Proportional Directional Valve 4WRZ10W9-85-7X/6EG24N9K4/D3M - Bosch Rexroth R901225764

The 4WRZ10W9-85-7X/6EG24N9K4/D3M routes pilot oil supply and pilot oil return separately to the outside and keeps pilot pressure constant through an integrated pressure reducing valve. Nominal flow is 85 l/min at 315 bar maximum operating pressure.

Benefits

• External pilot oil supply and external pilot oil return
• Integrated pressure reducing valve keeps pilot pressure constant
• Nominal flow 85 l/min, flow up to 170 l/min
• Spool symbol W9, 3 switching positions, size 10
• Maximum operating pressure 315 bar, weight 8.18 kg
• Electrical with external electronics, ISO 4401-05-05-0-05 interface

Applications

Meant for machines whose pilot pressure comes from a shared network under changing load. The pressure reducing valve decouples the pilot stage from those variations. Supply and return are piped separately.
