In densely populated size 32 valve blocks there is rarely room for additional pilot drillings. The 4WRZ32W9-520-7X/6EG24N9ETK4/M solves that with internal pilot oil supply and internal return, and still provides 520 l/min nominal flow.

Key benefits

  • Pilot oil fed and drained internally, the subplate needs no pilot drillings.
  • 520 l/min nominal flow, maximum flow 1600 l/min, operating pressure up to 350 bar.
  • Spool symbol W9, 3 switching positions, 4 ports, connection pattern ISO 4401-10-09-0-05.
  • 40.2 kg weight in size 32, NBR seals for HL hydraulic fluid.
  • Concealed manual override for commissioning and emergency travel, without pilot pressure reducing valve.
  • Driven by external electronics, 24 VDC supply, 3-pole connector (2 + PE).

Applications

Meant for retrofits on blocks whose drilling pattern is not to be changed again. A closed pilot circuit shortens assembly and reduces the number of sealing points. With 520 l/min nominal flow the valve suits main cylinders on presses and hoists.
