Proportional Directional Valve 4WRZ10W8-85-7X/6EG24N9TK4/D3M - Bosch Rexroth R901024337

In centre position the spool geometry decides whether the cylinder holds or is relieved. The 4WRZ10W8-85-7X/6EG24N9TK4/D3M uses spool symbol W8 for that and controls at 85 l/min nominal flow in size 10.

Benefits

• Spool symbol W8 with 3 switching positions, a defined arrangement of the 4 ports without a command value.
• 85 l/min nominal flow, 170 l/min maximum flow at 315 bar.
• External pilot oil supply, internal return, with a pressure reducing valve in the pilot stage.
• Electrical with external electronics, 24 VDC, 7-pole plug (6 + PE) to EN 175201-804.
• 8.19 kg, NBR seals, HL fluid, subplate mounting to ISO 4401-05-05-0-05.

Applications

The application is on axes that should take a defined oil path when de-energised. The large 85 l/min step suits cylinders with a high travel speed. External pilot supply keeps the pilot stage working even while the main circuit is unloaded.
