Proportional Directional Valve 4WRZE10W6-50-7X/6EG24N9K31/A1V - Bosch Rexroth R901115824

This valve works with a voltage interface: ±10 V sets direction and opening, and the electronics on the valve convert the signal into 50 l/min nominal flow. The pilot circuit is fed and returned externally, and no pressure reducing valve for the pilot oil is fitted.

Benefits

• Command value ±10 V, evaluated by the on-board electronics at the valve, supply 24 VDC
• 50 l/min nominal flow at 8.66 kg valve weight, maximum flow 170 l/min
• External pilot oil supply and external pilot oil return, so the pilot circuit can be sized independently of the working pressure in port P
• Spool symbol W6, 3 switching positions and 4 ports on mounting pattern ISO 4401-05-05-0-05
• FKM seals for HL hydraulic fluid at a maximum operating pressure of 315 bar

Applications

The valve suits systems that already run a separate pilot circuit, such as presses, machine tools and test rigs with their own pilot pump. Because the pilot oil comes from outside, the pilot stage stays supplied even when the working pressure drops. The concealed auxiliary actuation lets the spool be moved during commissioning.
