Proportional Directional Valve 4WRZ25W8-220-7X/6EG24N9K4/V - Bosch Rexroth R900958169
Not every axis needs the full throughput of size 25. This 4WRZ25W8-220-7X is graded to 220 l/min nominal flow, keeps the ISO 4401-08-08-0-05 interface and works to 350 bar operating pressure. Spool symbol W8, FKM seals, weight 20.14 kg.

Description
A smaller nominal stage on the familiar mounting face makes matching axis speed to valve easier. The 4WRZ25W8-220-7X/6EG24N9K4/V offers 220 l/min nominal flow in size 25 while passing up to 870 l/min at maximum.
Benefits
- Nominal flow 220 l/min, finer resolution of the command value than the 325 l/min stage of the same valve
- Maximum flow 870 l/min, maximum operating pressure 350 bar
- Spool symbol W8, 3 switching positions, 4 ports
- External pilot oil supply plus external pilot oil return
- External electronics at 24 VDC, 7-pole connector (6 + PE) to EN 175201-804
- FKM seals, concealed auxiliary actuation, weight 20.14 kg
Application
The 220 l/min stage makes sense on axes whose target speed sits in the lower third of the range. The mounting face stays ISO 4401-08-08-0-05, so changing between nominal stages needs no rework of the manifold. HL hydraulic fluid is released.
