Proportional Directional Valve 4WRDE10E100L-6X/VXY/24A1 - Bosch Rexroth R901559540

This pilot-operated proportional directional valve of the 4WRDE series combines internal spool position feedback with 100 l/min nominal flow and a maximum operating pressure of 350 bar. Spool symbol E gives a fine control range around the centre position, where starting and decelerating an axis can be metered.

Benefits

• 100 l/min nominal flow and 170 l/min maximum flow at 7.3 kg valve weight
• Maximum operating pressure 350 bar with FKM seals for HL hydraulic fluid
• Internal spool position feedback holds the relation between command value and opening across all 3 switching positions
• Analogue command value ±10 V, supply 24 VDC, evaluated by the on-board electronics at the valve
• External pilot oil supply and external pilot oil return, 4 ports on mounting pattern ISO 4401-05-05-0-05

Applications

The valve is used on cylinder axes with a high oil demand, for example on forming presses, roll adjustment drives and large test rigs. Symbol E suits axes that have to start sensitively out of the centre position. An external pilot circuit must be available, because the pilot stage is not fed from port P.
