Systems with a central pilot pressure supply want their valves fed from outside. The 4WRZE32W6-520 takes pilot oil through its own ports and drains it the same way while metering 520 l/min at 350 bar. Symbol W6, size 32, weight 44 kg.

If the machine manifold already carries a dedicated pilot pressure line, the pilot stage should be fed from it rather than from working pressure. The 4WRZE32W6-520-7X/6EG24K31/A1D3M is built exactly for that and meters 520 l/min nominal flow at 350 bar.
Benefits
- External pilot oil supply and external return for systems with their own pilot pressure circuit.
- 520 l/min nominal flow, flow up to 1600 l/min in size 32.
- Symbol W6, three switching positions, four ports, 350 bar operating pressure.
- On-board electronics with ±10 V command value, 24 V DC through a 7-pole connector (6 + PE).
- 44 kg weight, NBR seals, HL hydraulic fluid, ISO 4401-10-09-0-05 subplate interface.

Application
This arrangement is found in press lines and steel plant hydraulics where several valves share one pilot circuit. The separate drain keeps pressure surges from the main stage away from the pilot stage. Even if working pressure drops, the axis stays controllable.
