At 520 l/min nominal flow the tank channel carries a heavy stream, so the pilot return belongs in a line of its own. This version does that while supplying itself internally, spool symbol E, size 32, operating pressure up to 350 bar, 42.9 kg.

Total price
When 520 l/min flow back through the tank channel, there is no unpressurised oil left there for the pilot stage. The 4WRZ32E520-7X/6EG24N9EK4/V therefore draws pilot oil internally but drains it through a dedicated port, keeping spool position reproducible.
Key benefits
- An external pilot return separates the pilot stage from the heavily loaded tank channel.
- Internal pilot oil supply, a separate pilot pump is not needed.
- 520 l/min nominal flow in size 32, maximum flow 1600 l/min.
- Spool symbol E, 3 switching positions, 4 ports, connection pattern ISO 4401-10-09-0-05, up to 350 bar.
- 42.9 kg weight, FKM seals, HL hydraulic fluid.
- Concealed manual override, without pilot pressure reducing valve, external electronics on 24 VDC.

Applications
A fit for main axes that push large volumes of oil to tank when lowering or opening. The dedicated return keeps the pilot stage clear of back pressure during that phase. At 520 l/min nominal flow the valve serves cylinders on presses, hoists and test rigs in size 32.
