Proportional spool valvesWandfluh AGTel.+41 33 672
DESCRIPTIONDirect operated proportional spool valve inflange design NG10 acc. to ISO 4401-05 with4 ports. The spool valve is designed to the 5chamber principle. The volume flow is adjustedby a Wandfluh proportional solenoid (VDEstandard 0580). Low pressure drop due to thebody design and spool profiling. The spool ismade of hardend steel. The body made of highgrade hydraulic casting for long service life ispainted. The cover and the solenoid are zinccoated.
