SDHRZE-A 3 way, direct operated proportional pressurereducing valves, size 06.They operate is association with electronicdrivers, see section 2, which supply theproportional solenoids with proper current toalign the pressure regulation to the referencesignal.Technical characteristicsThey provide the pressure reduction on ports A,or B or A and B, depending on the valve model.The direct execution performs low internalleakages, fast response and low hysteresis.The solenoid coils are plastic encapsulated withinsulation class H and they are available withdifferent nominal resistances depending to thevoltage supply (12 VDCor 24 VDC) and to theelectronic driver type, see section 2and 3
