Proportional Directional Valve 4WRZE10W6-85-7X/6EG24N9K31/A1D3V - Bosch Rexroth R901028802

Accumulator plants work between charging and discharging pressure, which can noticeably influence the pilot stage of a valve. The 4WRZE10W6-85-7X/6EG24N9K31/A1D3V therefore hangs on a separate circuit through X and Y and controls 85 l/min nominal flow at up to 315 bar.

Benefits

• External pilot oil supply and external return for a constant control pressure across the whole cycle.
• 85 l/min nominal flow in size 10 against a series maximum flow of 170 l/min.
• Spool symbol W6 with a blocked mid position and 3 switching positions.
• Plus or minus 10 V command, 24 VDC supply through a 7-pole connector (6 + PE) to EN 175201-804.
• Integrated pressure reducing valve, FKM seals, weight 8.48 kg, UKCA conformity.

Applications

Such valves sit on accumulator presses, on emergency lowering circuits and on axes with intermittent oil demand. The separate control circuit keeps switching time equal even at the end of the accumulator stroke. At 85 l/min nominal flow the rapid stroke stays short.
