Proportional Directional Valve 4WRZ32W8-520-7X/6EG24N9TK4/D3M - Bosch Rexroth R900763679

Fast traverse on large cylinders calls for a correspondingly high nominal flow. The 4WRZ32W8-520-7X/6EG24N9TK4/D3M delivers 520 l/min in size 32 and is piloted from a central pilot pressure line.

Advantages

• Nominal flow of 520 l/min, up to 1600 l/min total flow.
• External pilot feed through X with internal return, only one extra line on the manifold.
• Pressure reducing valve in the pilot stage for steady pilot pressure.
• Operating pressure up to 350 bar, spool symbol W8, three switching positions.
• Concealed manual override, connection diagram ISO 4401-10-09-0-05.
• Weight of 43.85 kg, NBR seals, external amplifier electronics on 24 VDC.

Applications

It is used on rapid traverse axes of large presses, on forging manipulators and on adjusting cylinders in hydraulic engineering. The high nominal flow shortens travel time over long strokes. With an internal return, back pressure in the tank gallery has to be checked.
