A dedicated pilot circuit plus a pressure reducing valve makes the pilot stage doubly independent of working pressure. The 4WRZ32E360-7X/6EG24N9K4/D3M is built that way and controls 360 l/min nominal flow at a maximum of 350 bar.

Total price
Where pilot oil arrives from outside and leaves outside again, the switching movement no longer depends on the state of the main line. The 4WRZ32E360-7X/6EG24N9K4/D3M adds a pressure reducing valve ahead of the pilot stage and works at 360 l/min nominal flow.
Benefits
- External pilot oil supply and external return, pilot pressure and relief come from a separate circuit.
- Pressure reducing valve in the pilot circuit, control pressure stays inside the permitted range even when supply fluctuates.
- 360 l/min nominal flow, peaks up to 1600 l/min in size 32.
- Spool symbol E, 43.84 kg weight, ISO 4401-10-09-0-05 pattern across 4 ports.
- 350 bar maximum operating pressure using NBR seals for HL hydraulic fluid.

Applications
The valve is used in plants with a central pilot supply feeding several pilot-operated main valves together. Because the return is external as well, a loaded tank channel does not act back on the pilot stage. An external amplifier at 24 VDC takes care of the command signal.
