Axes carrying a suspended load need a mid position that stops the cylinder from sinking. This pilot-operated proportional directional valve with spool symbol W6 meters 430 l/min of nominal flow, allows peaks to 1850 l/min plus works at a maximum operating pressure of 270 bar.

Benefits

  • Spool symbol W6 with linear characteristic curve suits axes with a suspended load
  • Nominal flow of 430 l/min, maximum flow 1850 l/min in size 27
  • Internal pilot oil supply with external return saves one pilot line on the manifold
  • A ±10 V command value at on-board electronics with internal spool position feedback on 24 VDC
  • Connection diagram ISO 4401-08-08-0-05, CE conformity, NBR seals, mass 20.78 kg
