Proportional Directional Valve 4WRTE27V500P-4X/6EG24K31/A1M - Bosch Rexroth R901033479

Accumulator circuits sit unloaded between cycles, and that is when the main valve still has to move. This version of the 4WRTE27V500P draws pilot oil from an external source and discharges it externally, at 500 l/min nominal flow.

Benefits

• External pilot supply and external pilot return, independent of the pressure state of the main circuit.
• Command value plus/minus 10 V, processed by the on-board electronics.
• 500 l/min nominal flow, up to 1000 l/min in size 27.
• Spool symbol V, fine control range, with internal piston position feedback.
• 270 bar operating pressure, NBR seals for hydraulic fluid HL.
• 19.34 kg weight, connection diagram ISO 4401-08-07-0-05.

Applications

The version fits power units with accumulator charging and unloading circuits, for example presses with long holding phases. Pilot oil can come from a small auxiliary pump. Three switching positions across four ports cover a double-acting cylinder.
