Proportional Directional Valve 4WRZ32E1-520-7X/6EG24N9ETK4/M - Bosch Rexroth R901039681

Large cylinders need oil, and the bigger the nominal stage, the more every extra pipe run costs. The 4WRZ32E1-520-7X/6EG24N9ETK4/M combines 520 l/min nominal flow with internal pilot oil supply and internal return.

Benefits

• 520 l/min nominal flow, up to 1600 l/min throughput, laid out for main axes with large swept volume.
• Pilot oil supplied and returned internally, the subplate stays limited to the standard porting pattern.
• Spool symbol E1 across 3 switching positions over 4 ports to ISO 4401-10-09-0-05.
• 350 bar maximum operating pressure, 41.66 kg weight, NBR seals for HL hydraulic fluid.
• Concealed auxiliary actuation, during setup or a power failure the spool can be moved by hand.

Applications

The valve serves feed and lift axes of large presses, sheet metal lines and test rigs for heavy components. Internal pilot routing assumes a sufficiently high system pressure throughout the movement. An external amplifier takes care of the command signal.
