Proportional Directional Valve 4WRZE10E85-7X/6EG24N9K31/A1V - Bosch Rexroth R900969955

When an old servo axis is converted to proportional technology, pilot circuit and piping usually stay in place. The 4WRZE10E85-7X/6EG24N9K31/A1V builds on that: external pilot oil supply, external return, a ±10 V command value and 85 l/min nominal flow at operating pressures up to 315 bar.

Benefits

• External pilot oil supply and external pilot oil return, existing X and Y lines remain usable.
• ±10 V command value on the on-board electronics, matched to analogue outputs already installed.
• 85 l/min nominal flow, maximum flow 170 l/min in size 10.
• Spool symbol E, 3 switching positions and 4 ports, connection diagram ISO 4401-05-05-0-05.
• FKM seals for HL hydraulic fluid, 8.66 kg weight.
• Concealed auxiliary actuation for function checks while no control system is connected.

Applications

The valve replaces actuators on machine tools, presses and test rigs whose power unit already provides a pilot supply. Subplate mounting to ISO 4401-05-05-0-05 matches the familiar size 10 hole pattern. At 85 l/min axis speed stays close to the previous design point.
