17.5 kg, NBR seals for HL hydraulic fluid.

Applications

The valve replaces older axis valves in presses, recycling plants and heavy duty axes. With the electronics inside the valve, only the command line remains in the cabinet. Internal piston position feedback keeps the relation between signal and flow constant.

Manufacturer

Bosch Rexroth, type designation 4WRDE25V1-350L-6X/MPT/24F1, material number R901532100, product family 4WRDE. The electronics sit inside the unit, so a separate amplifier card is unnecessary.
