If the return line builds back pressure, pilot oil return belongs on the outside. The 4WRZE25W9-325-7X/6EG24N9EK31/F1D3V routes it externally, feeds the pilot stage internally and controls 325 l/min nominal flow at 350 bar. Command value 4 to 20 mA, 20.85 kg.

Total price
Filters, coolers and long return lines create back pressure that acts on the pilot stage. The 4WRZE25W9-325-7X/6EG24N9EK31/F1D3V therefore takes pilot oil return out separately while controlling 325 l/min nominal flow in size 25.
Benefits
- External pilot oil return, pilot pressure stays clear of back pressure in the tank line.
- Internal pilot oil supply, one feed line less in the manifold.
- 325 l/min nominal flow, up to 870 l/min maximum flow.
- Command value 4 to 20 mA, on-board electronics at 24 V DC.
- Symbol W9 with a pressure reducing valve in the pilot stage, 350 bar operating pressure.
- 20.85 kg, FKM seals, UKCA evidence SI2016/1091.

Applications
The version is used in power units with a return filter plus an oil cooler in the tank line. Without its own line the pilot return would sit on a fluctuating pressure level there, which would shift the characteristic of the valve.
Manufacturer
Bosch Rexroth, material number R901013241, product family 4WRZ(E). The 6EG24N9EK31 code separates this pilot oil routing from the fully internal variant. Characteristic curves and installation dimensions are in data sheet RE 29115 and RE 07600-B.
