Total price
A dedicated pilot circuit with its own pump and its own return makes the switching movement independent of what happens in the main line. The 4WRZ32W8-360-7X/6EG24N9K4/M uses exactly that: pilot oil arrives externally and leaves externally, at 360 l/min nominal flow in size 32.
Benefits
- External pilot oil supply and external return, pilot pressure and relief are decoupled from the working circuit.
- 360 l/min nominal flow, up to 1600 l/min throughput across 4 ports in size 32.
- 350 bar maximum operating pressure using NBR seals for HL hydraulic fluid.
- Concealed auxiliary actuation, spool symbol W8, the axis can be checked before the electronics are wired.
- 43.3 kg weight, ISO 4401-10-09-0-05 pattern, mounting follows the size 32 standard.

Applications
The valve is used in plants running a central pilot circuit, for example presses carrying several pilot-operated main valves. Because the return is external too, a loaded tank channel does not disturb the pilot stage. Setpoints come from an external amplifier through the 7-pole plug.
