Accumulator systems run at widely varying pressure, so pilot control needs its own source there. This 4WRZ32E520 is piloted externally on both paths, blocks through symbol E and converts 520 l/min nominal flow. Operating pressure up to 350 bar, 43.4 kg.

A nominal flow of 520 l/min meets a blocking symbol E and a fully external pilot circuit here. 520 l/min are set without pilot pressure depending on the state of the main circuit. 350 bar are permitted.
Advantages
- Nominal flow 520 l/min, maximum flow up to 1600 l/min
- Symbol E blocks in mid position and holds the load
- External pilot oil supply and external return, independent pilot circuit
- Pressure reducing valve in the pilot stage, concealed auxiliary actuation
- External amplifier electronics on 24 VDC, connection diagram ISO 4401-10-09-0-05
- FKM seals for HL hydraulic fluid, operating pressure up to 350 bar, 43.4 kg
