Proportional Directional Valve 4WRDE27V500L-6X/MXT/24A1 - Bosch Rexroth R901557290

Large cylinders on forging presses plus sheet forming lines demand flow without losing control quality. The 4WRDE27V500L-6X/MXT/24A1 in size 27 passes 500 l/min nominal flow, allows 1000 l/min at peak, plus draws pilot oil from an external circuit while draining internally.

Key benefits

• Nominal flow of 500 l/min alongside a peak value of 1000 l/min serves fast large bore cylinders.
• External pilot oil supply with internal return keeps the pilot stage quick even when main pressure dips.
• Operating pressure up to 270 bar with internal piston position feedback for stable holding.
• On-board electronics on a plus or minus 10 V command value, no amplifier card in the cabinet.
• Interface ISO 4401-08-08-0-05, mass of 19.5 kg, NBR seals for HL mineral oil.

Applications

Valves of this size work in forging presses, sheet forming lines plus hydro turbine governors. Given 19.5 kg of mass alongside high flow, plan a stiff subplate together with short pipe runs. The electrical connection is 7-pole to EN 175201-804.

Manufacturer

Bosch Rexroth lists the valve as 4WRDE27V500L-6X/MXT/24A1 under material number R901557290. The MXT code describes pilot oil routing plus separates this build from the MPT or MXY versions of the same size.
