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.

Technical data

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.
