Total price
Large cylinders need flow, and it has to be controlled cleanly. The 4WRZE25W9-325-7X/6EG24N9K31/F1D3M provides 325 l/min nominal flow in size 25, accepts the command signal as 4 to 20 mA and runs on a fully external pilot circuit.
Benefits
- 325 l/min nominal flow, around 50 percent more than the 220 l/min version of the same range.
- External pilot oil supply and external return, suited to power units with their own pilot pump.
- Pressure reducing valve in the pilot circuit limits pilot pressure independently of working pressure.
- Current command value 4 to 20 mA, supply 24 V DC through a 7-pole connector (6 + PE).
- Symbol W9 with three switching positions, concealed auxiliary actuation, weight 20.74 kg.

Applications
The valve serves main axes of presses, forging lines and large lifting gear. High nominal flow shortens rapid traverse times without spoiling fine control. An external pilot circuit keeps pilot pressure available even when working pressure collapses during the cycle.
