Four ports in size 32 allow peaks up to 1600 l/min. The 4WRZ32E520-7X/6EG24N9K4/D3M uses that cross section with 520 l/min nominal flow and routes pilot oil in and out through a separate circuit. Maximum operating pressure is 350 bar and the valve weighs 43.44 kg.

Total price
The cross section of a size 32 valve passes up to 1600 l/min for short periods, while the nominal flow defines the control range. The 4WRZ32E520-7X/6EG24N9K4/D3M uses 520 l/min as its nominal stage and works with fully external pilot routing.
Benefits
- 520 l/min nominal flow at up to 1600 l/min throughput, sized for axes with high oil demand.
- Pilot oil fed in and drained externally, pilot pressure and relief are decoupled from the main flow.
- Pressure reducing valve in the pilot circuit, an extra valve in the manifold is dropped.
- Spool symbol E, 43.44 kg weight, subplate mounting to ISO 4401-10-09-0-05.
- 350 bar maximum operating pressure using NBR seals for HL fluid.

Applications
The valve serves main axes of large presses, rolling mill drives and test rigs with high flow demand. Concealed auxiliary actuation eases commissioning, because the hydraulics can be checked separately from the electronics. An external amplifier at 24 VDC provides the command signal.
