Under full load the switching time of a large valve should stay the same. The 4WRZ32W8-520-7X/6EG24N9TK4/M therefore receives pilot oil from a separate circuit, returns it internally and controls 520 l/min nominal flow at 350 bar.

Frequently Bought Together

When an axis reverses under load, pressure in the main line drops briefly and an internally supplied pilot stage turns sluggish. The 4WRZ32W8-520-7X/6EG24N9TK4/M avoids that through external pilot oil supply while providing 520 l/min nominal flow.

Benefits

  • External pilot oil supply, the switching movement stays even when reversing under load.
  • Internal pilot oil return, the tank channel of the subplate is enough for relief.
  • 520 l/min nominal flow, throughput up to 1600 l/min in size 32.
  • Spool symbol W8, 3 switching positions, 43.4 kg, subplate mounting to ISO 4401-10-09-0-05.
  • Concealed auxiliary actuation, for setup mode and fault finding without electronics.

Applications

The valve serves reversing axes of presses, tipping and slewing drives and test rigs with alternating load direction. A dedicated pilot circuit pays off where several axes switch at the same time. An external amplifier at 24 VDC provides the command signal.
