Proportional Directional Valve 4WRZE25W6-325-7X/6EG24EK31/A1M - Bosch Rexroth R900728782
For axes rated at 325 l/min nominal flow, this pilot-operated proportional directional valve in size 25 meters oil steplessly. Spool symbol W6 blocks all four ports in mid position, pilot oil is supplied internally and returned externally. Operating pressure up to 350 bar.

Description
Metering 325 l/min independently of load calls for a pilot stage that also closes cleanly at standstill. The 4WRZE25W6-325-7X provides exactly that mid position through spool symbol W6 and passes up to 870 l/min once the cylinder moves into fast traverse.
Benefits
- 325 l/min nominal flow, rated for size 25 and 350 bar operating pressure
- Spool symbol W6 keeps all four ports blocked in mid position
- Internal pilot oil supply saves a dedicated pilot line, the return stays external
- Up to 870 l/min peak flow for short fast traverse phases
- Command value plus/minus 10 V straight into the on-board electronics, no external amplifier needed
- Connection diagram ISO 4401-08-08-0-05, weight 20.58 kg
Applications
Suited to forming machines and hydraulic drives that must hold position safely between two working strokes. Internal pilot oil supply makes sense where main pressure stays high enough during operation. Size 25 allows a direct swap onto existing subplates.
