Shared return headers create back pressure that can upset the pilot stage of a large valve. The 4WRZ25E325-7X/6EG24N9EK4/M therefore routes the pilot return externally while the supply stays internal, with symbol E and 325 l/min nominal flow.
Benefits
- External pilot oil return, independent of header back pressure
- Internal pilot oil supply taken from working pressure
- Symbol E with 325 l/min nominal flow, flow up to 870 l/min
- Maximum operating pressure 350 bar in size 25
- External electronics, 24 VDC, 7-pole connector (6 + PE) to EN 175201-804
- Weight 19.96 kg, NBR seals
