At 520 l/min the pilot stage decides whether the axis keeps its ramp. The 4WRZ32E1-520-7X/6EG24N9K4/D3M receives pilot oil through X from a dedicated circuit and drains it through Y, at operating pressures up to 350 bar.

Total price
The larger the flow, the more a collapsing pilot pressure shows up in the motion. The 4WRZ32E1-520-7X/6EG24N9K4/D3M is therefore piloted entirely externally and carries a 520 l/min nominal flow in size 32.
Advantages
- Nominal flow of 520 l/min, up to 1600 l/min total flow.
- External pilot oil supply through X and external return through Y.
- Pressure reducing valve in the pilot stage holds pilot pressure at a fixed value.
- Operating pressure up to 350 bar, spool symbol E1, three switching positions.
- Concealed manual override, connection diagram ISO 4401-10-09-0-05.
- Weight of 43.4 kg, NBR seals, driven by external amplifier electronics.
