Description

High back pressure in the tank line distorts pilot behaviour. The 4WRZE10W8-85-7X/6EG24N9EK31/A1D3V therefore takes pilot oil internally but drains it externally, while metering 85 l/min at up to 315 bar.

Benefits

Internal pilot supply with external return - control behaviour independent of tank back pressure.
85 l/min nominal flow in size 10, 170 l/min maximum throughput.
±10 V setpoint, on-board electronics, 24 VDC supply.
Operating pressure up to 315 bar, spool symbol W8, 3 switching positions.
Mass 8.47 kg, FKM seals, HL hydraulic fluid.

Applications

Recommended for plants running long or heavily filtered return paths where tank pressure rises noticeably. Axes that reverse often also gain, because the pilot circuit then relieves cleanly.

Manufacturer

Bosch Rexroth lists this valve under material number R900974142, type code 4WRZE10W8-85-7X/6EG24N9EK31/A1D3V. Characteristic curves, performance limits and installation dimensions are documented in datasheet RE 29115, the range overview in RE 07600-B.
