Description

High or fluctuating tank pressure acts back on the pilot stage when the return runs internally. The 4WRZ25E1-220-7X/6EG24N9EK4/D3V therefore drains the pilot oil return externally and supplies the pilot stage internally.

Benefits

Internal pilot oil supply, external return, independent of tank pressure
Pressure reducing valve in the pilot stage, spool symbol E1
Nominal flow 220 l/min, maximum flow 870 l/min
Pilot-operated spool valve with concealed auxiliary actuation
Maximum operating pressure 350 bar, FKM seals, weight 20.46 kg

Applications

Meant for plants with a return filter or back pressure in the tank circuit, such as large power units with a shared return manifold. Separate draining keeps the pilot stage stable. ISO 4401-08-08-0-05 interface, size 25.
