Description

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

Application

Fitted on lifting plus press axes where the load has to stay put at rest. Ample flow reserve covers fast traverse phases without losing fine control. An operating pressure of 270 bar matches plants running moderate system pressure.
