Proportional Directional Valve 4WRDE10VN100L-6X/MXY/24A5 - Bosch Rexroth R901506981

Pilot pressure kept separate from the main circuit stays stable even when system pressure collapses. This NG10 version takes pilot oil from outside plus discharges it outside, metering 100 l/min of nominal flow under closed-loop spool control at a maximum operating pressure of 350 bar.

Benefits

• External pilot oil supply with external pilot oil return keep pilot pressure clear of the main circuit
• Nominal flow of 100 l/min, maximum flow 170 l/min in size 10
• Spool symbol V with linear characteristic curve, 3 switching positions, 4 ports
• A ±10 V command value at on-board electronics with internal spool position feedback on 24 VDC
• NBR seals for HL hydraulic fluid, operating pressure to 350 bar, mass 7.5 kg

Application

Installed on axes whose system pressure drops sharply each cycle, as in accumulator operation. A dedicated pilot circuit keeps spool control working through those phases. Common applications are test rigs, forming machines plus clamping systems.
